    Daystar Turbo 040 problem

    Hi, I'm new to this forum as a signed user, but I've read a lot of forum's postings due to my interest in SE/30 I would like to hear your opinion to a problem that I'm facing with my SE/30 and Daystar Turbo 040. First let me tell you the upgrades that my SE/30 has. I have replace the standard hdd with an Apples 2GB scsi. I put 8 x 16MB simms so total ram is 128MB I replace the power supply with one from Stratos The first card in the PDS slot is an Asante Ethernet. The second card is a Daystar Dualport iisi, which with a paper clip i have connect pin 11 & 13 (using a tape) of the PDS-slot for the Daystar Accelarators. In the PDS-slot for the Daystar Accelarators i have connect a Daystar Powercache P33 running at 50Mhz To connect the second card to Asante i used a right angle 120-pin connector The third card is a Radius Pivot PDS Card with 1MB video ram. To connect the third card to Dualport, I used a right angle 120-pin connector. I bought from ebay a Daystar Turbo 040, so to replace the Powercache P33. But when i connect the Turbo040 and powering up the machine, horizontal black and white lines appear in the screen. I have tried with no other cards and no HDD, only motherboard, the Dualport and the Turbo040 but with same results. I have to mention that when i first bought the SE/30 sometimes produces these horizontal black and white lines when powering up. but after a while this phenomena stop. In addition to this, the sound never worked. I can't hear anything from SE/30. I have cleaned the motherboard with alcohol mixture 95% that i bought from pharmacy, using a tooth brush. Many thanks in advance for any replies.
  2. So I have a bit of a problem I recently acquired an SE/30 that was showing symptoms of vertical failure - on boot up it only displayed a single horizontal line. After reflowing the joints on the P1 connector, replacing the TDA1170 on the analog board without any improvement I finally put my SE logic board in the case to verify that it wasn't an analog board. What do you know it wasn't, the analog board on the SE/30 worked perfectly. After probing the logic board with a multimeter, I found that the video PAL IC responsible for generating Vsync (part number 341-0747-A) just wasn't outputting anything. The 60.25hz vertical sync signal was missing. This led me to source a replacement video PAL, which unfortunately didn't change the output whatsoever. It still has a complete loss of vertical sync. I have also checked every single connection in the area in accordance to the SE/30s schematics, and I am now at a complete loss. I am thinking it could be the 74xx series ICs by the video PALs, but quite frankly I have no idea (unfortunately I don't have an oscilloscope). Hopefully someone has encountered this before and can figure it out! Also when a boot floppy is inserted it seems to boot from it (obviously I can't see whats going on but it does react to the keyboard commands to eject the floppy) Finally I just want to stress that this is NOT an analog board issue. My SEs logic board works perfectly fine in the SE/30s case, and the SE/30 still has no vertical when it is in the SE case. 73DE0BC8-6743-41B1-9065-488FA237AF45.heic
  3. OK, so I recently recapped my SE/30 mainboard and it went smoothly, and it resolved a weak sound issue. Little guy worked just fine. Great, I thought, I'll get ahead of the curve and recap my (Astec) PSU and analog board. That goes smoothly as well, and I resoldered a few grey-looking connectors on the ab while I was at it. Reassemble, power on... thin vertical simasimac and no chime. Weird, but OK, time for some obvious checks: - checked voltages, all rock solid coming off the ab, and the usual checks on the mb - double checked the ROM SIM and make sure it's clean and seated. A few greyish pads toward one end, clean them up, do a iso clean of the slot, dry it out, test some continuities, seems ok, reassemble, no change - check continuities on some IC's I reflowed (UE8 for instance), all good There are other paths I can go down, but I have a question: what is the likelihood that the PSU or ab recap could be the cause of this? It's the only thing that changed from a working SE/30 to now. I'm going to wash the mb one more time to be sure, but it WAS working before now, so I'm unsure. I know coincidences are more common that I'd like, but it's not the first place to be looking... so... thoughts? The only possibly weird thing I'm noticing is a series of about 8 very faint clicks coming from either the ab or psu a few seconds after power on... I'm not sure if that's normal or not.
  4. Hi there, Recently, I picked up two SE/30 boards to repair. So far, I’ve been having trouble repairing them as both seem to have Simasimac even after cleaning and recapping them. One of the boards has the early stages (artifacts across screen) with death chimes while the other one has zebra bars and no chimes whatsoever. Both persist even when ROM and RAM are pulled out, both have no batteries, and both persist after resetting (both power and buttons on board) What steps should I take next?

    SCSI problem.

    After finally getting around to looking at my second SE/30 and its SCSI problem I think I need a second opinion: The machine is fully recapped and other than the SCSI issue works perfectly. Symptoms: SCSI disks are seen but any filesystem found on the device gives an error "Invalid name". Initialisation hangs and then times out. I've buzzed out all the SCSI lines and the system data lines and they seem fine. Using an oscilloscope I can see data transfer on every SCSI data line. I'm using a known good SCSI device which works on other systems. All the PCB tracks look fine, as you can see from the attached image. So, I'm guessing that the issue is with a bad NCR53C80 SCSI chip?
  6. Folks, let me be clear. MacEffects is worthy of your consideration.
  7. All – I'm genuinely flummoxed by this. Have any of y'all seen this happen before? I took a working, recapped SE/30 without a PRAM battery, installed a new PRAM battery off Amazon, and boom – simasimac on boot, no chime, even after waiting for RAM check to complete. Removed the PRAM battery, and I'm stuck with the same simasimac. Would y'all know what might have happened here, or how inserting a PRAM battery in an SE/30 that previously worked might lead to a simasimac? To make sure I hadn't accidentally unseated a ROM or RAM SIMM, I removed all of the SIMMs, soaked them and the logic board in vinegar to get rid of any corrosion, washed it, and dried it. No change. Attached are shots of the top and bottom of the logic board, if that would help. They're a little blurry. (Some IPA is still trying on the top shot, so it looks a little bit wet.)

    SE/30 internal HDD termination

    Hello everyone! I have a SE/30 that boots from the internal HDD only if a ZIP drive is connected. I initially thought it may have something to do with bad traces on the motherboard (and still haven't checked since it is not my area of expertise), but then I remembered: the HDD is a Seagate 8GB drive taken from an external Lacie enclosure. Is it possible that I have to terminate it with the switches present on the HDD? I found the manual for the drive but I am unsure on how to proceed. Maybe it has nothing to do with this, but the jumper plug on J2 is set to "term power from drive". Should I set it to "terminator enable", another setting or leave it as it is? Mine is the "N" model. Thanks.

    IIgs keyboard not working at all!

    Hi everyone! After some time searching for one, I Irecently bought an Apple IIgs keyboard for my SE/30 (the seller lives just 2 km from here, what a coincidence!). It is quite yellowed but the keys are quite nice and not sticky. I plugged it to a SE/30 with a cord taken from a working AEK II but nothing happens. It appears to be totally dead. Either port doesn't seem to work. Am I missing something? Even the PCB doesn't appear to be too terrible. I really wouldn't want to resell it or buy another one - they are too hard to find and import to Italy.
  10. I've been working on a new video focused on SE and SE/30 fan upgrades over the last month and a half. I don't have any machines with the old squirrel cage fan, but I am aware many SE owners are. I want to add info in my video for those folks. I've searched this forum for "squirrel cage" and read through a lot of posts, but no one has provided a step-by-step upgrade with photos. Uniserver said that in his opinion it was the best fan because it moves a lot of air and is quiet, although he admits that it's noisy when dirty; and the reality is fans get dirty faster than you think. The boxer fans in contrast remain about the same in volume even with a bit of crud on them. Plus, the boxer fans are sold today whereas the squirrel cage fan is not. Anyway, I want to confirm with those of you who have done this squirrel-to-boxer fan upgrade how you did it. Specifically, if all you have is an older SE analog board with the squirrel cage fan, removing that fan means you have no metal bracket for mounting a replacement 60mm fan. (Newer analog boards had 60mm boxer fans.) I did find the following post: But "Velcro"? Really? Seems like it would wobble around after a while. In any case, I'd love to see a photo of that. Another post I found was this: But that is only for a 50x20mm fan, which I personally would not use because it's too small. Even most 60mm fans are rather small in terms of their airflow. Anything smaller would either not move much air at all or need to ramp up the rpms and be noisy to move sufficient air. If anyone knows of someone who created a 3D printable bracket, that would perhaps be the ideal solution. It might a bit more sound damping too as compared to the stock metal bracket, but one would need to print and test such a plastic bracket to know for certain. Any thoughts, suggestions and photos you are willing to share would be appreciated. Thank you.

    CC and SE30 damaged pads

    Destroyed a few pads on my CC and SE/30 boards. CC was the first board I tried to re-cap, with my rusty soldering skills and not the best iron. My electronics guru helped reconstruct most of the traces but we couldn't get this last one and I can't tell what it connects to. SE/30 recap went smoothly (I learned from my mistakes with the CC and took it slow) but I broke a pin off UF8 and then killed 4 traces trying to remove it!
  12. Just this christmas I got a macintosh se/30. I did a recap on it to bring back the sound and to bring back the occasional boot issues with the internal scsi. The internal scsi boots fine now no matter what, but neither my external scsi or external floppy ports boot. The machine starts up and when any external sources is in it gives the flashing floppy. Now I know its not the floppy since Its a emu and it works on my se and my plus. And I know its not my external scsi because It works fine when I use it on my other machines and it works when I put it in the machine. And yes there isn't the slightest of corrosion on the board, I was so surprised to see it in such good condition inside. I have cleaned both the ram slots and the ram. I also cleaned the slot for the rom and the rom itself. It boots fine with an internal but not external. It sees its there because it freezes at boot up to try and boot from the sources but it just wont from either.

    Mac SE/30 no video after re-cap

    Finally got around to re-capping my Mac SE/30 board, after swapping the CRT from an unhappy Mac Plus and confirming signs of life. Screen came on and I could even boot off my Floppy Emu, though sadly the ADB ports appear to be dead. I knew it could use a re-cap after 30 years (at least 15 of which it was used as a door stop at my old high school). Re-cap went smoothly, and afterwards I cleaned the board with soap and a toothbrush, pressure washed with hot water, then shook and sat to dry overnight. Powered on the next day and I get a chime but no video. I decided to have a go at re-flowing UE8, UF8 and the other chips in that row, along with all the caps I had replaced (a few weren't as flat as they could be). Powered on and not even a chime. Went back for a second pass and ended up breaking a leg off UF8. The speaker chimes again but then blip-blips indefinitely, almost like it's stuck in a reboot loop but doesn't fully chime after the first one.

    Assigning SCSI chains

    hi guys, I’m looking to daisy chain SCSI peripherals to my SE/30, i’ve not done this before and could do with some advise as i notice some of the peripherals require assigning a scsi daisy chain number others don’t, i have the following:- -Zip100 no scsi assignment number -AVID external HHD has assignment number. -Apple 300 CD-ROM has assignment number. -None branded CD-ROM no assignment number. -UMAX Astra 610 Flatbed scanner also has assignment number. i would like to set up the daisy chain to my SE/30 so questions are: 1.) do i have to set them up in any kind of priority order, ie those with auto numbering first or hhd first 2.) do i need to have them in order of the chain ie if say the avid hhd is first link in chain that must be 1 i know the last in chain requires a terminator which is fine as i have one. any advice of setup would be most helpful. thanks Neal
  15. Just as the topic asks, has anyone tried using a rounded scsi cable for their SCSI2SD or even just normal internal scsi hdd? I don't love the idea of twisting the flat cable to orientate it correctly in my SE/30. I remember in the past buying roudned IDE cables but I'm having trouble finding SCSI. Any thought or advice?
  16. Hi folks, this is my first post here and I’m looking for some help diagnosing yet another video issue with a Mac SE/30 - hoping that someone could point me in the right direction. Usual story, dug the Mac out of storage to find it didn’t boot, display full of stripes and noise. Removed the caps, cleaned out the electrolyte, dirt and oxide, replaced caps. The board looks great, no visible broken traces and squeaky clean. Connected to power, the Mac chimes, POSTs and boots all the way to the Finder normally, the mouse and floppy work. The issue is only the left quarter of the screen is being drawn, as if divided into four columns, leaving horizontal strips across the rest. In the Finder I can make out the trash and menubar but being continually overwritten in the same quarter screen. It’s as if only 25% the VRAM is being written, but the whole memory is being read back out to the video circuit. With the RAM and ROM SIMMs out the Mac shows a stable full screen stripe pattern. Swapping out both RAM/ROM with a known good set yields the same results. I’d appreciate it if anyone could offer any advice on what could be happening. Before I buzz out the entire board or start replacing chips I’d like an idea of what’s going on.
  17. Hello, My Macintosh SE/30 motherboard has been having issues since I received the computer in mid July. First of all, it used to turn on and do the simasimac, and death chimes but then I sent it out to MacCaps, and he tried to repair to no avail. It did the same thing when I got it back, so I tried washing the board in 5% White vinegar, but that didn't do anything. Any suggestions? Thanks! -Ryan
  18. Hi everyone. I'm not English speaker so maybe I can't tell about some problems nicely. sorry about it. Few days ago I bought Macintosh SE/30 with no HDD. it looked some leaking capacitors on the motherboard, so I remove capacitors and then clean the motherboard with dishwasher and dry it out and then recapped. Then boot up SE/30, it looked boot up nicely. She can boot up from internal FDD and external FDD(Floppy Emu). When turn on the power, internal HDD looks spin up and can see blinking access LED. But can't boot up from HDD and can't see from Finder. I try format HDD on some third party formatter software but they can't format. They looks recognize the HDD but can't do any functions. When try check SCSI devices on Lido 7, it says "OSErr= 5 bad scsi command: phase error." on SCSI ID 0. and Pmount shows 0MB Drive on SCSI ID 0. This also happens another 3 HDDs I have. What I can do for fix this problem? Thanks IMG_0614.HEIC

    Mac SE/30 network problems

    Hello everyone! I recently acquired a CNET technology cn470e PDS card, which I installed some days ago. I wrote another post about it, but unfortunately no-one replied (https://68kmla.org/forums/index.php?/topic/57586-se30-cnet-network-card/). Probably the post is too dense and full of useless things... . I am trying to surf the internet with the SE/30, but I am completely stuck. I installed OT 1.3 and AppleShare 3.7.4, Netscape 2.02 and iCab 2.99 (freezes at startup). The red LED is on (connection is good) but the greed LED is off (data being transmitted). What do I do from here? Any help is greatly appreciated! Thanks a lot.

    SE/30 startup problems

    Hello everyone! My SE/30 has always had a weird problem: if I boot from the internal hard disk, most of the time the system software doesn't load, and the floppy icon appears (as if the HDD took to long to spin). This happens almost every time, maybe it will boot once every 20 times or more, and mostly at cold boot. But if I connect a SCSI Zip drive (even without a cartridge), the Mac boots just fine to System 7.5.5. I have a 8gb hard drive with five partitions, the system folder is in partition 1. Otherwise it's a stock SE/30 that needs recapping (no sound). RAM is 8mb. Anyone knows why this happens? Thanks a lot!

    SE/30 CNET network card

    Hello everyone! I hope this is the right place to post this, if not so then I'll remove the post. Some weeks ago I acquired on eBay a PDS network card for my SE/30: it's a CNET Technology CN470E card. Just today I found some time to install it, and TattleTech indeed confirmed some stats about this card: Now, as I have never used network cards before, I would like to know if some you could help me in configuring it and try surfing the web/share files/email, etc. There is an older topic on the forum about this card (https://68kmla.org/forums/index.php?/topic/55066-anyone-able-to-identify-this-se30-network-card/&tab=comments#comment-584140), but it wasn't completely solved and I hope the drivers included with system 7 are good enough. I have also read the pinned guide to connect the SE/30 to the web, but it confused me quite a bit. I also have lots of (probably) unnecessary things in my system folder. Maybe some of you could tell me if I can delete some control panels/extensions and replace them with more efficient ones. I know it's a real mess, but somehow I feel most of those things are not needed for what I intend to do. I don't have many ways to transfer files to the SE/30: I only have a SCSI Zip drive and a USB Zip drive for my modern PC and Mac. Also: do I need a particular router? A particular Ethernet cable? I'm totally new about this. Thanks a lot! P.S. what does the little lever (on the right side of the card) do?
  22. I have a fully recapped SE/30 with 128MB RAM, ROMinator II Mega (with stock software still on it), and I'm booting from a FloppyEMU in HD20 mode. Even though FloppyEMU is basically a floppy emulator that connects to Macs via the floppy port, "HD20 mode" allows me to create a disk image (in my case, just over 200MB) on the SD card of the FloppyEMU and boot from it, just as an Apple HD20 hard disk would boot (via the floppy port). Normally the SE/30 cannot boot from an HD20, but the ROMinator II fixes that problem and allows booting from the FloppyEMU in HD20 mode and even from a real HD20. Currently, I am using System 6.0.8 on my FloppyEMU. Everything works fine and as expected EXCEPT for MultiFinder. For some reason I don't understand, MultiFinder won't load when I boot System 6 from my FloppyEMU in HD20 mode. (You always know when MultiFinder loads because you can see a little icon in the upper right of the menubar. When MultiFinder doesn't load, as in my case, that icon is missing.) No matter what I do, I can't get MultiFinder to load when booting from the FloppyEMU in HD20 mode. Yet if I boot from a spinning platter HDD (external SCSI drive) into System 6.0.8, MultiFinder loads just fine. I've tried copying MultiFinder from my HDD to my FloppyEMU without success, and I've tried a fresh copy of MultiFinder from System 6.0.8 install disks too, which doesn't work either. (I am booting in 24-bit addressing mode.) Those of you who have both a ROMinator II and FloppyEMU in HD20 mode booting System 6, have you experienced this problem with MultiFinder?
  23. I've had several PhoneNet adapters in my collection for many years but never used them since my SE/30 has an Ethernet card. But today I was thinking about multiplayer games like MazeWars which might be fun for myself and my two kids. I have a Mac 512k (64k ROMs) and a PhoneNet adapter for it (including terminating resistor), and I also have two Farallon PhoneNet adapters with round connectors for use with more modern Compact Macs like the SE/30 shown here: I am running System 6.0.8 and System 7.1 and 7.5.5 on my two SE/30's, and I have pre-System6 operating systems on floppies for my Mac512 (again, which has the original 64k ROMs, not the newer 128k ROMs of the Mac 512kE or Plus). Since I've never used PhoneNet before, I have the following questions: 1. Can one even play games like MazeWars across different Macs and operating systems? (A Mac 512k is quite different from an SE/30 in terms of floppy disk drive capacity, ROM, RAM and OS compatibility.) 2. What specific software must I have installed on System 6.0.8, System 7.1 and pre-System6 Macs? And, is there a minimum System version for this to work? (Is use of a 400k boot floppy out of the question?) 3. Can I use regular telephone wire? (The kind of wire you'd use to connect a wired phone to a wall socket?) 4. Say I have my Mac512 and both SE/30's all connected via the PhoneNet adapters, and say I have all the required software installed. Now let's say I sit down at the Mac512. I assume I will see both SE/30's in the Chooser? And do I select both SE/30's in the Chooser to start networking with them? 5. Will this LocalTalk setup work with pretty much any multi-player networked Mac game? Thanks. P.S. Yes, I am aware of the Definitive Guide to Networking, but it doesn't answer my questions specifically. Indeed, answers to my questions above may become the new definitive guide since they don't seem to be answered briefly and specifically elsewhere.
  24. Question for those of you SE/30 owners who use a PDS video card with an external display. I have a Micron Xceed video card and grayscale setup. Grayscale works great on the internal CRT, but I've never used the DB-15 port also offered by the video card. I have a 15" Color VGA LCD that's about 10 years old. Would this adapter on Amazon be all that I would need? (Not sure how those DIP switches on the adapter are used in case like this though.) Note the horizontal scan rate mentioned in the Xceed manual page below of 31.5kHz, which seems rather odd (maybe common for Apple though?). Any thoughts would be appreciated. Thanks.

    SE/30 burnt ROM socket

    I was in the process of cleaning and recapping an SE/30 logic board which had been subjected to a battery leakage. I've checked and rerouted all the rotted traces (totalling about 15) between the RAM, ROM, VROM and GLU but when I was satisfied enough to attempt a boot, pin 63 on the ROM burnt out (causing pin 64 to fall off, but pin 63 was definitely the offender) leaving me with a dead SE/30. Any ideas what might have caused the sudden burning on the ROM? I've checked it in another machine and now it only boots a grey screen with death chimes. Maybe there is a short I haven't noticed, or there are broken internal traces too? Any suggestions are much appreciated, but I fear this machine is un-repairable.
