  1. Hello, I want to upgrade the memory in my SE/30. Has anyone purchased 16MB SIMMs from the company Memory(X) ? thanks Rick
  2. Troubleshooting an SE/30 motherboard with an oscope is almost impossible with how short the power/signal cable is (J12). Has anyone tried making a longer cable for troubleshooting? This is the cable that connects the motherboard to the analog board. thank you, Rick
  3. Hello everyone, I thought I'd start a thread on my own SE/30 repair experience both to document what I did for others and to solicit some advice on a few stubborn issues I can't resolve. I picked up a nice-condition SE/30 from Craigslist that was listed as "something's wrong with it". It turned out to be externally in great condition. It is a later unit (manufactured in 91 I believe) with the Astec power supply, original hard drive, and 4 1MB sticks of RAM. When I got it home I powered it on to a muffled, indecipherable sound and classic somasimac screen. There was no hard disk activity
  4. Hello I am doing a complete cleanup and visual inspection before I go through repairing the logic board. Anyway, I noticed that once I removed the anode cap a red sticky material was found on the anode cap and the anode aperture. I wonder what this material is, I imagine it is there to act as a glue to keep the cap in place, or at least help it stay in place. I am wondering if anyone has more info and whether this material is critical if so, I have wiped some off when it occurred to me that it is likely needed. I would truly appreciate any information. Kind regards —A
  5. 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 f
  6. I just got a Macintosh SE/30 a few days ago and want to do an LCD conversion with original hardware (none of that silly Raspberry Pi or Mac Mini board business). CRT is damaged, so perfect excuse for a fun project (hopefully I don't eat those words). I would imagine this type of mod involves pairing the right screen and card together (computer came with a Radius FPDSE30 if that helps at all).
  7. 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. C
  8. I made a new walkthrough video about replacing all the electrolytic capacitors on the MicroMac DiiMO 50MHz 68030 accelerator for the SE/30. I explain my choice of Niobium Oxide capacitors over tantalum, show the replacement, then boot and run benchmarks. The SE/30 shown has a recapped motherboard, recapped analog board, and SEASONIC PSU. The video is 4K but if you're a Mac user who loves Safari, you'll need Chrome to view it in 1440p or 4K. Also, it was sadly during the making of this video that my Epic Blunder occurred. My humble thanks to all of you who are so kindly trying to help me in
  9. Hi, I searched but couldn't find this info so I'm asking here. The RAM chips on my logic board seem stuck. Is there something special about removing them (and the ROM)? Hmm after review, I see I should have put this in the lounge. Sorry.
  10. Hi all, having problems installing rominator 2 and owc memory. tried installing both separately without sucess as i just get a grey corrupt screen on boot up and funny sound. I cleaned up the board and connectors with contact cleaner as i thought maybe my se/30 is afterall 27+ Years old and may not have had the simms installed/removed in that time but still no look, put the old rom and ram back in and it worked straight away. Now i have a new 1gb hdd with Mac os 7.5.5 installed and wasn’t sure if that was causing the rominator from working but as i cant even get a boot up screen that
  11. Hi, I got a dead SE/30: no boing but short rustle from the speaker, black screen, no sound from floppy, SCSI2SD board blinks once, when the Mac is switched on. That's all. I've read "The dead Mac scrolls" and more and these books told me about a bad analog board when getting a black screen. More failures may come, when I get a working screen... So I bought a (working ! ?) analog board / power supply from ebay and replaced the old board and power supply. Same problem now. Could this failure be on the video board or logic board as well? Hope you can help me.
  12. Hi all, I received a dead SE/30 that I’m trying to bring back to live. When I first switched it on it started without a chime and on screen was just a vertical line. To fix the audio I did a manual cleaning and re-cap of the logic board. For the vertical line I read that it’s probably C15, however after changing that out I ran a smoke test and I heard a loud-ish squealing sound and I switched off the power supply. To test the logic board I figured I’d try a known good AB/power supply and it booted into the flashing question mark (yay), but after 10 or so sec
  13. I have this Mac SE/30 that was in pretty bad shape. I'm going to recap it hopefully soon. But after really looking close, I'm seeing this green "fuzz" all over the place. Pretty much every where a capacitor was, a nearby chip has the corrosion all over the pins. I'm really wondering if this board is a lost cause. I'm sure with enough time I could probably fix it. But some of those IC's look to be very hard to find. The worst example are UB10 and UB11 (Sony audio). But others are almost as bad including some of the VLSI chips. This is my only SE/30. I have three other
  14. Hey all, I know our friends over at BMOW have their rom module for sale at 2mb and there's one on ebay thats 1mb, but I have a design in progress for a 8MB (ish) simm that would allow for the installation for bigger ramdisks and the like. Throwing out a feeler here, anyone interested? OW ill probably just fab up some boards for my own use. (oh and buy BMOW's programmer because finding 72 simm slots is impossible )
  15. I just picked up a nice SE/30 and on boot I got this pattern. I swapped the board into my known working SE/30 and got the same pattern, so I know its not AB/power related. I'm assuming this pattern is typical for a board needing a recap, but want to confirm as I didn't see it on the repair SE/30 site. The board itself is clean with no cap leakage and a perfectly intact battery (Tadiran, not Maxell), but of course visual inspection can only say so much. Board image attached (and yes, I know the CPU isn't on it in the photo, it was when tested tho ) Thanks!
  16. I picked up an SE/30 with keyboard and mouse off kijiji today. The seller was a young guy, and wanted CAN$140 for the thing. The ad said it was upgraded with a 2GB and worked great. I noticed it had an Ethernet card and looked clean and in nice shape, so I decided to check it out. The guy said it was a gift and he had no use for it. After giving it a test run I bought it, and of course the first thing I did when I got home was open it up to check the condition and look for a maxwell bomb that might need diffusing. Not only did I find that it was beautiful and clean inside, it had been recappe
  17. Anyone have a copy of this software (Mac version)? i found an old dos version online but i think itd be cool on the SE30! I even tried contacting wolfram who said that version 1.2 is no longer supported. Really? its only released in 1989 about 10 releases ago...Id love to get the .img in mac form. maybe the dos version will work but i doubt it...ill try but just wondering anybody got a copy?

  21. I recently bought a Mac SE/30 which would boot from the Floppy and briefly from the SCSI drive after cleaning. But during a fresh install of System 7 the SCSI drive developed a fault and stopped being identified. The sound also didn't work at boot up. I recapped the logic board and the sound came back but the SCSI connection did not. So I decided to trace all the pins from the controller as recommended by many on these forums and found that 53C80 Pin 32 (I/O) failed a continuity check on SCSI (50-PIN) Pin 50 and DB-25 Pin 3. I have got this working by bridging the SCSI controller Pin 32 t
