    Tips for speeding up an SE

    Hey guys, hope the health is good. I'm using it as it is, slow and all, it don't matter that much now hehe I do have a potential Power Mac 7100 (IIRC) that is available locally, and I fixed the SCSI drive in my PowerBook 165C and it's up and running. One thing I was thinking is: If I'd get the SCSI2SD for the Power Mac (3.5") couldn't I also use it on the DB-25 external SCSI drive connector for the SE? Just switch SD cards. That would be "two flies in one hit". I'll send you a link when I'm done recording some new material, my dude.

    Tips for speeding up an SE

    Thanks a ton guys, did not know about that boot key combination! Excellent I finally had a proper test jam tonight, sequencing a bunch of hardware synths on the SE with a Opcode 3 interface and g’day the timing is good and funky! I’m so happy! ehm, I checked the RAM this evening and it is 4 MB hehe Saves me the hassle. The programs were originally written for the Classic/Plus/SE in ... uhm 1987? I also opened the program on a Performa (color, OS 7.5.3) and the program itself was/is actually in color... I haven’t seen an option in it to switch color modes. It runs fine on the SE (it’s perfect really). It’s just the damn redrawing of all windows that’s very slow. It has OS 6.0.3 on it. I’ll try booting it in the RAM mode and see if it helps, otherwise I’d think the way would be to create a RAM disk with the program on it and all files needed to run it and then just save projects onto the internal HDD. To fix the Miniscribe drive; I followed these instructions. note that he links to another video in the description, which is quite important for the fix I connected the drive to a baby AT power supply just to have it spin up, I did the process about 6 times or so, then I let it sit (on its side) for a good time, popped it in and made the computer run for a good amount of time just to get the lubrication into the shaft more thoroughly. I thought it was gonna be a hell of an operation (that black gooey tar leftover bumper with Quantum/Conner drives) but I was quite happy to find the MiniScribe inside, it’s quite a solid system, I like it! ps. I saved this computer from the junkyard and it had the original OS (in Icelandic) on it along with some files and programs from that Dept. maybe there are some stupid extensions or something slowing it down... I’ll check it tomorrow. I just don’t have enough DD floppy disks to do a fresh install. Plus the remnants of the past on this machine are quite “romantic” LOL

    Tips for speeding up an SE

    Hi Josh, thanks for the help! It is a SE with 1 MByte if RAM (I do have a huge collection of RAM chips, but getting the logic board out is a bit time consuming so I’ve let it wait.) The SE is indeed booting from the MiniScribe SCSI drive. Once the program is loaded up and all windows are visible/gathered that’s when I see slow redrawing (moving windows, clicking on some options which lead to other windows opening, etc.) The first on my list is to receive a SCSI2SD will be a 165C. I’m fine with the MiniScribe in the SE, as I only need to boot it, open one program and then work on that. Im general, I’m fine with old computers needing their time to calculate and compute. Just wondering if there are any tricks (or obvious things) that would make it snappier?

    Tips for speeding up an SE

    Hey guys, normally I search my ball$ off for the answers I need ...actually I talked to some of my buddies about this; search engines today have really taken a plunge (they used to be much more accurate a few years ago -I guess the web is bloated with stuff nowadays LOL) I haven't found any decent info on: A ) How to speed up a Macintosh Classic (I have an SE -OS 6) in regards of QuickDraw/Screen Drawing B ) How to set up and use a RAMDisk. I'm using UpBeat and Jam Factory on this lil' Mac I've been working on. I saved it from a dumpster, it's a government machine (it has a little metal tag on it; "Menntamálaráðuneytið" or "Dept. of School Education" (revived the MiniScribe drive with some beard/sewing machine oil the other day -hurrah!) The screen redrawing is über slow (compared to the ADHD mind of modern humans anyway) Do I need MaxRam and that other software to create a RAM disk? https://www.macintoshrepository.org/23044-maxram-maxprint Would it be faster to run the apps from said RAM disk? Any general tips to make it snappier? Thanks a ton in advance, -Geir
  5. I’d go for the IDE to CF route, I have one in a Performa, works like a pig. I have the “Chinese Connection” in my G4 PowerBook (white m.2 PATA/IDE box + cheap 32GB Chinese m.2 SSD) and that thing is VERY unstable, the system’s Node Tree gets corrupted every once in a while, requiring a fresh install....... The most solid I’ve come across; the Lindy IDE to SATA bridge, albeit a bit expensive it’s 100% solid, works like a champ and is backwards compatible all the way down to the late 80s = Ultra-ATA 33/66/133 to name a few.

    Macintosh Classic II Blues... :/

    Ah, thank you very much! That eases my mind, I had a Performa the other day that had a rather crusty CRT, I was on needles the entire time, just waiting for it to catch fire in the kitchen LOL

    Macintosh Classic II Blues... :/

    pheew! AC and CRTs are my least favorite. Just a quick glance; C14, what's going on there? F1 is that a fuse or an inductor? Also, isn't there a jumper somewhere on the board for the RAM configuration? Is it in the correct state? (I'm sorry, I repair synthesizers, just got a Macintosh SE yesterday at the junkyard, although I do have another one in storage, I've never worked on them per se)

    Scary, the last thing you see is him messing with the CRT of all things LOL just kidding, oscilloscope would really help!

    Performa Rehousing

    I took the 5260/120 apart, cleaned it out, sprayed the PSU and Analog Board with contact cleaner, tried my best to get all dust out of there.. I specifically remember my dad mentioning you need to "massage" the old brittle plastic, to loosen it up a bit, because this just snaps like a twig. I managed to get it apart without breaking anything :) So it's in really good condition and I just decided to fire it up (been what, 17 years? 17 years since I had a CRT monitor) so the memories were coming back; just leave it on for a good amount of time and I did. I heard a bunch of those snapping/spark sounds, old dust getting blasted by the Cathode Ray Tube arc? Left it on and it managed to boot all the way (into an Icelandic version, mind you) of OS 7.6 or 8.1 by the looks of it and voila! It's all good. The 5200/75 has a L2 Cache ROM/RAM? module installed, it's slower, but somehow I like it more, it's beat up sure, I'll need to 3D print some parts and shit-mix it a bit hehe, but I like it. It's easy to pop the CompactFlash card off out the back and both transfer files to it from a PowerBook and to back it up. It's a nice system to have for 7.5 duties, Serial Ports, nice CRT Monitor, logic board on rails and the HD being IDE and all :)
  10. *edit* I guess I was a bit tired, I had the Performa 5200CD System Restore disc, when I should be using the Performa 5200/75 one....... Seems to work, especially when I booted into the old IDE drives’ system and chose CD as the default boot device.
  11. What’s the dealio? I have a HFS formatted Performa 5200 Restore 7 and 7.5 CDs, burnt at slow speed. Neither computer wants to boot from it (four chimes downwards) BUT they both see the CD when I’m in the system (desktop) and I can browse and run the restore app. Holding C and cmd-alt-shift-delete: no dice. Does the SCSI drive only boot from sub-650 MB CDs?

    Performa Rehousing

    Hello  gang, new guy here. (lurker) I have a bunch of computers of all sorts (up to 20≈ish now LOL) I have a G4 at work doing some oddball stuff alongside a Mac Pro for all kinds of design and photography work. Got my hands on an old PowerBook 165C with all original documents and in mint condition, currently in the works (need a SCSI2SD for that one) Recently I've been on the prowl for an older Mac to use with MIDI Sequencing software. I've got an Opcode Serial/GeoPort MIDI Interface so I need a Mac that can run 7.5 - 8.5 circa and has that port. Rescued two Macintosh Performa machines from the junkyard yesterday, one is fairly beat-up (the plastic shell) but actually boots into 7.5.1 and is the working one out of the two; it's a 5200 and I've made a Disk Image clone of the hard drive (for easy installation onto a IDE -> CF card I'm adding tomorrow). The other one (5260/120) is in better shape physically (transplant?), I tried switching it on and the Cathode Ray Tube display is iffy to say the least, there's a small 'electrical discharge sound' and the screen flickers... I saw the Question Mark on the display before I switched it off. Albeit much dustier than the other one, I haven't cleaned it (might be dust?) These two suffered a concussion when thrown/semi laid into the electronics dumpster... So something's bound to be busted for sure. I've cleaned both Logic Boards and they look quite good. I don't mind the 5200 that actually works that it's a bit beat up hehe, I was thinking about getting my buddy to 3D print a new speaker grill for it (it's missing one) and some various bits and pieces. LOL -make it mine! Alright long-ass intro towards my question: Is it possible to house the "lower half" of a all-in-one Performa into a Mini ATX case? The computer/logic board itself is fairly small. I noticed in the service manual there is an external video port connector (so that would rule/free out the CRT) which could be utilized with a tiny LCD If it would be done, with a modern disk solution (IDE SSD or CF card - easily accessed externally) I'm not sure I'd need the floppy drive and CD drive, so it could even be smaller; basically just the logic board and power supply? *edit* -ah the power supply! Yeah I was thinking about the relation of the CRT display to the PSU in the Performa, how is that? I found this pin-out of an ATX PSU for a different Apple Computer /Performa http://www.mediafire.com/view/55x07ht4360wc0j/Performa 6200 - 6300 schema ATX.png# Thanks in advance, -Geir Helgi
