  1. I will be curious to see what happens... I have mine in a LC550 with OS 7.5.5 and way more than 8MB RAM and it works fine although as noted I do have to turn 32 bit addressing off when using the card. It will request that I do so before the software will run IIRC. That's a totally different animal than your 575 though. I always kinda thought LC and LCII were the perfect homes for these cards, especially with minimal RAM and very small hard drives commonly found in them, and system 6.0.8L.
  2. So with that Rev. A ROM... how is your IDE set up? Rev A is limited to one device per channel... I see you mentioned a hard drive, Zip, and CD-ROM... if you haven't already tried this, remove the Zip drive from the equation and have your HD and CD-ROM on separate channels. I don't remember what the jumper settings need to be, single or master may be the safest. Beige G3s often had SCSI PCI cards and hard drives installed when they had both a CD-ROM and Zip, at least from what I've seen. Both of my towers had Rev A ROMs, IDE CD drives, and 4GB SCSI hard drives, although they were
  3. What happens if you hold the shift key while booting to disable extensions? Will it complete a boot then? Might also try initializing the drive using Drive Setup and update the drivers on the drive as well.
  4. I have not been able to get anything larger than 32MB to work at all on my DOS card. I've experimented pretty thoroughly with that... any module smaller than 32MB works fine, nothing larger works at all or is only recognized as 32MB. Seems like a pretty hard limit but I don't have any single sided modules larger than 32MB - in any case, 32MB for the DOS side is way more than enough. I have also not been able to get anything larger than 16MB to work in the second slot in the motherboard but if I remember right it was an issue of using single sided SIMMs in that slot........ IIRC m
  5. I did the full '040 and overclock mod on mine and it has been working perfectly for several years now. I did add a 468 heatsink and fan to the '040 chip - I think that's a must. Huge improvement, I have no regrets and the DOS card seems to be unaffected. Seems like I also upgraded the 486 chip in mine as well, don't quite remember though, that happened close to 20 years ago now. FYI the published max RAM limit in these is not totally accurate. I have 148MB in mine. I thought it was 52MB for the longest time, as is published, but I ran across a 64MB stick that worked
  6. I have also done many boards with 16v caps. Zero failures that I can attribute to the components themselves - plenty that are directly my fault but that's another topic. I'm curious if there is a true risk in doing this... what is the exact time before failure can occur? Are we talking hours? Hundreds of hours? Depends? I imagine most of us probably have our old computers powered on a minimal amount of time... I'd be shocked if any of mine see more than 5 or 10 hours of use per year. I hate to admit but most maybe get powered on for a few minutes and then put away for long pe
  7. Just the upgrade to a color screen could make it worthwhile but it depends what you're using it for. A Color Classic has been near the top of my want list for as long as I've been a Mac user... one just hasn't shown up locally. Realistically though, for me, my LC550 fills that hole and then some since it has a CD-ROM drive and is capable of higher screen resolutions, and takes up a minimal amount more space comparatively. The CC just has that cool compact Mac feeling. I don't know what availability is like in Europe but I would expect $500 to be a "fair" price (in 2020 terms) to
  8. So I tried DVI... and it defaults to 1920x1200. Great! However... it does not work well. Sometimes I get a distorted, static colored section on the right side and some programs that attempt to switch resolutions or screen colors crash hard and lock up the whole machine. Some others make the screen flicker on and off. Very odd problems that I never had previously... I am not sure if it's a video card issue, a driver issue, or a monitor issue, or some combination but I'm going to give up on it for now. I guess I will just have to be happy with my old 19" Trinitron CRT.
  9. I ran across a Soyo 24" LCD monitor a while back and finally got it fixed (bad cap in the power supply) and it would sure be cool to use it with my beige G3. I got it all hooked up last night and have discovered that I cannot get it to display the native resolution (1920x1200.) It will display most others up to and including 1600x1200. Some result in a message on the monitor saying "out of range." If I choose "All" in the Monitors control panel, I actually get some choices higher than 1920x1200 but not that one specifically. Is there a way to custom add that one or am I out of luck?
  10. Have you moved the video card to a different PCI slot? Kinda sounds like a video card failure... do you have another one you could replace it with? I'm assuming you've tested the monitor with a different computer and it works fine there? PRAM battery is not required for it to boot.
  11. These are in somewhat rough condition so I figured I'd risk it... They were very dirty and had leaves, dead bugs, etc all over them. I don't think water alone would have cut it. I really rinsed them and blew the excess liquid off with compressed air. In any case, I recapped LC board #2 this evening. It appears to be working great! Looking forward to the LCII next.
  12. I washed the other three boards with dish soap and water, rinsed with distilled water and flushed with denatured alcohol last night. Took them into my lair and recapped one of the LC boards - works great now! Maybe this weekend I'll have time to recap the other two and wash the first one. Hopefully I can get the three dead hard drives to at least spin up and work temporarily... it's always kind of interesting to see what's on them. The working one appears to have been used in a computer lab.
  13. Well... good news! I was quite surprised that all four of these fired right up. Three power supplies were dead, two hard drives spin up and then spin down, one won't spin at all, one works fine. All of the logic boards have some rust on/around the output ports and all are filthy and need to be recapped. I have one good LC lid, one good LC bottom, one good LCII bottom... the rest of the cases are broken in some way unfortunately. I recapped the best looking LCII board last night and while it works, I have no sound for some reason. Maybe will try washing it and see if that helps
  14. I keep thinking I'm done, I'll never score anything again, it's all over... and then I run across something cool. First score was actually like a few months ago, I picked up a IIcx, a couple small Apple monitors and some peripherals, all unknown condition for 10 bucks. IIcx was DOA, battery dead, caps leaked everywhere. Recapped, cleaned it up, converted to CR2032 battery and it works great! Even came with 32MB RAM and an ethernet card. Second score was yesterday/today. Found a Facebook ad for "free old TVs" and spotted a 12" pizza box monitor so I went and grabbed
  15. I can't imagine why it would be worth making 4MB SIMMs. Even 16MB SIMMs are not *that* expensive, relative to what a lot of us spend on this hobby. 4x4MB sticks are readily available on eBay for less than $30... not worth the hassle to roll your own. It is a cool project though and certainly worthwhile for RAM that is not available or just uncommon - IIfx memory for example.
  16. It would be a shame to trash the logic boards in those, especially since they can be used with ATX power supplies. The cases I can understand, I have pitched a lot that were falling apart too. These were just such nice machines and great for hackintosh purposes. They were also not known for capacitor failure, those ceramic caps you're seeing may be factory equipment. Beige G3's won't boot with the personality card (sound card) removed by the way...they will appear to be DOA if that piece is missing.
  17. I have had dozens of pizza box LCs of every variant over the years - the ONLY one that has a PRAM battery quirk is the 475. Turn it on, wait for the chime, flip it off and back on again quickly and you're good to go. NONE have done anything past simply not holding the date/time/etc. None. I would suspect a flaky power supply or capacitor electrolyte damage on ANY LC/II/III/III+ that doesn't go straight to video when powered on.
  18. Hahaha.... this thread is awesome. I have had one of these monitors sitting in my garden shed for several years now. It's been holding up a pile of gas cans and a bag of concrete mix Had no idea they were worth anything or that they were desirable. I was going to use it for a home security system monitor. Maybe I'll dig it out and see if it still works - pretty sure I dug it out of the trash, plugged it in once, and stacked things on top of it.
  19. LC/LCIIs deserve the criticism they get - even with period correct software, they are slow. But I guess they really served as a glorified word processor in most cases... I just remember being shocked when I walked into 9th grade computer class in 2001 and saw a lab of LCIIs networked together by PhoneNet adapters. That was three years after 6th grade keyboarding class where we used (relatively) lightning fast 386 and 486 based IBM and Compaq machines!!! To add another layer of comedy to that, some of those IBM 386 machines were donated to the school by a local bank. Thinking bac
  20. Hit up an estate sale today. Lots of boxes and buckets of stuff - some really nice stuff (Snap-on wrenches, etc) mixed in with old screws, sheetrock tape, etc.) Looked like an organized garage dumped into buckets. Anyway. I spied one red toolbox that I had to look in, and immediately shut it and took it. Appeared to be full of soldering stuff, figured what the hell... it was $20. Get it back to my office along with a lot of other crap that I couldn't resist and dug through it. I knew there was a soldering iron or two but didn't realize there was this:
  21. If I was dealing with broken clips I'd be real tempted to hot glue the RAM sticks in place. Just a little dab on both ends would hold it and it's 100% removable, and a LOT easier and safer than replacing the connectors.
  22. My 512k was upgraded to Plus specs, I'd probably undo that if I ran across a 512k board/400k drive but it's just parts swapping at that point. I don't know if I'd go as far as undoing permanent upgrades just to downgrade... what's done is done is my MO.
  23. Long time before POST is normal, especially if you've got a decent amount of memory installed... it's just performing a memory check. Mine take forever; they have 768MB. If you don't want to wait, you can hit Command, Control, Power right after the chime and it will skip the memory check. See these two posts about those messages you're getting... it's the open firmware prompt. Usually you never see that and don't need to mess with it unless you're installing OS X. http://hints.macworld.com/article.php?story=20031208155258818 https://lowendmac.com/2012/how
  24. You should be able to use any ROM version on any board...it is really only relevant to the IDE bus. Maybe see what your jumpers are set to on the CD and HDD... IDE is very simple... you can do master, slave, or cable select, with a maximum of two devices per channel normally but only one per channel with a revision A ROM. You can have master/slave, slave/master, cs/cs but NOT master/master, slave/slave. I think you have to use cable select with rev A ROMs... seems like it gets confused if you set it to master or slave IIRC.
  25. What does your IDE setup look like? Single drives per channel or multiple? What ROM revision do you have? I'm assuming you don't have any SCSI devices installed in the system? Rev A ROMs are limited to one IDE device per channel... B and C are not. These things are really reliable, well designed machines but they have a few quirks.
