Depends on the type. What we typically see failing and leaking are electrolytic capacitors.

I have tried different RAM-configurations. The configuration "16 Mb in Bank A and 4 Mb in Bank B" and "4 Mb in Bank A and 16 Mb in Bank B" gives the same problem: - a black screen…

Just curious: What is the lifespan of a capacitor? How much do storage conditions matter in their lifespan? Just curious. My oldest machine at this point is a Classic II that appea…

I would call that "gunk" sitting to the back (under the chip) and in between those pins, rather than "corrosion." That gunk could consist of a variety of things, including leaked …

not enough to matter. ive gotten TVs running with corrosion on the main CPU thats MUCH worse than that. your problem is toasted caps. they all need replaced before further diagnosi…

Time to re-cell the battery pack!

And I always like the GS keyboard solely because it has "Control" in the right place. I never noticed that the keycaps are easy to move... Interesting. You learn something new e…

3.5" IDE hard drive, home-made SCSI cable, 2400 baud modem card and RAM card. { "lightbox_close": "Close", "lightbox_next": "Next", "lightbox_previous": "Previous"…

No, this is a third-party power adaptor. Unfortunately 2A is the maximum output, so when I'm at Fry's next I'll get a 3A. And mine has the case, and none of y'all can have it. The…

There was also the MFS/HFS thing. I know some software would not run under HFS, but could be remedied by running an MFS system, and/or keeping all files at root level. However ther…

'm using a 7.5V supply at 2A. Would that be sufficient, or should I go for a 3A one instead? Click to expand... 2A is what Apple lists as the power draw for the 5120. If it boo…

Nice work - this will be an awesome machine.

well ive never ran into one instance of software incompatibility except between 68k/powerpc, but thats a big duh on that part. hehe. it might have been mac128k or bunsen that may …

If you have the IIGS keyboard (my personal favorite and the one I use on my Classic), it's really easy to switch the caps--they will come off very easily with a very small flat scr…

And according to this document, 2-18, one of the MacCon cards (I seem to recall that I have one) had a removeable AUI daughter card on the connections board, making it possible to …

Mmm... Maybe I have make a mistake with that. I will try the SIMMs again and see wat happened. Regards, Emiel

I might take you up on that, depending on price, but according to an article on LowendMac on IIfx memory, "For 16 MB, install four 4 MB SIMMs in Bank A. To reach 20 MB, add four 1…

Well, that's got me thinking of what I might get up to one cold winter night next year....

I do, however, have a Mac II -> IIfx upgraded machine, so it is a IIfx in all but badge (and power supply, it seems), but as I have only 8MB of RAM in it, I have decided to …

I kind of like OS 7.1 best on a IIfx with 32MB of RAM, the lesser Mac II's can run OS 6.

Great story and the IIfx sounds a well-loved machine. I have a couple of 8600 604ev PowerMacs (at 300MHz) also, and think they are fabulous machines. I do, however, have a Mac II …

Why not just switch the key caps? Presumably you don't have to look at them if you're touch typing...

The IIgs keyboard and all IIe (not just enhanced) keyboards also have the bumps on D & K. IIe IIgs

I remember discussing this exact subject with a fellow Mac user back in seventh grade when ADB keyboards were in the process of being phased out. Apple's ADB keyboards had the bump…
