PSU is a refurb I purchases as initially I thought it was faulty. As I have no idea how to test the onboard capacitors I will have to replace them all. oof

Surface mount caps can leak from underneath and sometimes you wont see the goo until you remove them. Capacitors inside the PSU itself are probably due for replacement anyway.

No luck even after the MC68030 which was 'borrowed' from a working Mac.

So, I've recently discovered that Carnegie Mellon's computer club owns a Lisa 2/10 (unfortunately with Mac XL mods). I'm trying to get this machine operable again, but we want to …

From my notes: The IIfx introduced a new implementation of Mac SCSI that was faster than previous versions. Unfortunately, IIfx SCSI introduced a set of quirks that are unique to …

The 550 board is, if I recall, identical to the Color Classic II and is easily swappable. Keep in mind the 520 and 550 use the 68030; the machines mentioned in the original post al…

I think that terminator was to fix noise problems, terminate the SCSI chain like you normally would for any other mac.

Having never owned one (until now) I am not sure exactly how the SCSI on the IIFX is different other than the black SCSI terminator. The unit I got (free) has the IIFX, 3 video ca…

It originally had a 68030/16 so any 68030 should work when installed.

Memory slot tabs are broken and RAM is held in place with little bit of dough (i think) I will try to remove ALL ram one pair to see if the helps and will add CPU directly to boar…

What is that crud by the RAM (dust or did somebody break off the retaining tabs and glue the RAM in)? Also looks like you might have RAM that isn't matched in one bank. Try remov…

Can you take a decent picture of the motherboard with cards removed?

ROMM SIMM installed. Power switch in the back (and ones on the side) all click. No idea how to check capacitors

Does it contain a stock SE motherboard Click to expand... No. The Dynamac went down that path, apparently, and used my favourite retro display tech - electroluminescent. http…

If you're looking to use a 500 series without a monitor, you may also want to consider the 580, which uses IDE drives instead of the less common, pricier SCSI. The monitor on the 5…

Well, it was like this since I got it. It might be that, I don't know. I don't even know if it's worth saving, as the CD-ROM drive is dead and the floppy drive has a disk stuck in…

The initial surge of current may be too much to power on the AC adapter without a battery installed. The battery can dump a lot more current for short-term things like spinning up…

You could always put a video card in the 575. You'd have to set it up so that it always defaulted to this card but it just might work (I've done this on an LCII with a Radius card …

Hey Mars, What vintage is that iMac G5? If it's some of the early models prior to mid-2005, it may be the internal power supply unit. If so, check to see if Apple still covers i…
