Its a good thing you have a large collection, cause you seem to be the bringer of death ... can you get to the main board of the mac, if so sniff around up close (like practicall…

PMed ya.

It's not too, too rare, actually. My Macintosh LC 475 also has the ROM SIMM socket (along with a red PRAM reset button) too.

I'm still kicking myself I didn't bid for the CAMMjet I sold for work last year. /ouch /ouch /ouch Click to expand... Ouch! But if you wanna REALLY feel bad, just ask me how mu…

I"m just curious...what kind of floppy drive does it have? Does it have the older auto-inject floppy drive, or the newer manual inject floppy drive? Just curious, because I know th…

While Working on my powerBook 150 today, I got it to a almost perfect condition. Put it back together and, a Black screen and a bad smell. On further inspection it seems that I hav…

No it needs to match the CPU's clock speed, so it should be a 25 not 16 like that one is. Also don't expect a big performance boost from it.

so something like http://cgi.ebay.com/Motorola-MC68882-68882-co-processor-FPU-cpu-MC68882FN16_W0QQitemZ220347416031QQcmdZViewItemQQptZLH_DefaultDomain_0?hash=item334dbabddf&amp…

OK... if i want to add an FPU, what should I search for on eBay? Click to expand... 68882

OK... if i want to add an FPU, what should I search for on eBay?

I cannot imagine that it´s a prototype, because it was used by a big press agency here in Austria. On the other hand this could make it possible that it´s an verry early machine. T…

The LC III shouldn't be picky on the type of RAM, as long as it's a 72-pin SIMM and isn't ECC. However, I believe that the only type of VRAM you can use is one that is marked "LC …

Nice. I keep track of a few websites in the hope of getting lucky someday.

Analog board checks out, so my repair there was a success. Unfortunately the logic board is toast... me and Wackymacs on IRC, with his copy of Larry Pina's book handy, were unab…

It seems like the seller was having some work done on his house, so he was clearing out old stuff he no longer needs. These items had been in storage for years. It was just a local…

And thus dies my idle thought of a 700MHz transplant ...

Have you done an in-depth study of where hot air stagnates inside the case? Click to expand... Can't say that I have. In brief, air flows in under the HD at front-left, and ou…

Hi Nick - how goes it Just to confirm: - iMac slot-loading 350 - 500Mhz (ceramic CPU) have interchangable logic boards - iMac slot-loading 500Mhz - 700Mhz (IBM 750CXE G3) aka…

This throws me a bit ... are you saying the FDD continually spins up and down? But if you remove the logic board, how can the sound continue if the FDD is no longer connected? If …

Yeah, its for a ROM SIMM. All LC475's have those solder pads for it, but I've never seen an LC475 with the actual slot, I'd say that as Gil said, it may have only been in prototype…

what kind of ram/vram? IE: 72 pin 45v blah blah blah SIMMM
