Nope. all that page told me was that i had Micron technoligy RAM.

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 …

I have a growing collection of olden Mac books too, including repair/reference/technical books and history books, as well as both John Sculley and Gil Amelio's autobiographies.

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

Mine has got a weird problem where the longer it is on, the brighter it gets. Within the first 20 minutes, one can compensate by turning down the brightness and contrast, but after…

Indeed. Partly, my collection is for posterity (if there will be a posterior). If they have the machines but don't know how to use them, then that's a shame. Not everything is docu…

Enjoy. Click to expand... Oh I am! It runs pretty much anything I run at it! Oh, and It is waaaaaaaay way faster than my 933Mhz G4. I know people say it lags a bit. Well wha…

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…

Could it be a Kibimember? What's that? 1^10... Oops, Error that comes back as one. It's not as bad as dividing by Zero 1 /0 Oh noes! *Zap!*

G5's are awesome UNIX workstations. Enjoy.

History? eBay! I had thought power myself. It clearly starts up ok -mostly- so from that I figured that a joint expanding and then failing as it got hotter. As said the ram had be…

Uh, no. Assuming that we use the binary equivalents of the metric prefixes, a gigamember would be the 2^30th member. That would be member 1,073,741,824. What you are thinking of…

slot-loader / electronics {+} IIci's / cases are nice and clean Click to expand... + cryogenius's ATX power supply and VGA out hacks = two working Macs with modern* guts in vi…

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 ...

Always nice to have some reference books when you get into the vintage Macs. Lots of information when these machines were the best there was. Good find!!

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…

Is this yours? I'm amazed it's not had the 640 x 480 mod done, or has a bigger HD - everything else is there (Appledesign speakers, split keyboard, PDS PPC card!). JB

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 …

it's ram simm has 16 464M4B1 chips. Anyone wanna look at some RAM SIMMS and see if you see any 416M4B1 chips, then tell me how big said ram simm is?

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…
