Mr T, it's quite likely the motherboard in your Mac is the original, though upgraded to 512K. The original boards were shipped in 128Ks even after the Fat Mac 512K was introduced. …

So to be truly stock your ROMs should be 342-0220/1-A ©1983 variety, NOT 342-0220/1-B ©1984. Click to expand... Henry, since Beck-Tech read out the Apple ROMs to develop its me…

Don't you hold down some modifier key as you open the Memory control panel and it gives you that option? I remember something like that. Because really, RAM doesn't fail all that…

I like to know if one can determine by the label on the back of the macintosh case or better by the serial number what revision of the logic board has to be in it. The best would…

Carlo, since my HyperDrive 20 Mac is a Macintosh 512k with the "512k" label on back and with a stock Macintosh 512k board that has never been swapped out or upgraded, I am happy to…

I first wanted to hear from PB100 owners … Click to expand... Err what I posted about was expressly about a PB100, unless I'm wrong! JB Click to expand... Sure! I just …

Carlo (Mr.T), after reading your post again I see that you are expressing disappointment over not having a stock 128k. What I can say is that 128k logic boards are often sold on E…

Now I can't put the front bezel back on! This really bugs me! The stupid plastic tab has nowhere to go but to cut into the hdd power cable, it's gonna cut the power cable if I pr…

Glad you got it sorted. Sounds pretty kickass.

I have been looking for one of these for a very long time, on and off, and just did another search on a whim. Within the past 10 mins., I landed one on eBay for $5 plus shipping (o…

For the records: A 9.2.2 CD bundled with a later G4 worked quite well. It´s still verry strange to me, but the bought 9.1 refuses to boot, but a 9.2.2 works (even if it was made f…

It turned out be a flaky floppy drive. I got it fixed and now I am running DOS 6.22, Windows for Workgroup 3.11 and Windows 95 all on the Peforma, side by side with System 7.6.1 …

just to clarify anything that might be unclear, the iMac was $20, not $200 (i did not forget a 0) and (so far, so good! no more trouble w/visa } ) Click to expand... …

i installed it w/o any languages, Asian fonts, printer drivers, etc. and it still has a 1gb+ left

Have you seen this? A T-amp kit for $20: http://www.parts-express.com/pe/showdetl.cfm?Partnumber=300-385

Very nice. I am a little surprised that 10.3.9 fit with some extra space on a 3GB HD. I find anything with OS X needs at a minimum a 10GB to be fully functional.

I couldn't make heads or tails of the pinout on the schematic linked in the previous reply. I found schematics for the 1.8 amp power supply in the LisaList groups in Google Groups…

the ibook WAS 300mhz, 96mb of ram, 3gb hardrive, os9.0 now it IS 300mhz, 288mb of ram, 3gb harddrive, Airport, os 10.3.9, and my mom's first mac (so far, so good! no more trouble …

How wrong can you go with deals like that. The iMac is worth that even dead. What kind of specs does the iBook have?

Have a look here and here.

i dont remember, does dos 6 support 32 bit partitions? if not you may be limited to 2 gig's each (or using win-dos or pc dos 7)

I had the pleasure to pick up a Performa 640CD with DOS card for FREE! yesterday. This thing had its RAM upgraded to the max: 52 MB on the logic board and 32 MB on the DOS card. …

Thanks for the answer! First though I'd reseat the RAM and rebuild everything. Then I'd do the old "clean the board with metho" or put in in a dishwasher, leave to dry for …

i am going to take it to the apple store next friday,just in case they actually know what they are talking about. if they quote me way to high of a price to fix it, or tell me that…
