Giving away PowerMac 1,1 (G3) hardware components

Post by mabam »

Kind of "following up" on this post from February 2017 (https://emaculation.com/forum/viewtopic ... 232#p56058):

That's what I get for thinking :mrgreen:

Xlr8yourmac.com has an old guide on how to convert an ATX PC power supply for use with G4 sawtooth machines, I think it's the same for G3 B&W mini-towers, but it won't fit the case. Beige G3's, I believe used the same pinout as a standard PC ATX power supply.

If you still have the old G3, you can use an ATX extension cable, and mod it, rather than the cable of the PC Power supply, to get an old G3 B&W running again.

None of which helps you if it's an iMac G3.

Edit: Here's the G3 B&W ATX conversation, NOT the same as the Sawtooth:

This is a PowerMac 1,1 from May 1999 – see https://everymac.com/systems/apple/powe ... 00_bl.html. The specs are (partly upgraded at some point):
• 400 MHz PowerPC 750 (G3) processor with 1 MB backside cache
• 4 × 128 MB RAM
• 40 GB Ultra ATA/33 hard drive (next to the original 6 GB one)
• Philips DVD writer
• ATI Rage 128 GL graphics card with 16 MB of SDRAM

I don't have the power supply anymore which is why I didn't respond to above post back in 2017. But now I'm using the case to build a new Hackintosh and need to get rid of everything that is in there.

I can't test anything but I think it was just the power supply that was broken. Anyone interested in (part of) that stuff? Just let me know.

I'm done building the new hardware into the housing. It boots into the BIOS so the hardware should be fine.

Here are some pictures:

I hope to begin installing macOS onto it soon. But there's other stuff with a higher priority that has to be done first.

Since you're doing a major hardware mod anyway, you should slip in a Raspberry Pi or similar that boots right into Mini vMac, and have a KVM inside to switch between the two sets of hardware ;)

Leave it on System 7 by default and with the push of a button bring the screen, mouse and keyboard over to the main hardware :D

Nothing like an entire firewalled OS as a security layer ;)

The programmer's button at the front has no function anymore and is available … ;-)

I have to disappoint you: I won't do it.
But I like the idea.
