Yes. One of the 512K machines I owned in 2012 did have issues.

Stands for this month. ;-P There's a whole thread on TD about this year's projects. https://tinkerdifferent.com/threads/marchintosh-2025-projects.4174/

The 475 I had was this way. I wound up installing a M0350's case lid on it, so it said "Macintosh LC", then "Performa 475" underneath. That meant that it had the indentation that went all the way to the edges, plus the plastic plug that filled the second floppy drive slot. Thought it looked...

Nice. Theoretically, I bet that if a 9" color screen was installed, it might just display 8-bit color.

The typical bodge wires I see are either 20 gauge or 22 gauge. So, a little thicker than the individual conductor from an ethernet cable.

I would go ahead and try the bodge. If it doesn't work, then it's time for another board, either a reloaded board, a good stock board, or modify the back panel and drop in a Centris/Quadra 650 board.

^Nice. Anyhoo, 7100/80 has been completed, except for that one jumper I need to pull from the CD-ROM drive, and the need for the correct power harness with the pigtail for the cooling fan that goes above the processor. Pic is in the "What Did You Do To Your Apple/Mac Today?" thread.

Probably could burn new PROM chips and install those on the board. Or, find a good set and swap those in, other than using a ROM SIMM.

Might be time to try a ROM SIMM... Had a IIcx many years ago that would do the chime, then sad Mac. Put a IIfx ROM SIMM in and it booted up.

Compared to a stock IIci, it's faster, even when the Turbo 601 is running in emulation mode.

@nathall beat ya to it...

Hmmm, interesting. Yeah, would be neat to try out.

The MPC-LX200 looks to be equipped with a Quantum Fireball SCSI 1.2GB drive. MO drive is a 640MB unit, probably made by Fujitsu. The GX1 is a modified 6100/66, so it'll either be a LPS540S, Maverick 540, or a Fireball 540, formatted as a 500MB drive, as per usual. GX1 Limited looks to have a...

^I dual boot mine. 7.5 for System 7 activities, and 6.0.8 for System 6 activities. Installed the Desktop Manager INIT in the System 6 system folder, so it uses the System 7 style Desktop DB and DF files, instead of adding the older Desktop file.

Picked up the 7100/66. Needed a lot of work, due to a Centris 650 with a bombed Maxell being stored atop it. Saved what was/is good. Got a 7100/80 coming to replace it.

I'd just recommend a 2GB or 4GB card, and partition it, if using on a 68K Mac. Can be had cheap on the used market, since most DSLRs that use CF are now equipped with 32GB or larger media, like this 128GB card -...

@dougg3 I'm guessing the drive came from the commanderscott seller? I did see one that he was selling as parts/repair.

*edit* Yeah, just looked at the back of the disk. This is actually 7.1.2P1. Oops. So, that explains the difference.

Also got this back. My old Turbo 601 accelerator card.

Looks like the only file that's named differently is Apple HD SC Setup. On this disk, it's called Internal HD Format.
