Someone leaves it up to cause suffering and misery. We wail as we look at all the stuff somebody should have bought and stockpiled. We didn't know then that all that stuff was going to be unobtanium later in life. Woe, woe to use. Hear our lamentations.

Nah brah, the 475s/605s can go up to 136 (128MB with 8 on-board). I've heard of some going to 256+ with a SIMM-doubler of some sort.

I believe IBM just used the same socket for some of their PowerPC-powered servers.

I don't remember seeing that option, except on a few macs here and there. I've always heard that you couldn't disable it, due to it being embedded in the rom (hench the upgraded ROM being able to disable it).

Some people have taken their 475/605s up to 50+ MHz too. Getting rid of that loooooooooong ram check made me check my board again. Nope, still no ROM slot. I don't know if an accelerated video card would be necessary. With max vram, you can get 8-bit 1180x870 that's pretty quick in my...

I know there's an article somewhere where someone ran one in their beige G3, but it suffered from the lack of L2. I had one that I fitted to my Powerlogix carrier in my Powerbase. I never ran it though. Didn't want to take the chance on the one upgrade that works in my Powerbase.

If you can snag a Powerlogix z-force ZIF card, that'l work on all the processor slot Macs including the often-overlooked Powerbase. I think Daystar's one worked too, but only the first generation/version. That is if you have a bunch of zifs laying about. You could even throw in a 604 zif if...

Case looks alright too. Looks like a scsi card and a non-oem video card, which might or might not be interesting.

Would that work on the 040 machines with the LC-PDS slot? Since they didn’t have an 030 wasn’t it an ‘emulated’ pds slot. Yeah, not a lot of room in them pizza boxes. It would probalby need a fully dedicated card that might be beyond the scope of this.

What about us with LC-PDS slot Macs? Joking but sorta serious.

Oooo, your own control panel with custom graphics (in the style of the time). Maybe a little rocket ship to signify acceleration.

VRAM dimms to a Powermac 7200 perhaps.

Got a picture of said vram?

I have 128MB in mine and the ram check takes a minut or so, not five. I would definitely say an issues with the power supply or such, capacitors probably. My two cents.

I don't know why, but I remember Basilisk as being cludgy and crash-prone. I used the hda images from my ZuluSCSI in my 475 and it runs quick and completely error-free. The Daystar QuadControl control panel doesn't even crash it (it does it on the web-based InfiniteMac emulator).

I don't do it myself but for anyone that does any ROM programming, I seent this today. https://hackaday.com/2024/04/20/relatively-universal-rom-programmer-makes-retro-tech-hacking-accessible/

There ain't no drivers for that card for OS X. 3dfx went out of business and got bought out by Nvidia around when OS X was released. If you're lucky you might get it running as a dumb frambuffer in OS X, but that would be a waste and an insult to such a card.
