Thanks for the comments tmtomh. They showed up while I was typing the above entry.

AWS95 (Q950 with extra PDS card) / I couldn't get it to boot from the fast SCSI PDS card.

LEM implies that it'll only boot "Apple's version of Unix" with the card installed

So you'd have to go get a full '040 CPU

The Overdrive has a full '040 onboard

a Q650 or 800 will easily allow you to install more than 68MB RAM

Good point

without having to spend any money on a CPU upgrade.

Already spent

I can say that I had a Performa 640CD/DOS once, and it was the most fun I've had using Windows on a 68k or PPC Mac - very cool!

Inspiring, thanks. Just a thought, but is there anything to prevent me using the 640 DOS card in another (33MHz '040) machine?

The IDE-based Macs like the 630 are an absolute nightmare for *nix IMHO. / And the 650/800 have the extra bonus of being supported by A/UX.

Well then, I think we have a weiner [

Pity it won't fit in an SE/30 shell, but that's why I ordered a spare Overdrive }

Another point: seems from a quick search of the NetBSD forums that you need to disable cache on the Overdrives to boot. The second one I ordered was cacheless for this reason (and price). It's also the version for a 605 (25MHz -> 50MHz).

I also ordered some of his variable speed overclocking kits. Let's see ... peltiers or liquid cooling....?
