My first computer, a Performa 600, has been dead for about a year with a bad power supply. Looking at it recently and getting a wave of nostalgia, I decided that once I get a replacement one, I want to upgrade the crap out of it, so that it can be a really nice 68k machine to do general apps/games on.
There are two different paths I could take on my quest to upgrade it, and I'm just wondering what work best / cost the least.
1) I could get a PDS accelerator like the Daystar or Sonnet 68040s. This would let me keep the board that is already in there running. However, I read on Low End Mac that the Performa 600 "doesn't support a level 2 cache in the Processor Direct Slot, although it will accept accelerators", but I'm not sure if that means that it won't support PDS cards that are solely L2 cache, or if it means that any L2 cache on an accelerator will be ignored. Additionally I suspect that accelerators are somewhat difficult to come by.
2) My other choice which would probably be more compatible is just to replace the logic board with one from a Quadra 650, which uses the same case. Admittedly that makes it less of a Performa 600, but it's really just replacing the brain-- on the outside it'd still be one. I'd also get the benefit of supporting more RAM.
In either case, I would be also adding a fast video card. However, I've never worked with NuBus cards, having only used built-in video on all the Macs I own, so I don't know what to look for.
I may also add an Ethernet card. No idea what I'd put in the last NuBus slot, though.
Any thoughts?
