I've been toying with the idea of creating a homebrew computer, similar to Bill Buzbee's (www.homebrewcpu.com).
First, however, I'd like to have a plan for the mechanicals - a backplane and prototyping boards. I'm looking for something like 10 slots, about 100-150 signals.
I think something like DEC's Q-bus is the right form factor, but I'm not sure about the availability of prototyping boards.
I think VME bus is a strong possibility, but I can't seem to find a good resource for prototyping boards. A lot of links I've found don't seem to have easy answers. Plus things look pretty expensive. Ideally, here is a backplane that looks perfect: http://www.twinind.com/catalog_detail.php?id=58 However, $500! Then I'd need a card cage. The Vector Electronics CCK220-6U looks pretty good, but Digikey lists that for $220. So, $720, then I'd need prototyping boards!
I don't like ISA, despite the large number of backplane and prototyping board choices. I think the ISA edge board connectors are too cheap and I don't like the size/physical layout of the board itself.
Does anyone have any suggestions?
