Classic busses (was Re: Whats a reasonable collection?)

I have seen a "sit-on-the-top" Zorro expander for the Amiga 1000, but almost anything people are likely to see are ZorroII cards. They require a ROM or a PAL simulating a ROM to provide a few nybbles of info about the card - the vendor and type code, what kind of I/O or memory space it needs, etc. That's the Commodore "AUTOCONFIG" spec which predates Plug-n-Play by quite a bit. Turbochannel is the bus I've seen most often with DEC RISC workstations, although I think they were not the only vendor to use it. The MIPS boxes and the early Alpha boxes were Turbochannel. Mostly, it was used for frame buffers, but I think there were one or two non-graphic Turbochannel cards. -ethan ===== Visit "The Seventh Continent" http://penguincentral.com/penguincentral.html __________________________________________________ Do You Yahoo!?
