Zorro is the Amiga bus - there are two card sizes/form
factors, Zorro
ZorroII. 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.
Has the A500/A1000 expansion even been called Zorro?
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.
I know that there have been at least TC VME expansion chassis, an FDDI
adaptor, SCSI and Ethernet.
Somehow, we've all been forgetting Nubus as well. That's plug and play enough
for me. =)
