EISA is a pretty good bus, something like 6 times the bandwidth of ISA.

Isn't it completely upward compatible from ISA (i.e. we can use it just
like a ISA bus).

I certainly wouldn't object to an EISA bus on the riscy board, and if
the ARC chips support it it's practically free.

I believe the ARC 100 manufacturing kits include plans for 3 EISA boards
Etherenet/serial, audio/mouse, and video.  Whether we we use any of those
would just be a price/performance decision.
