Sure. But who will fab the big, odd-shaped UniBus boards? Do you
have
enough UniBus transceiver chips in stock?
If you have (?) the scematics of the RK611, how much
work would it be
to put this into a fpga-design and add connect this to a (better four)
CF-card socket(s) Then a cheap 32mb CF card would become a RK07+
media...
Hmmm. Replicating the RK611 in an FPGA is an interresting idea. - If
you
can get complete shematics and there are no funky things like an AMD bit
slice CPU in it.
If you follow the RK611-design, there is no bothering
about driver
issues,
There isn't one if I use the original RK611 controler. That is an
other
issue: If you emulate the entire controler, you have to make the
emulation good enough for all operating systems. It may work for a
RK611, but what about a UDA50 with its AMD bit slice CPU or a controler
that has a T11 with some non-trivial firmware on it. You can't stick
this in a (cheap, small) FPGA.
A project like this would be a perfect entry for the
VCFE of next
year, isn't it? (Hurry up, only 50 weeks left! :-)) )
Yes, that is where the
idea for this project was born. :-)
