Does anyone have documentation for the MITS 88-2 SIO rev 0
serial IO card ? I got one of these dinasaurs (REAL cheap)
with absolutly no information. It has a 6850 style UART
chip and a plethora of pads marked with things like Mx, Nx,
Jx, Kx, Ix, Yx, Lx, and Zx (where there are several pads, with
x ranging from 1-4, 1-8, 1-12, or 1-16, depending on the letter).
I will gladly pay copying and postage charges to anyone who
can mail me directions on how to get this working...
Thanks
Bill W
