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
