 From what I've been told, it came from a "Samurai" 8086 based machine, 
possibly an "S16". Google provided no useful hits, and I couldn't see 
anything on Bitsavers.

The drive pinout appears to be pretty non-standard. It doesn't match up 
with the standard edge connector at all... Shorting pins 49 and 50, for 
instance, makes the "drive active/heads loaded" LED light... The 
connector is a 3M 3433, which is an IDC-like connector with two 
polarising pins, neither of which is in the centre of the connector. To 
make an IDC crimp plug fit, you have to shave off the polarising pin...

Somehow I get the feeling this is going to end with me reverse 
engineering the pinout with a multimeter, and hoping this board uses the 
same programmed 8048 that the other board variant uses...
