Looking for a Real Oldie

[Robert J. Stevens]

Around 1981-1985 a friend loaned me a Piece of Equipment. It has a S-100 
Bus with five slots Horizontal in the Back. I had a regular Keyboard and 
a Hex Keypad. I remember I cold enter in Hex Code and was able to Access 
a FDC to test it.
Can't be sure of the MFG. But Xpandor comes to mind. My Friend says SOL.
Does this ring a bell with anyone
TIA
