While dropping by a local thrift (where classic game cartridges were last seen 1 and half years ago) I spotted at least 3 square modules which I recognized to be Unisys or Convergent Technologies machines which ran BTOS/CTOS. As I recall these modules snapped together along a bus (X-bus?) that ran along the bottom of each module. I didn't take a closer look to see what they were, but if anyone in the list is interested, I could go back for them to determine what is there and what price is wanted (yes, I'm offering to pick up and ship for a nominal fee - I'm just a nice guy..)
