Hmm... I haven't seen the unit, just talked to the fellow on the phone. I asked him what kind of computer it was, he put the phone down to go look at it, came back, and said it was a "Honeywell Bull", also giving me the dimensions (4x3x2). The computer was used by a company that assembles line and bucket trucks. I believe they had a good number of remote terminals set up, and used the system to transfer specs and price sheets. Tom Owad
