Something must be wrong here, the 29B/unipak is very easy to use. I was the rep in Houston (USDATA) and I must have sold 50 of these. It went for $4500 with the unipak.
A typical demo we would plug in a dumb terminal, its a lot more effective demo to select a device than from the keypad. One of these I sold to Gateway Technologies, Rod Canion. The demo and sale went down at a pancake house on the Southwest Freeway. They used it to suck the BIOS out of the IBM PC, and form Compaq Computer.
