(to me), unmarked system. From what I know of the late owner, the system may be related to the aircraft industry, as many of his tools and bits and bobs were from Boeing surplus. slide-down screen, a complex keyboard. It had two Canon 5.25" floppy drives mounted behind the screen, next to a USi Pi3 amber monitor. <snip> Others may have said something similar, but here is my 2 cents....The USi Pi3 monitor was sold as a package by Protecto along with the liquidated Commdore B-128 computers in the mid 80's. They bought the remaining stock. Assuming the monitor came with the terminal, one could deduce that this smart terminal is also from the mid 80's as well. Bill
