    Using a TI Silent 700 for it's ASCII keyboard?

    Hi Folks, I'm trying to find a 7 bit ASCII parallel keyboard to interface to my PT 3P+S board, which will allow me to build up a SOLOS Subsystem B on an S-100 system. Does anyone know if the keyboards in these systems are ASCII compatible? The relevant schematic portion of the keyboard module...

    DEC VTxxx terminals, where did they go?

    I sold mine during a move for $71 plus shipping and it was working perfectly. Now I miss that thing and realized what a workhorse of a terminal it was! There used to be a great deal of these around the Northeast where DEC was located. I wonder where all the terminals have gone?

    California Computer Systems Chassis
