Tektronix 4002 Terminal found

Here is the card inventory of my terminal: (left card cage front-to-back) TC1 Keyboard Logic TC2 Output Data Selector -- empty slot -- TC4 Scratch Pad Control TC5 Scratch Pad -- empty slot -- TC7 Control Function Decoder TC8 Char Rotor Bypass TC9 Y DA TC10 Y Data Register TC11 IN OUT Data Routing TC12 X Data Register TC13 X DAC TC14 Internal Data Routing TC15 Scan Control TC16 Char Gen Mem -- empty slot -- TC18 Plot Control TC19 I/O Control (right card cage front-to-back) Parallel to Serial Converter Serial to Parallel Converter TTY Port Timing TTY Port Level Conv. (the ejector tabs of the last two boards are yellow and have the words "Do not remove card with power on" on them). The cards all seem to be coded with gaps between their contact fingers so they can't be installed backwards or into the wrong slot. I think I can risk the guess that the missing cards would carry the designations TC3, TC6 and TC17.

Thanks for offering to scan it, it would of course be nice to have it available in digital form. If the missing cards are necessary for the operation of the terminal, I'm afraid I won't be able to do much about it in the foreseeable future. So long, -- Arno Kletzander Stud.
