Tektronix 4002 Terminal found

[Arno Kletzander]

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.

The 4002A maintenance manual should be correct for my unit (it has that designation on the back). 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,
