Jeff Js Mystery Items
Mystery Keyboard #1
This keyboard has a row of illuminated switches!
A homebrew? Some computer console?
I adore the switch with the "lift to press" cover.
Next time I'll bring some Windex and clean the keys.
The illuminated switch panel was only glued on
The top comes off too
The keyboard PCB looks like it can be re-wired for other keyboard scanning and encoding?

The residue on the keys looks like there were once label-stickers on them.
Mystery Keyboard #2: Honeywell
Honeywell keyboard console
I bought this from some mail order surplus catalogue
in the late 70s or early 80s.
The keyboard is all hall effect sensors (never a contact bounce!).
The lid hinges open to show the power supply and boards:
- the driver board and incadescent lamps
that illuminate messages on the console in those squares
under "format" "program level" and such
- a single character 5x7 LED and several 7 segment LEDS on the upper panel
I removed the logic board long ago: all wire-wrapped TTL,
mostly shift registers and buffers.
I guess it was some early data-entry system that retained
the
keypunch keyboard layout.
Mostly. Somewhat.
- The numeric keypad is 123 / 456 / 789 like a telephone or keypunch,
not 789 / 456 / 123 like modern computer keypads.
- no "enter" or "return" key but "dup" "rel"
- red control keys for "data ent" "data ver" "data chg":
definitely emulating keypunch and verifier
- orange keys for motion control (move a column, field, record)
But it's NOT totally true to a keypunch:
- there are [ ] \ and up-arrow keys like ASCII keyboards
- no ¬ (PL/I "not" symbol)
- no multipunch/compose key
Mystery Keyboard #3: IBM
I have an IBM keyboard/console similar to the Honeywell.
- keypunch style keyboard in red, white and blue.
The EBCDIC encoded keyboard is all hall effect switches but no click like model-M.
- Purchased by mail order from Herbach & Rademan in the 80s
Photos coming soon.
Mysterious computer panel!
I salvaged this front panel and not much else, so I have no context for its use.
The rectangular bezel is a single line neon alphanumeric display:
a Burroughs self-scan SSD0132-0039.
There was a full height 8" floppy drive in the left.
What was it?
My guess is that it was some communications controller due to the
8 modem-status LEDS over the thumbsheels and the 8 "CIA ENABLE" switches.
The card from the right gives some clues:
- commands to display PSW
- "CPU stops on a PER event in 3650/3670/476 mode. Stops in 3690 mode if test mode set."
