Siemens Q500 QUME with 4P4C connector
Mikhail:
Hi there! I became the happy owner of this keyboard!
Its vintage Cherry blacks
Double shot ABS
New old stock, good condition, only dust.
Got as gift!
But, it have a 4P4C connector, and people says that it's "Keyboard from the terminal for programming automatic telephone exchange by Siemens" and it's can't work with PC.
I've tried to connected into PS/2 like https://geekhack.org/index.php?topic=51079.0
and any other pin-out. Don't work.
As I understand, I need to make an active converter. I found a specialist who could develop one, and he requested ~ $ 170.
I find it economically unprofitable.
Can I find ready-made solutions - buy existing ones, find schemes for self-assembly? Any suggestions?
Thanks!

I did not see your post earlier (only just followed a link in an other post) but from what i've read online it seems to by a wyse keyboard, so using soarer's wyse converter (https://geekhack.org/index.php?topic=52597.0) or maybe rewiring it with a tmk or qmk controller

Today i tried Soarer_WYSEverter_v1.30 with Teensy 2.0. Not work. Hid listen:
Listening:
remaining: FFFC
WYSE...
error: WYSE clock low - not connected?
Keyboard ID: 0000
Code Set: 2 (extended)
Mode: AT/PS2
Also I tried replace clock and +5V like http://www.kbdbabel.org/conn/kbd_connector_qvt2xx_qx15.png
Also not work((

then maybe the best option would be to either retro-engineer the protocol (harder without specs or a computer to talk to) or to retrofit it with a QMK pro micro/teensy and retrace the matrix, it also mean removing that vintage intel microcontroller though.
or you can also sell it but it will likely be destroyed for its switches by the next owner, because peoples still harvest vintage black switches for some reasons.

(I was able to ring + 5v and ground to the controller, ground - pin 4, + 5v - pin3. Not like Wise. I tried the remaining two options for connecting date and clock, both did not work with the firmware for Wyse and for IBM.)
Switches i already harvested and changed with MX Blue))
But anyway this keyboard have good sound even with MX Blue!
I want make it work with PC and return to who give me.
I can draw a schematic how's matrix traces goes to the controller. I would be cool if someone tells me after how connect teensy 2.0 (or something) to old controller place and make .hex file!
