I am happy to report that (my) Pin 4 is indeed common to the power supply ground pins. And in fact every piece of metal in the case.
So now I know the polarity... what is the recommended battery I should try? (A non-rechargeable one I presume)
thanks!

ok so here's some progress: I abandoned the dongle and dug out an old TELEX keyboard which has a 5-pin DIN connector. I realized that the keyboard works great - I just need to press ALT-SHIFT to use the keys (there are some dip switches on the back I can fiddle with, perhaps that will address...
sigh... :biggrin:
Yep will do!
Well yeah I am attempting to use that little dongle to connect a PS/2 keyboard... well that's embarrassing I assumed a 5-pin DIN-style AT keyboard was more or less the same as an XT class one
umm actually not sure I did this right...
Sorry I wasnt quite sure what you meant by "negative power supply connector pin" (the AT power supply connector?) but I tried everything I could find on the board and this is the only place my continuity tester would beep is at the top of "CR2"...
Hi! Notes below 😀
Keyboard doesn't flicker or light up at any point - if I press CAPSLOCK or NUMLOCK it will light up for a few seconds only
Motherboard has the following:
SPEAKER (connected)
MON/COL (jumpered for COL)
KEYLOCK (not connected)
RESET (connected)
TURBO LED (not connected)...
Hello! Some notes below... cheers 😄

Well I am a bit hesitant as I am not sure exactly what sort of battery or polarity.... (googling siemens rolm 98d5192 seems to cough up almost zero clues.)
However referring to...
Hey folks - I have been trying to resurrect an old 386 clone, and found a pristine condition Siemens 386 motherboard on the ebays. It's NOS and I can get it to POST but I have no info on the board.
Even though I have a legit keyboard - hitting <DEL> does not invoke setup.
I also tried...
Great news - my keyboard now works using an (active) PS/2->XT converter... I was able to press F1 and then load BASIC!
At least one simple thing is fixed. Next up? Follow the previous posts to address:
20000 201 - memory problem at 20000
1701 some general HDD or Controller problem
601 Floppy...
well... my screen is a regular VGA and seems to bein black an white, but maybe that's just because the POST stuff and the VGA BIOS messages are only in monochrome?
OTOH my VGA monitor is old, and somtimes the color goes a bit wonky (bad cable I think)
And just to be precise I tried setting the...
