Adapter (+converter?) needed

Does anyone know of what adapter (and what converter software, if necessary) I could use to get this keyboard to work? A quick search for 8-pin to PS2 is not yielding much. Interesting keyboard with a sort of Fujitsu Peerless switch I haven't seen before: different appearance from those on the wiki and very different feel from my Epson Q203 (keycaps incompatible too).

Data General? Just the top hit when I search for the part number. Sounds nice!
As for connectors:

Woops, that was easy! Thanks. I think these are actually Fujitsu Leaf Spring 3rd gen. The feel and sound is very nice.

Is this the keyboard for a D411/D461? The key and LED layout seems to match the drawing. If so, the pinout for that 270° DIN-8 would be as listed there. And, based on the signal names given, I am guessing the protocol will be the same as the 6246-A for the D210/D211.

I reckon you might have commented looking for help on my YouTube channel today? Feel free to PM me here if you need any help with conversion.

This ones seems to be the younger brother of the DG 6348-A, which looks very similar and actually is FLS 3rd gen and overall slightly better built. I have seen one which has been converted via hard mod ( ... -keyboard/). Not easy to find documentation on the machines those came with, but afaik (I tried to find some information when I got my board) it was compatible with the D-412 and the D-412+ terminal. Maybe this one was just a cost-cutting replacement model and uses the same protocol?

Couldn't find any specific documents about those two terminals, unfortunately. Maybe someone can help out? I'm also interested in this, since I kinda hesitate to tinker around with the PCB just to make it work.

Edit: On second look, I think it is just a 6348-A. In that case, you're right and the switches are FLS. Board is definitely worth it, built like a tank while still very slim. Nope, I'm stupid.

Also, great job to me not recognizing shallot runs kuritakey. I should go to bed...

Haata has a 118-5237 with Peerless and the PCB says N860-4735. I'm not certain whether it would need to change based on switch type.

I have a 6246-A here (someplace) and have been meaning to have a go at figuring it out.

Based on the user manuals showing both kinds of connectors, I am inclined to believe that all of these use the same protocol, though you never know. Furthermore, the patent describes a capsense mechanism in addition to the identification part. Perhaps an even earlier Key Tronic?

I've got the 6246-A converter mostly working. See here. I will now keep an eye out for one with a DIN connector to confirm that it's the same.
