IBM 3178 C2 1984 Restoration - Questions

My IBM 3178 C2 "Blue switch" arrived today.

I'd like to keep this board as original as possible and don't want to replace the controller with a CY8C-059 controller, at least not as of yet.

I've seen references to a converter which appears to be a promicro based controller.

The maintenance guide for the keyboard has this pinout on the controller, any ideas on how this may be hooked onto a pro micro ?

There is a dude(or gal I dont know) from China selling a plug n play controller for these keyboards. However I am not familiar with that controller and its capabilities.

That being said I think the seller actually have a DT account
