I have a custom //e case that uses a strange keyboard adapter. The adapter plugs into the keyboard rom socket and uses one pin of the keyboard controller. The keyboard rom and controller are not on the board anymore.

eBay. The computer was presumedly part of a whole rig of at least 10 measuring computers that had two Mountain Computer "A/D+D/A" cards as well as a Mountain Computer "The Clock". The guy who sold the computer said that the systems were used in a laboratory for some automated measuring tasks and were connected to each other by a network. The network was most likely realized by using the game port and consisted of one master connected to 3 slave systems.

I don't have any more information and I don't know what kind of keyboard interface was used. Maybe several Computers were connected to a single Keyboard?

Tis computer had 'wings' installed on the side to be installed in a 19" cage.
