I've converted many things with keyboards attached into USB keyboards over the years, and I get various requests for things to be converted. Often I can go back through the archive and send them a link to a post on this blog where I have done exactly that. Sometimes I get new ones. One that came in, quite a while ago actually, was to convert a USB conversion kit for an Oric-1.
Oric-1 Repair Part 1). For the moment, I've put the mainboard to one side and borrowed it's keyboard to build and test the Oric-1 USB keyboard conversion. The keyboard connection is quite neat, there is a 14 pin header on the back of the main board which plugs directly into a 14 pin socket on the back of the keyboard.
