The PCBs arrived! They look great, first news is that the dome switches are not an option bcause they don't fit
Still the tact ones fit nicely so its resolved my dilemma and saved me having to make keyboard parts!
I'm still waiting for some parts to arrive and I need to get some 74 logic chips when I get paid in a few weeks (this months budget spent !) but at least I can get started. Just need to remember what I did with all those IC sockets....
