I received my first batch of boards for this unit using the PIC12F629 chip.
All is working. I have tested it with a old Compaq PS/2 and a new 'El Cheapo' $7 PS/2 from Microcenter. both work...
I have one extra that I have built from the test run. It has mounting holes for a standard 1591XXL case
PM me if someone want's it. $25.00 + shipping
