For the file 'ExpressPCB.zip':

These are schematic and board layouts for the software produced 
by the guys at http://ExpressPCB.com

Version 2 is tested. Version 3 is not yet developed.

ti keyboard rev 2.pcb is the PCB layout file
PS2Keyboard rev 2.sch is the schematic

This layout has room for a connector for the PS/2 port, two
power connectors (to permit pass-through TI-99 power), two
keyboard connectors (to permit connecting the original
keyboard at the same time, though I'm not sure whether that
will actually work!), and has pads to connect wires for the
Alt+F9 through Alt+F12 output functionality.

If you do order a set of boards, let me know, I might buy one
off you so I can test the layout. ;)
