Here you will find four different Gerber files for four different boards.
The difference here is that for each board there is a SMD component based
board and a through-hole based board.

Revision one boards are meant for
CPU Tests Vol.1 v1.1.1, CPU Tests Vol.2 v1.0, and SCSI HD Tests v1.0.

Revision two boards are meant for
CPU Tests vol.3 v1.0, and CPU Tests vol.4 v1.0

TH = Through Hole
SMD = Surface Mounted
