If you simply want to BUY this board, you can get three high quality boards ( with through - plated holes ) from ExpressPCB for about US$70, using the CAD file in this section of the website.
You can also buy ONE board from me, for US$30, shipped by ordinary postal service. I get them from the same source, so the quality is the same. Total cost to assemble one yourself is about US$70, or you can get an assembled / tested SBC from me for US$100, with an 8K EPROM, and sockets for the EPROM and PIC chip.

Here is the pictorial for the SBC board, so you can
figure out where the parts go.
