This list was compiled in April 2001. Obviously, most of the parts can be obtained from alternative sources. Part numbers are from Jameco Electronics, and total cost is about US$ 75, if you get ONE PC board from me.
The PIC chip is not identified on this list, because it is optional, and "application specific". There is also no DB9 connector identified, but one is required and must be "hand - wired" to the board, for the RS232 port. ( there wasn't room for a PCB-mount version )
If you REALLY want to minimize costs, the EPROM programmer is not ( really ) necessary, so all the parts associated with the EPROM programmer ( and the EPROM itself ) can also be deleted from the list.
Some of the "smaller" items ( capacitors, resistors, IC sockets, etc. ) are only available in packs of 10 or more, so double-check the part descriptions when ordering these parts, or you will ( accidentally ) end up with a LOT of "extra" stuff. When I ( eventually ) figure out my costs, I will also offer a complete "kit" of parts, probably for about US$ 80.
The US$ 75 cost does NOT include the programming language book, and you will need an EPROM eraser, if / when you start using the onboard EPROM programmer to ( permanently ) "save" your programs. I use a small eraser called DATARASE II, ( Walling Co. ) which sells for about US$ 50, and holds 4 chips. ( available from Digi - Key )
