[GreenKeys] Junkbox cleanup

[Bob McConnell]

While cleaning out some junk out in the shed, I found a dozen old 
communication interfaces from a discontinued line of credit card 
terminals. These cards are 5.5" x 7", have a bunch of passive 
components, one set of RS-232 interface chips, two phone line 
transformers, two MOVs, a 2.45760 MHz crystal, one AM85C30-8PC SCC chip 
and one AM7911PC modem chip.

If anyone is interested in one or more of these cards, I'll need just 
enough to cover the cost of packing and mailing them.
