Jameco is one of the many places I shopped for parts. I even have a
screwdriver I use often. Opps, it has JDR Microdevices on it.
I ordered a $3 cable from them recently which with shipping, small price
minimum added up to ~ $12. Their website allowed me to determine that
the cable was the exact one I needed. Unforgettably I did not order
connectors as that may be the real problem.
Jameco even survived some "Gray Market" sales unlike another Surplus
Electronics store which closed. A TV station showed a picture of
Jameco's building in the piece on the "Gray Market". Jameco appears to
be buying up the stock of the closing other Surplus Electronics stores.
I think you are referring to Tony's many articles as CoCoROS does not
show up in "Rainbow text searchable index v1".
