[Coco] Source for CoCo cassette cable, or components to build one?

[Al Hartman]

IBM's thinking at the time was that it would be easier for people to go into 
a Radio Shack store to buy a cassette recorder, and cable than it was for 
IBM to manufacture and stock such low ticket items.

They even sub-contracted out the original IBM Graphics printer to Epson 
(MX-80).

I saw original PCs (with cassette port) at the college I went to (around 87) 
which was the first time I ever got to verify they started out with cassette 
ports :)  Where did this standard originate? Did something have it before 
the TRS-80 Model I? I never realized that the PC copied the TRS-80s :)
