[GreenKeys] Black tape

[Don Robert House K9TTY]

There were also many approaches for the numerical control industry… you know, controlling machines to make things.
The black tape I am familiar with was Mylar with paper on both sides.  The blue tape was normally all Mylar with no paper, that being written… Teletype did make some test tapes that were blue paper with Mylar in the middle.

Various punches and readers were used, but the model 43 was popular for these applications.  Western Numerical Control used to refurbish the reader punch units. For some time they used to show up on eBay.
