Absolutely correct, Martin.  Here is the definite answer:

 Donald E. Knuth, "Digital Typography", footnote on page 27.

 | \TeX\ has no connection with a similar-named system recently

Thus, Peter, there is no "TeX for CP/M".  This one is called "TEX".

I never expected that a slightly different spelling leads to so much
