[Milsurplus] LM/BC-221 calibration books files

[Kenneth G. Gordon]

I have published the information on recreating cal books on my website here:

http://www.w7ekb.com/glowbugs/Military/bc221lmfiles.htm

and the Royal Signals site also has my page on their site, here:

https://www.royalsignals.org.uk/articles/BC221-cal-prog/index.htm

This site has some helpful information on DOS emulators

And I have used DOSbox. It works quite well.
