PBS program-Enigma

[Clifford Buttschardt]

The program last night on encryption devices was superb.  I had seen an
earlier PBS version that was one hour long instead of two.  That viewing
left out all the reference to four disk devices as well as the use of the
teletype machine, which in my view was even more interesting that the
Enigma machines.

Our local PBS station in Los Angeles will be rerunning the entire two
hours this coming Saturday night at 1800 local time.  Again look for the
listing under NOVA.  Those in the West might have a second chance!  73
