almost actually. there was a lot of interest in the ham community
with tcp/ip and a lot of hams were working for dec, data general and
ibm at the time. plus we were very close to mit and bolt, beranek and
newman where there were a lot of hams and the flow of information was
incredible - it was hard to keep advances in digital communications a
big secret in those days. as soon as somebody had a new product or
new approach to a problem, everybody else knew it within 24 to 36
hours - thus, the forced product cycle was amazing.


Certainly the concept of digital communications has been around for much
longer than computers or the Internet. Morse code is a form of digital
communications. I used to work on teletype machines using tape readers to
send messages at 100 wpm using FSK (frequency shift keying) modes on the
transmitters. All digital. In fact, teletype was 8 bit. A start bit, six
information bits and a stop bit for each "word". Basically 50's technology.
