Since we seem to be in a "can you top this" mood... In the 1970's, I was
dialing into the NBS TIP with an OSI C1P (terminal program loaded from
cassette tape) using a "modem" (that almost doesn't deserve the name) built
from a kit ordered from a little ad in the back of Byte. The "modem"
consisted of a 2 inch square board with three chips on it. The speaker
and mic hung off of wires. I attached them to the telephone handset with
rubber bands. The "modem" attached directly to the USART chip in the C1P,
talking serial at TTL levels. As one of the chips on the "modem" would
heat up, the carrier frequency would shift (you could hear it). To keep
from dropping the connection, I kept a little baggie with an ice cube in
it at hand and would apply it to the chip to bring the temp down. Played
the pre-commercial Zork on MIT-DM that way.
