Before that I use tape recorders.
Using a classic machine, how novel. My iPhone
and androids already
compute everything I need. Before that I used other machines still more
capable than classic systems.
AVR can measure small signals using the A/D and then
do a bit of
looking for zeo crossing to
detect bit times.
Even that is too much work, since the AVR has an internal
comparator
(that will fire an interrupt on crossing), no need to measure voltage
levels. But, as I noted in the original email, I already tried that,
and did not have success.
