[A83] Re: calculator networking - good idea?
Uhm... assuming that all 83s run at a similar speed, if the sending calc
slows down the sending to an acceptable range... everything should work out
fine, the thing is that with manchester II encoding, accuracy in timing can
be quite low and still work fine, as long as the reading side waits more
than 1/2 the delay between each significant change...
oh well... obviously this was just a suggestion.. and in my eyes seemed good
(but maybe it's not... or just not optimal :) )...
