I mustt be incredibly lucky. The first serial
printer I tired to use with
a Model 1 was a Sanders 12/7 and I got that printign withing 3 hours of
owning it.
My first ever serial printer took more like 3 days (maybe half a dozen
days). I have excuses, though: my Exidy Sorcerer had two programmable
baud rates, 300 and 1200, and my Creed 7B did neither; my Sorcerer was RS232 and the Creed was current-loop; and the Sorcerer
spoke ASCII and
IIRC the Creed receiving magnet takes about 20mA to flip it over, but
it=;s quite inductive (4H or so?) If you use what looks like a suitable
voltage, you will find it doen't work, the time constant is simply too
long. Sicne the time constant of a n LR circuit is L/R, you do better by
using a higher voltage (80V is transtional) and a resisotr (around 4k).
Been there, done that....
the Creed spoke Murray. I still got it printing
listings fairly quickly.
Is it strictly Marray code? It's ITA2, certainly, but I thought Murray
code comvined the shifts with spaces, so you had 'letters space' and
'figures space' (and you therefore coudn't print 'RS232C', it would
appera as 'RS 232 C').
