Thanks for the comments... I asked mostly because the ADM-3A has both
RS-232
and current loop interfaces built-in (on the same female DB-25), selected
by
one of the
DIP switches.
I just hate having to make a custom cable for every terminal and computer I
own or work <snip
I have some specific pinouts for current loop on my site... for dec pdp
11/05, swtpc 6800, altair 680, and rs232 to current loop conversion.
