Hi,
I am currently modifying my Teletype ASR33 into a LT33
according to the
DEC specifications to work with my PDP-8/L. Does someone know what is a
Thyractor (GE 6RS20SP4B4) ? Some kind of voltage clamping device ?.
How could I make one, using, for instance a pair of thyristors or a pair
of zenner diodes ?
Hey, look at the function of the little relay card in the ASR - and
build something similar. I have two of this modifies ASRs, it's really
nothing special....
Regards,
Philipp.
