Hi, this probably is beating a dead horse, but I finally
acquired a datasheet for the 6RS20SP4B4, used in the LT33
teletype modifications. I have scanned it and made it
available at
http://so-much-stuff.com/pdp8/pdf/6rs20sp.pdf
(The data sheet actually describes the 6RS20SP and 6RS5SP
families.)
Contrary to DEC documentation, it is a thyrector (not a
thyractor, which would have an inductor in it).
