Errp... a PT08 not a DW08. The DW08 is on a different page and is a
bus converter.
...DEC's pre-TTL TTY interface made from W-series
and R-series logic.
8 x MC724P
"Dual J-K Flip- Flop"
5 x MC724P "Quad Input Gate" (NAND)
I don't believe that the 724 is both a NAND gate and a J-K flip-flop

Almost certainly RTL. The 3.6V power line is the big
clue. I know I
don't have data sheets for them, but I could probably find pinouts if
pushed. I guess you have that info on the schematic, though.
Pinouts I got. Physical and electrical specs (and actual parts!) I don't
got.
Thanks,
