Random find in my local book store's pile of scrap electronics heading for
recycling - a Netronics Phoneme speech synthesizer. IC dates all around
mid-1982.
I just have the board, no case or anything, but it appears to be reasonably
self-contained: there's a connector for PSU, a phono which I'm guessing is
speaker out, pots for volume and pitch, and a DB-25 connector. The DB-25
only has pins 1,2,3,7 & 20 in the socket, so I'm assuming it's RS-232.
Does anyone know anything about these? Assuming it still works (it looks
like it just expects 6-9VAC or thereabouts on the PSU connector), is the
control protocol documented anywhere? DIP switch settings? (there are 8 on
the board, labelled BSY, 3, 2, /C, /C, B, P, C)
Looking at the PCB traces, it appears to allow data input by either pin 2
or 3 (dictated by the '2' and '3' DIP switch settings), but there's no data
sent out down the serial line, so communication is write-only.
I suppose it's possible that I hook up a terminal and (assuming that I have
the line parameters right) start typing English, but it's probably not that
simple ;)
cheers
