Hi please reply as to yes/no availability. Thanks Doug. C-64 Speech synthesizer cartridge - $5 each "Voice Messenger", by Currah Technologies. I have 2 of these, still shrinkwapped. Uses a hardware synthesizer chip (SSI263??), and has an extension ROM that adds speech functions to the built-in BASIC. The first buyer gets a free light pen that plugs into the joystick port, but has no docs or software unless I get a surprise while sorting through my old files. My recollection is that there's a photodiode in it that generates an interrupt when the CRT beam sweeps past it.
