MHT Speech Synthesizer aka Sintetizador de voz (MHT Ingenieros)
Technical
Probably uses a SP0256(-AL2?) chip.
- The I/O addresses are unknown.
- The clock frequency is unknown (as shown on the photo, it uses an oscillator, ie. NOT the 4MHz signal on the expansion port).
Support software
- No (known) software?
Pictures
- MHT Speech
The part numbers on the chips seem to be scratched-off (or covered by paint). The "GI" logo on the large chip implies that is the polular SP0256(-AL2) speech chip from General Instruments. The clock frequency of the oscillator isn't visible (from the perspective how the photo was taken).

Not sure where these photos come from, and if they do actually show a speech synthesizer. There isn't much visible, the upper board contains an enormous amount of logic chips (no idea what for). The lower board contains even more logic chips (strange), and two big chips, which might be ROM, or RAM, or maybe a speech chip...?
