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).
Supported 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 popular General Instrument SP0256 speech chip, probably the standard -AL2 version (the ending L2 may be still visible? not sure there - on the photo it vanishes under the pot axis). The clock frequency of the oscillator isn't visible (from the perspective from where the photos were taken). The GNDed pins somewhat confirm that it is a SP0256 (Pin1=Supply GND, Pin10,11=A8,A9, ie. only 6bit allophone numbers used).
Other Pictures
- Probably NOT another version of the MHT Speech Synthesizer?
Not sure where these photos come from, why they are here, 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...? Despite of their filenames, these pictures probably do NOT show a speech synthesizer. Though with the 3.5mm socket, it may be some kind of audio output or audio input device...?
