Sega AI driver
Not much is known at this stage, except that the system was intended to be
used for educational purposes in schools. Yet the audio chips seem much more
powerful than what an educational computer requires...
CPU : 16bit V20 @ 5MHz
ROM : 128KB OS.with SEGA PROLOG
RAM : 128KB
VRAM : 64KB
Video : V9938 Resolution 256x212
Sound : SN76489
Cassette Drive : 9600bps
TV Output : RGB, Video, RF
Keyboard : new JIS arrangement (Japanese input mapping)
TODO:
- Cassette, playback is controlled by the computer. Games with cassette
spin up the cassette for about 2 seconds
- The tape sometimes seeks back and forth for 5-15 seconds for the right
voice clip, while the game and player (kids) wait
"In these tapes, by the way, the left audio channel is the narration,
and the right channel the data bursts right before each one."
- Keyboard?
- SEGA Prolog? How to enter?
- Sound box:
Note from ccovell:
"With the Sound Box attached, I connected the output line of the Sound
Box's keyboard pins to one or more input pins, and it suddenly played an
FM instrument and printed "piano" on the screen! From this, pressing U/D
on the pad cycled through the various instruments, and the PL/PR buttons
lowered and raised the volume."
