Tiger Electronics K28: Talking Learning Computer (model 7-230)
* 8021 MCU with 1KB internal ROM
* MM5445 VFD driver, 9-digit alphanumeric display same as snmath
Tiger Electronics K28: Talking Learning Computer (model 7-230/7-231)
* PCB marked PB-123 WIZARD, TIGER
* Intel P8021 MCU with 1KB internal ROM
* MM5445N VFD driver, 9-digit alphanumeric display same as snmath
* 2*TMS6100 (32KB VSM)
* SC-01 speech chip
* SC-01-A speech chip
Model 7-232 was released a few years later, it is on entirely different hardware
and emulated in tispeak.cpp.
3 models exist:
- 7-230: darkblue case, toy-ish looks
- 7-231: gray case, hardware is the same
- 7-232: this one is completely different hw --> driver tispeak.cpp
TODO:
- is model 7-231 the same hardware or just a redesigned case? (one is gray,
other is blue and looks more like a toy)
- external module support (no dumps yet)
- SC-01 frog speech is why this driver is marked NOT_WORKING
