Datacast Controller by Defence Products
The PCB is named Datacast Controller, and the outer casing is customised
for 'The Stock Exchange'. Maybe other ROM variants exist for this
controller.
Hardware:
---------
CPU: 80186
RAM: HM62256 x 8
PCF8582
Video: SAA5240 + 2K RAM - Teletext Decoder
SAA5250 + 2K RAM - Teletext Acquisition and Control
SAA5231 - Teletext Video Processor
Serial: D8251 x 2 - USART
AY-5-8116 - Baud Rate Generator
MC145406 - Driver/Receiver
Ports: Printer
Modem
Monitor
Keypad
I2C Slave Devices:
------------------
22 SAA5240
A2 PCF8582
C0 ?
TODO:
- implement keypad
- complete SAA5240 emulation
- feed SAA5240 with teletext packets
