|

Milton Bradley MicroVision, handheld game console
|
||||
|
||||
To Do:
|
||||
* Add support for the paddle control
|
||||
* Finish support for i8021 based cartridges
|
||||
Hardware notes:
|
||||
- SCUS0488(Hughes HLCD0488) LCD, 16*16 screen
|
||||
- piezo, 12 buttons under membrane + analog dial
|
||||
- no CPU on console, it is on the cartridge
|
||||
|
||||
12 games were released, all of them have a TMS1100 MCU, with the exception
|
||||
of Connect Four which has a TMS1100 version and I8021 version.
|
||||
|
||||
Since the microcontrollers were on the cartridges it was possible to have
|
||||
different clocks on different games.
|
||||
The Connect Four I8021 game is clocked at around 2MHz. The TMS1100 versions
|
||||
of the games were clocked at around 500KHz, 550KHz, or 300KHz.
|
||||
|
||||
Each game came with a screen- and keypad overlay, MAME artwork is recommended.
|
||||
|
||||
TODO:
|
||||
- Add support for the paddle control
|
||||
- Finish support for i8021 based cartridges
