AMI S2000 series handhelds or other simple devices.
|
||||
Parker Brothers Wildfire, by Bob and Holly Doyle (prototype), and Garry Kitchen
|
||||
|
||||
This is an electronic handheld pinball game. It has dozens of small leds to
|
||||
create the illusion of a moving ball, and even the flippers are leds. A drawing
|
||||
of a pinball table is added as overlay.
|
||||
|
||||
Hardware notes:
|
||||
- AMI S2150, labeled C10641
|
||||
- RC circuit for speaker volume decay (see patent US4334679 FIG.5,
|
||||
the 2 resistors at A12 are 10K and the cap is 4.7uF)
|
||||
|
||||
led translation table: led Lzz from patent US4334679 FIG.4* = MAME y.x:
|
||||
*note: 2 mistakes in it: L19 between L12 and L14 should be L13, and L84 should of course be L48

|

|
||||
TODO:
|
||||
- were any other handhelds with this MCU released?
|
||||
- wildfire sound can be improved, volume decay should be more steep at the start,
|
||||
and the pitch sounds wrong too (latter is an MCU emulation problem)
