/**********************************************************************************

PINBALL
Technoplay "2-2C 8008 LS" (68000 CPU). Company also known as Tecnoplay. They still
exist, mainly as importer and reseller of amusement machines made by others.
Schematic and PinMAME used as references
Machines by this manufacturer: Devil King, Hi-Ball, Scramble, Space Team, X Force.
Scramble uses Zaccaria-2 system.

Status:
- X-Force displays correctly, you can coin up and start a game, then no response.
  Test mode works.

ToDo:
- Once you press the credit button, nothing responds (game requires 4 balls)
- Sliding display is too fast to read (much better if cpu xtal changed to 4MHz).
  DTACK needs to be hooked up but it is unsupported. Inserting waitstates doesn't
  work either.
- Mechanical sounds
- Unemulated TKY2016-A and TKY2016-B pair of audio processor chips.
  PinMAME thinks it might be a Y8950, but I'm not so sure. It's hooked up for now.
- Schematic shows sound rom banking, but no machine has those roms, so not coded.
- xforce: sound rom is missing
- spcteam: Bad display - can't tell if keys are doing anything.
