  TODO:

  Quasar
  ------
  - Sound (missing invader effect - still not sure all noise in correct places)
  - Phase 3 - seems awfully hard - dip settings ?


  - Make Asto Wars to boot
  - Make Cat'n Mouse to boot
    (it jumps to unpopulated rom, check jump at 0x2e62 and 0x4076)
  - ...

Quasar by Zaccaria (1980)

1K files were 2708
2K files were 2716
512 file was an 82S130 (colour and priority PROM)

2650A CPU

I8085 Sound Board

Zaccaria "Cat 'N Mouse" 1982

similar to "Quasar" execept it uses an 82s100 for color table lookup
and has a larger program prom
