enigma2 (1981)
2xZ80 + AY8910
Original dedicated board
enigma2a (1984?)
Conversion applied to a Taito Space Invaders Part II board set with 1984 copyright. hack / Bootleg ?
enigma2b (1981)
Conversion like enigma2a, but boots with 1981 copyright and Phantoms II title
TODO:
- enigma2 - Star blinking frequency
- enigma2 - Sound is incorrectly emulated (see MT07777)
- enigma2a + enigma2b - bad sound ROM?
