"Aries" MV1FZ

"NO" MV1FZ

  • Vertical board is soldered
  • Normal DIP format 68k CPU
  • Through-hole 5% resistors video DAC
  • Custom chips are marked "A66" (NEO-B1 ?), "NO-03", "NO-5" (and a blank one)
  • Original YM2610
  • Uses a bunch of PALs
  • Backup RAM saved by a supercap


"NO" MV1C

  • Uses the same "NO-03" and "NO-5" chips as above
  • Gold nugget 16MHz 68k CPU !
  • The "9817 870768593" chip is probably the same as "A66"
  • Space for a QFPR clone of the YM2610 in U1A ?
  • Uses a bunch of PALs
  • RAM chips on the back side
  • Backup RAM saved by a supercap

  • YM2610 clone named ECW08-4 ?
  • 4 ROMs as in original MVS boards: BIOS, SFIX ROM, M1 ROM, LO
  • Backup RAM saved by a supercap


"Gobit" MV1C

  • Same custom chips as above
