  • this a rebranded MV1200 by ACT Elektronik
  • in contrast to the MV1200, the Flicker-Fixer is optional on this unit - without it, the expansion works as Scandoubler only (not reducing flicker of interlaced modes)
  • an upgrade is possible by adding RAM to the unit (OKI 518221Z-30 or OKI 518222Z-30) and setting the appropriate jumper
