Also known as:

  • VISIONEX GREEN-B

Known issues:

  • Leaky Ni-Cd clock battery

The Ni-Cd battery may be leaking, risking damage to PCB layers & nearby components. Promptly remove the battery & clean corrosion/alkaline salts from the board. Use white vinegar to dissolve salts, but exercise caution as vinegar can corrode exposed metals. A thorough examination & repair may be needed. Replace battery with guide: https://github.com/wiretap-retro/Not-A-Varta

Notes:

Cannot cache the ROM BIOS from $D000-EFFF. Only caches ROM BIOS from $C800-$CFFF. (It can cache the VGA BIOS and system BIOS.) This must be a chipset problem as I tried several BIOSs for this Chipset, and they either hide caching entirely or only allow you to cache $C800-CFFF.
