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

  • Fake cache

The motherboard may include a non-functional or counterfeit SRAM cache, which can adversely affect performance. Signs of fake cache often include soldered QFP or DIP-chips labeled "WRITE-BACK" with traces that do not connect to the chipset.

  • DIP chips can typically be removed and replaced with functional SRAM chips in sockets to restore cache functionality.
  • QFP fake cache chips are often not replaceable with functional cache as the PCB footprints are not chipset connected.

Notes:

This motherboard is infamous for having no cache. The "DCA" technology was a fraud by Octek (see here http://redhill.net.au/b/b-95.html)
