Also known as:

• PCChips/Hsin Tech (unknown)
• Unknown PCB9060D (UNIC PCB marking sometimes)

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.

• Underperforming chipset/board

The motherboard or chipset may deliver subpar performance compared to similar products, which can result in reduced memory bandwidth, poor memory latency, and bad AGP performance. This can negatively impact overall system performance.

Notes:

• Has internal clock generator in the chipset running at fixed 12.5MHz and the connector for external clock is not connected to anything, jumper does nothing.
• There is hardware design problem with the parity chip - seems it is hard disabled in BIOS. From probing I found /RAS and /CAS signals are connected to the chipset but there is no signal coming through.
• Works with TD60 BIOS.
