Hi dear friends,
I have a problem with a oki OM-2 motherboard in a 8088-2 PC by tandon. At startup there is an "System parity error" in the memory count. At the beginning, was just sometimes at startup, but now is just when count 16 o sometimes 48 Kb, not in the same place.
This pc was the security capacitors of the Y type of the power supply broken, so at the beginning, work well until 1 or 2 minutes that trigger the differential switch at home, because there no good filtering at high Frequencies. I've replaced it and the power supply works fine.
The motherboard have the memory soldered directly, no sockets at all. What do you think?? Any ideas to avoid desoldering all the chips?? I post photo of the motherboard and the error.
Thank you!!!
