The Crown jewel of my collection. The MB was badly destroyed by a leaking battery. But after a lot of work it is now fixed. The Keyboard was also destroyed. I fixed it by using Conductive Electric Paint . Orginal Schneider monocrome monitor. Here i am playing Digdug. You can read the details on what i did on Vogons.org
Clock and battery circuits was damaged by leaking battery. Clock did not run, and CMOS settings was not stored. Repaired by Retroservice in 2018.
The RTC is counting seconds to slow. Have tried to replace crystal in 2024.
In 2025 i re-did some of the repair that i belied was wrongly done in 2018. By studying new pictures of the PCB i found that the previous fix was wrong. Removed bridge (blue) and added a new bridge (red). This is in accordance to how the PCB was before battery leakage. Time is still running slow.
Note that date is correct, and clock (still slow) works fine in original EuroPC boot disk., when when using other MS-DOS time is always 00:00 (but date is correct).
