Imperious you are right, this will be the next step.
Are you using the small vga RAM heatsinks?
I'm using a 9 VDC 2A stabilized power supply and the 5v 7805 regulator inside run cooler than with original power supply that is giving around 10-11 Volts. A good idea could be replace the 7805 with a switching version that doesnot need heatsink.
I was also thinking about using a small external ac adapter 5v 2A but this will need some mods on PCB.
The 8501 without revision number is the working one, this was on a C16 from Germany that came with the repair note replacing CPU on 1990 and repair seal intact.
