Gianmario visited my place tonight, and I had a look at his computer. I should have paid closer attention to his description, as I was surprised to find the "monster PLA" chip on the board (for which there might be no other replacements than the do-it-yourself project on FUNET). However, you could blindly type commands, and the memory seemed to be okay: I loaded a compressed executable to the computer via the C2N232 interface, and it decompressed and started okay, except for the graphic data. The 16k video bank selection was obviously at fault. So, I desoldered pins 2 and 3 of U2, the $dd00 CIA, and the correct graphics started to appear (not all the time, because the -VA14 and -VA15 lines were now floating). Afterwards, I measured that pins 2 through 4 were all 0 volts, although they should be 5 volts. So, the $dd00 CIA is broken, and Gianmario will have to replace it.
