Hello! I have this IBM 5155 for a year now working perfectly and suddenly during power on I get one long beep and then two short ones, indicating a problem with the cga card, and then garbled text on the screen

The attachment CA171DA4-ECC0-4DDC-990D-B14774FB30BF.jpeg is no longer available

Note that the character rom is different than usual, having a memotek chip (probably with Greek characters since this was found in a Greek factory)

The attachment F5DC00C6-E162-489B-A0B9-732F15D653B2.jpeg is no longer available

Any ideas how to proceed with this?😕

Ok false alarm i just cleaned the slots better and now its working again😁
Another issue that i have though is that the 8088mph demo doesn't run (either from floppy or sd2iec)
It prints out thanks for running on original hardware and then the cursor blinks for eternity

8088MPH requires standard original IBM CGA card not modified like this.
