I’m not a expert at these machine but I have one and been trying to find a new board for 6 months now it looks like you are missing the chip for the reels and memory chip here is a picture of mine these are nearly impossible to find parts for so if you decide to part it out let me know

Hi and many thanks for your reply.
Refering to the manual i have a 32k eprom Version (Orange Label) 1 eprom and one decoder and the jumpers are soldered correct. If i interprete this manual correctly the 32k Orange Label Version has 2 Chips. 8k and 16k versions use more
I agree there is almost no real detailed technical Information in the Web.
Do you have a working machine too or just one with a defective Board?
ID like to know what the machines reaction ist when its started without driver Board (Controller Board only)_ with and without small mpu Board to get a direction on which Board i should continue my troubleshooting . What wrong with your Board and what are the Symptom? Best regards Michael
