I've picked up this CDTV some time ago, but didn't have DiagROM to test it properly. It is running perfectly fine, all features. My diag chip arrived this morning, and when I get to Extended Memory Test it completes with no bit/byte errors, but throws an IRQ error like this. EDIT: there are some errors?
Is it due to fact that CDTV has extended ROM, and access to CD at boot or there is something wrong with the machine? How to get started to decoding these error codes, if I want to learn?
I wanted to bring something up, as I just tried to fit in PiSTorm and had random address errors on buptest tool (it writes garbage to chip ram and reads it back). I replaced PiStorm with stock CPU and ran DiagROM again. What does it mean and what are these artifacts on the screen towards end of the test?
