Hi,

Straight to the subject.

68000 + KS3.2, I get the insert disk screen.
68030@60MHz + KS2.04, I get the insert disk screen.
68030@60MHz + KS3.2, I get nothing.
68030@30MHz + KS3.2, I get a guru meditation error about an illegal instruction.

I have not tried any other frequency but is there any known issue between 68030-TK2 and 3.2?

Thanks!
 
Can you please install resistor networks RP106 and RP107 (4.7k bussed) and then test again?
If you are sure and it is a known issue, I can order them and try.
What is the value of these 2 resistor networks right now?
 
@jokersad i fitted both with 4.7K resistor networks and it works! At least the 3.2 insert disk screen appears.
Later I saw a A500 BOM list and it was clearly written that for 3.1.4 and above, these 2 resistors must be fitted to pull-up the signals.
I appreciate your help 🙏
