Zorro II RAM disappears and proc 7Mhz after 20 mins or so

Post by nadoom »

Hi Chaps,

First time I am posting and have been lurking for a while. I built a TF530 a while back that was behaving very nicely! thanks @terriblefire for your hard work.

I recently started to get an issue where by once the card is warmed up and I reset the machine the processor then runs at 7Mhz rather than 50Mhz and the fast ram is not available, oddly enough the 2MB fast ram in the GVP Hard card I have disappears as well.

I have run Diagrom and it shows 2MB fast but in the config it doesn't detect the zorro card.

I am thinking a dodgy solder joint, bad ram , or a borked CPLD, but would really appreciate any one elses idea on the matter to help me narrow it down. I have ruled out an issue with the A2000 as the original 68000 always shows the 2MB in the zorro card using diagrom when its warm.

Cheers

Sounds like the reset isnt resetting the autoconfig?
