Diagnostic Cart help

[coonsgm]

Greetings Atarians,

I got the following output from the diagnostic cart through VT32 on another ST. The ST doesn't boot and looks like it has a RAM issue...which the cart seems to output, but I would like some other eyes looking at this first before I take any action.

The way I am reading this based on the troubleshooting guide is that Bit 13 is stuck high on read, but I'm not sure what the 92 signifies.

Appreciate any help!

Thank you
