TT and Mighty Mic 32b

Postby damanloox » Thu Apr 12, 2018 2:41 pm

I have TT and wanted to install Mighty Mic 32B but all I'm getting is.. 2 bombs.
I tried another fast ram board I have and it works perfectly fine with (with the same simms).
Mighty mic seems to be ok - the "patch" wire (which I believe is standard on rev b) also looks OK..
Any idea where to start troubleshooting? I only have 16mb in bank A (jumpers are set correctly). Tried with simms in bank B (again - jumpers set according to the manual) - same thing.
One more thing - during fast ram test (initial boot) i'm getting X-es (instead of "regular" - characters)...

X means RAM error. Maybe one of the datalines are bad.

You can start by tracing the datalines from the SIMM sockets, then verify continuity.

Before whipping out the multimeter, it’s probably worth re-flowing the solder on the simm socket(S). Cold solder joints through mechanical stress of inserting/removing Simms will be the most likely cause of failure.
