Problem: CD32 with SX32 expansion won’t boot, yellow screen
A few thing I tested:
- Boot CD32 without module, booting
- Boot with backplane and sx32, no boot yellow screen
- Boot with backplane only, strange behavior, no boot, sometimes some glitches.
- Change jumpers, for memory, no change. (see: jumper settings)
After the basic test, I was wondering if de edge connector is still in good condition.
As we can see, some pins are bent, some pins are shorted.
Removed the pins with shorts, and bent them back.
A few pin came loose..
After “fixing” that, the backplate works.
New expansion bus edge connector
Replaced the connector and everything is working again!
