SuperROM - 

 

Working on an M100 now that came with a SuperROM that had stuck in the
socket and the socket managed getting it out. Socket replaced, but I am
confused as to how the SuperROM (SR) was ever intended to fit properly.

 

The SR gets stuck as while the Pin1/28 side is held up from the bottom of
the socket by the pin 1 tab on the SR PCB, the opposite end drops down so
far that the PCB falls below the bend of the contacts. This lets the
contacts spring out over the top of the PCB and thus it is stuck.

 

If I shim up the SR enough to prevent it getting stuck then it pops out very
easily. It seems to be a very poor design. Perhaps there is some part of
this one that is missing? I could not find any images on the web that
clearly showed the SR board to compare to though.

 

The contact is also really poor, sometimes it will make contact in the
socket and sometimes not. It may be that the PCB was damaged when it was
wrestled out. 

 

Lastly, has this ROM been dumped? If not, I'll pull it off the PCB and read
it.

 

Thanks,

Jeff Birt
