Thanks for the pictures. I did see where it had something glued to the bottom. This one also had all the pins flattened over. No doubt because the cardboard was missing.
I tried to shim it up 2mm to 2.5mm but if it is high enough to not get stuck in the socket it pops right out. The electrical connection even when it is ‘stuck’ in the socket is also poor. I can wiggle it and get it work well enough for the SR menu to pop up but when I try to select any one of the 4 programs it locks up. I’m really surprised that the PCB and a cardboard shim was all there was too it. Has this ROM been dumped? I may go ahead and pull it off the PCB to try and dump it to at least confirm the EEPROM itself it good. Thanks for your help.

GregS <>< Dec 19, 2020 5:47:48 PM Jeffrey Birt <bir...@soigeneris.com <mailto:bir...@soigeneris.com> >: 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
