[Coco] coco cartriges

[didier derny]

I got a  coco2 cartrige on ebay.

 

I opened it, without breaking it J 

I found inside  a small board that can contains  2 x 24 pins roms

 

On my cartridge, there is only one rom installed..

 

Are these roms 4k or 8k ?  any eprom compatible with these eprom  ?

 

Marking on the eprom:

 

SCM90706P

TANDY  C 1981

8070033

M 8140

 

Any way to use this cartridge to install a rom to start drivewire ?

 

 

Thanks
