Hey, I have a Hot CoCo magazine from September 1985 with the cover 
article:  "Cram It with RAM:  256K Memory Upgrade!"

It's not from J&M, but "J&R Electronics".  It is called "The Banker" and 
consists of a PC board, a replacement SAM, some TTL, and RAM chips.  
There is a schematic printed on page 29, and mention of Flex and OS-9 
support as "possible future offerings".
