I was an avid user of the Model 100 and Model 102 perhaps 35 years ago.  I am currently cleaning out my office and and have found what I believe is a 128K external RAM cartridge for the Model 100/102, but am unable to locate any information on the device.

The device is about 3 3/4  x 2 1/4 x 7/8 inches, excluding the connector. It is marked "128" which I believe stands for 128K. There is a button battery inside, which maintains the data in the static RAM.

The connector is 40-pins, male, in two rows. I believe this plugs into to the expansion bus connector on the Model 100/102.

I would have included photos but am not sure yet if this list allows photos.

Can anyone here confirm this is an external RAM cartridge for the Model 100 and/or 102?
