I am using a Blackjack Tele-Controller micro module made by Micromint. It has an 80C552 controller.

I am not sure if the board itself was made by micromint or not. I looked on the Micromint site and could not find any info on the module. The module is supposed to have a modem, but my particular module does not. It very well could be a custom made part, as my dad got it from his work.

There are two numbers printed on the first page of the documentation, I am not sure if it is the module's part number or the modem's part number. They are XE5224DM and XE5224FD.

I would scan some of the documentation and post it online, but my scanner is not functioning properly.
