Keyboard for?

I've got a keyboard labeled "Executive Peripheral Systems" copyright
1982. What makes it strange is the cartridges that plug in. This one
has three cartridges that plug into the keyboard along with some
corresponding overlays to identify the funtion keys. The first
cartridge is labeled "Your Program" and is also labeled "BASIC & DOS."
The second is "BASIC & DOS" for use with the ApplewriterII, and the
third is "BASIC & DOS" for use with Visicalc. The connector looks like
an RJ-11 telephone connector (with 6 connections.) Anyone know what
this thing is? Thanks.
