You don't really need an add-on board to do that, just a MEMCAL with
appropriate self test software.
The peripheral board would allow you to hook up a terminal emulator and
get a command line interface to the testing software though. This would
let the software promt the user to perform various tests ("Ground pin
D10." "Hook a test light to F1.")

In RPN, to add three and four: 3 4 +
No documation.
