Monroe 7860

[Bill Newman]

I know this doesn't count as a general purpose computer, but does 
anybody have detailed technical information about the Monroe 7860 
business calculator/printer?  I think it was produced in the early 1980's.

Specifically, I'm looking for information about the rom OS for this 
machine.  e.g. are there more built-in commands like "dir".  Maybe, 
is there a basic interpreter I can get at?

On the hardware side, does anybody know about the mag stripe paper 
that the machine is supposed to work with?  It appears to store user 
data on the mag stripe on the paper that it prints on...interesting 
idea, although limited.

Thanks.
