Yup, I remember those.   At one time, Diablo Systems was going to use
those on its "Merchant" project and had even worked out a DIBOL for the
Intel 8080.

Later MCBA re-wrote the applications in DG Nova BASIC (IIRC).  At
Durango, we picked those up, wrote our own multi-user BASIC for the 8085
and 'ported the MCBA apps (AP, AL, GL, Payroll and Inventory) to our own
system.  Later, we ported our BASIC to Xenix and ran the same
application on an 80286/80186 multi-terminal box.

I still have the source code for those.
