The BMC’s ROM is copyrighted RVS, Rasso Von Schlichtegroll !
This is a very good surprise, isn’t it ?
Then we have a very nice software to drive the BMC hardware.
The system brings us these new instructions :
MC-12A Basic instructions and codes

The last two (POSTLOAD, RVSLOAD) have special functions.
RVSLOAD loads a sample program originally stored in the ROM :
(Thanks to my new tools for the CE-158 with syntax highlighter)
But if you use POSTLOAD the program is bigger !

As a big bonus, here is the user manual for the FORTH language :

Next time we will discover the MC-12A technical side.
This will be a little boring but necessary.
