I have the Prolog M900B and manual. ANAICF the M900B is the M900 with the
"Buffer option". (The big white silkscreened model number on my M900B still
says M900, so if your's has a buffer then it probably is a M900B.)

I don't have a scanner here but can look into scanning the manual sometime, just
don't hold your breath. In the meantime I'm happy to attempt to answer some
questions about it's operation. The user interface /is/ rather awkward.

Note there are a lot of options, mostly with regards to various communication
interfaces (parallel/TTY/RS232/flow control/baud rates). Some of the installed
options may be listed inside the plug-in compartment, but if you want a
reliable list you have to look inside the case as to what is installed in the
14 sockets for the 1702 firmware EPROMs (it's a 4004 running the show).
(If you make a list I should be able to tell you what you have. Mine has the
RS232 option and I have managed to transfer data to/from a computer.)
