The Burroughs B6xxx/B7xxx (including the B6500) MCP is NOT written in
assembler.  There isn't even an assembler for the machine.  It is (was)
written in ESPOL, a systems programming extension of ALGOL 60.

Since the current MCP (for B5900/B6900/B7900) is around 500,000 lines,
it is very unlikely (to say the least) that the B6500 MCP was larger.
My guess is that it was on the order of 250K lines, but that really
is a guess.
