makeasm.pl will create vendas11.asm, which, so far, includes every byte
of mapped.asm as a FCB command. This can be assembled and compared to
vend.bin with a "make test".
It appears that mapped.asm had lost some lines somewhere along the
line - fixed.
"masm" is a version of the as11 assembler I found...
