Watch out for the listing that's available inside the wonderful
book, INSIDE COMMODORE DOS, fails its own checksum...  There are
several places where bytes have to be changed around, in order
to get the checksum to appear, and work right.   If anybody needs the
complete 1541 source code listing, a fair amount of it commented, they
can ask me for a copy, or maybe pick one up from Steven Ho's site.
