I know this is a vintage list, but at a minimum, PS/2-style bidirectional
parallel ports have been around for a very long time, so this shouldn't be
a problem. Even if you had an old XT, printer and monochrome adapter cards
can usually be modified to operate in bi-directional mode.
After that, it's just the cable and a bit of software on the receiving

CRC-32 would probably do if MD5 wasn't available, and it's short enough
that if you had to key the C source in (assuming that the SCO box has a C
compiler), it wouldn't be an onerous job. You could probably do that
while the transfer was running.
Failing that, you could transfer the tarball twice and compare the two
files. A miscompare wouldn't tell you which was bad, but it would at least
indicate that something had gone wrong.
