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
side.
Ideally, the source box would have MD5 or some other
hash
available so you could gain some reassurance that the
received image agreed with the sent image.
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.
