My first job in high school was at a company with the entire business running on SCO Unix. I want to say OpenServer 3, maybe? It was essentially a terminal server with dozens of Wyse 60 terminals attached.
Anyway, as a Linux enthusiast I promptly setup a RedHat 7 install on some old hardware they had lying around. IIRC correctly it was a low-end Pentium but it could handle a PCI 100mbit ethernet card just fine.
Anyway, the goal was to get data to/from the SCO system to something with a TCP/IP stack (RedHat machine) so it could go somewhere - samba shares on the rapidly growing ethernet network, maybe even the internet!
We ended up using UUCP over serial, scripting, and cron jobs to push/pull from directories on each side. The RedHat machine was promptly connected to a 56k modem to do dial on demand and IP masquerading for the ethernet network and uploads of specifically formatted files from the SCO system via FTP to vendors and partners.
Fun times!
