I also worked for a retailer with a very similar setup (I wonder if it was the same one). It was amazing how many terminals you could sling on to a 386/20 and still have the whole thing work. The retail software was custom-written C that used a UI toolkit/library for the screens, but the name of the toolkit escapes me. I was in support at the time and didn't actually code the software, so I have no problem saying that it was a hot mess. :-) I managed to grab some SCO Xenix installation floppy disks when I left (they had moved on to Netware/MS-DOS at that point, so the disks were just going to get thrown out). I still have them around somewhere...
