Justin; Yes. Having the room, the various TDS 48 revisions had software to read most instruments up to the date of manufacture. The TDS 41 system had 3 ROMs. The Road Stake / Instrument Module had a few very useful routines that didn't fit into the first Survey module and the rest of it was filled with triggering programs for various guns. They sold several versions of that because there wasn't enough room to put them all in, and few companies had more than two or three types of instruments.
