That is a chart recorder. We used to use one to record thrust curves in the analog days of the 60's to early 80's. Ours were surplus. Their telemetry is likely an analog signal or two.

We went to digital about the time the PC-AT (286) came out. My company was computerised since 1978. First a PDP-11 for programs, then a Xerox 820 (CP/M 8.5" foppies) for publishing and locally run programs, then a 286 clone which ran the magazine, rocket club, 3 rocket companies and a publishing company. Then a Mac+ running Ramdisk which was not surpassed in speed in ram disc mode till the 040 came out. It also had SCSI .
