Sure I've seen it it did not run anything modern os wise. The MS DOS based control computer at my dads previous work place had an uptime of what was close to forever. We are talking stability in the range of ten to fifteen years. It ran a climate computer system control program and the control software newer crashed. Because MS DOS it was single tasked and the control program was very stable. At the time there was little computer hacking activity so you did not have to update the software either. Backups was done to floppy disks and there was a reserve hotswap backup computer. For remote control you would dial into the computer via modem, first via 300/1200 baud that is 1200 bits per second. Then later at lightning 9600 baud. I'm also sure you find very good old engineering in the computers of Voyager.
