Typerwriters won't help.

I bet that now, CIA can do it much more stealthily. And I also think that it is pretty hard to make these 1980's workstations secure -- that old DOS software was full of vulnerabilities, and it has no modern protections at all (usernames, kernel mode). I remember back at high school we had "1980s style set of workstations each accessing things from the floppy drive." and they were full of viruses. And once you have your code on target computers, you can exfiltrate data pretty easily (emit right patterns with pc speaker, memory access, display, etc..)
