Cinematography : Archive 81 - and a question of cameras by Mark Giacomin

Hello!

I really enjoyed the series 'Archive 81', and I just watched a short video about cameras that appeared on the show (link below).

I know absolutely nothing about cameras, but was wondering if someone that does could help me out with some queries.

1: If I wanted a character (much in 'Archive 81') to be specifically using a retro camera from the early 1990s but in contemporary times, would the camera have the facility to upload content directly to a laptop rather than a tape i.e., would there be a specific cable?

2: If a character finds old footage tapes from the 1980s (in the UK), what type of camera could have been used and what type of tape would it be? (NB: Probably would want to feature the use of the camera in modern times so, as above, could someone use custom cables to download content?)

3: Similar question to the above, except from the 1960s (in the USA), and, whether it would make a difference if the military had shot the footage?

Many thanks!

Mark
