There are no sequels to Rendezvous with Rama. Nope, never happened. Just an ugly rumor.
To me, the "real" RoboCop is the original film and the 1994 TV series (whose pilot was adapted from Neumeier and Miner's rejected RoboCop 2 script, so I consider it more genuine than the Frank Miller nonsense that followed on the big screen).
And I consider Terminator to consist of the original film, T2, and The Sarah Connor Chronicles.
For me the Robocop franchise begins and ends with the film 1987 Verhoeven film Robocop
Anything thing else with that name doesn't exist IMO
