In the 1980s when games were on cassette tape we used to go to either a recording studio or directly to the duplication plant. We'd take the computer with the mastering software and plug that into their reel to reel 'recorder'. I think it varied but was 1" or 2" tape usually. We'd then run some cassettes off that master to validate they loaded, some of the copy protection was picky about the duplication quality and speed. They'd then start production and the finished product would be on the shelves in a week or two at most. It was a fun and very interesting time visiting all those places. I went up to Telford once and was stuck there for a while as there was a mastering problem and we had to play with the copy protection. Most of the times it was a place by the A4 near Chiswick/Hammersmith.
