When I first started, a teleprompter was mainly studio only. I used my client’s crazy proprietary “remote” teleprompter system that would give a composite video out, but only display to the operator 3 tiny lines of text. So, I learned to be veeeeery focused. As a bonus, if you went backwards, it would crash.
When I got fed up using other people’s gear, I bought my own system. It was an Apple Powerbook 180, running Quickprompt by Marietta Designs. Prompting with a laptop computer? That was high tech! I fed it into a MirrorImage TP-140, a tank of a CRT (cathode ray tube… the non- flat panel monitors) teleprompter that was a very reliable albeit heavy system. It required a Magliner dolly to transport the massive Thermodyne cases and counterweights, but wow, no downtime, ever… definitely the early stages of portable teleprompters.
