My first brush with "DTP" involved a teletype, an acoustic coupler dialling up an ICL mainframe, a PMT machine and a Xerox the size of a Ford Escort. The latter used to break down at least once an hour. If we missed our "slot" on the mainframe it meant a 12 hour wait for the next one, just to format some text!

I never used Ventura, bur I did use Deskpress/Timeworks with GEM on an 8086 (5" floppies) for a couple of years. It was actually quite quick - until you came to print, then it was around 1 hours per A4 page :)
