Advanced DTP was a homebrew desktop publishing system released on the CPC in the early 1990s. It was written by Geoff Smith, and retailed for £5.
Advanced DTP was very similar in intent and execution to Alan Scully's Pagemaker Deluxe, even down to the use of the same Amstrad Computer User type-in to achieve a vertical screen. However, the only comparative review published (in Artificial Intelligence) judged PMD to be the better program.
