Demo using the normal PCW driver

Program for making business graphics from Digital Research. To run the application, place side A in drive A: and side B in drive B:.

RSX

The Amstrad version has a CP/M 3 RSX attached which modifies the program's behaviour:

  • BDOS function 2Dh is used to stop the program terminating if there is a disk error.
  • Input keycode 0FCh is translated to 1Bh (Escape) and 7Fh (Delete) is translated to 08h (Backspace).
  • The code which loads overlays searches for the overlay on drive M:, and then on A: or B: depending on the number of the overlay.
  • When files are being loaded from disk, BDOS function 2Ch is used to try and read as many records as possible in one go.
