The DART scanner for DMP printers

A scanner for the Amstrad DMP 2000/3000 printers from Dart Electronics.

Reviews

The Dart Scanner was reviewed in Amstradbladet 1987, Issue 3, page 8 (Danish)

Technical

Uses port FBEFh, the port seems to be read-only. 

 Bit2 Carriage Returned/Parked (0=Wait/Head Parked, 1=Scan/Head Moving)
 Bit? Scanned Pixel Color      (0=Black, 1=White)

Scanning is done in single scanlines (one pixels height). The scanning procedure waits while FBEFh.Bit2=0 (which probably indicates that the head is in the left-most position, or that it has just leaved it, or so). The horizontal "dot clock" is implemented as software delays. When scanning a black dot, one or more bits in Port FBEFh become non-zero (not sure which ones; the driver software simply checks "IF Port[FBEFh]<>FFh THEN PLOT pixel").

Observe that the manual includes some patches for usaging the scanning software with different printers.
