With the new IMAGE_PICTURE device I've started looking at Digitisers. There are three such devices for the BBC that I'm aware of:
- RH Electronics Video Digitiser (1MHz Bus)
- Watford Electronics Hand Scan (1MHz Bus)
- Watford Electronics Video Digitiser (Userport)

I'm currently looking at the RH Digitiser, as the original developer is available for technical queries.

Low resolution (4 colours)

I'm having some row counter issues in other resolutions, so not ready for submission yet. But am impressed with the results so far.


BBC Model B, ATPL Sidewise, Acorn Speech, 2xWatford Floppy Drives, AMX Mouse, Viglen case, etc.
