This will be of interest only to people who have programmed the MEiKO
Frame Grabber.

After analysing my code I have noted that the MEiKO MK027sys is slowing
the frame grabber down. I've had a look at the code and hacked all the
supervisor bus code out (there were loops in this that just polled
registers waiting for something to happen). This didn't seem to improve
things as much as I would have liked. So I went on to rewrite MK027sys.
This has proved difficult as I have no software documentation for it and
the hardware reference manual is incomplete (missing register
descriptions). I now have a hacked MK027sys which doesn't work ! And I
can't see why.

The question is has anyone written a simple peice of code that just
grabs a frame, without using MK027sys. Any help would be appreciated. 


Many thanks,


Andrew.
