Yes, it should work - or at least the directions and buttons B & C should work without modification. If you swap pins 5 and 7 then the right software can read all buttons.

It can be done quickly enough to look nice with low-res HAM6 images (Here's an AMOSPro demonstration - http://retroramblings.net/?p=25) but I think it'd be too slow with HAM8.
