I expect the major signals in the video slot which are not on the connector
on the back is the raw 4 bit per color digital values.  To reproduce these
signals from the RGB port would require 3 very fast 4 bit A/D converters
which operate at video speeds.  Now, I'm not up on such hardware but I expect
these would probably be expensive.  Microway already makes an adapter which
fits under the Denise chip and allows you to relocate your FF out of the video
slot and into a more convenient location freeing up the video slot in the 2000.
I had thought that the 500 and 2000 Denise chips are equivalent.  If so, a
more promising hack might be to use this adapter and some sort of external
box to provide the FF capability on the 500.
