Hello,

we have mega-problems using the cartridge port on our MEGA ST2 and we think
it is a common problem for all MEGA's with a boardrevision higher than revision
4. We use the cartridge/ROM-port to read data from an ADC to digitize
satellite WEFAX-pictures from METEOSAT. The soft- and hardware works fine on a
MEGA ST2 with a revision-4 board or a 1040STf, but it crashes (with 4 bombs)
on any MEGA ST2 with a revision-5 board.

Our dealer (ECD delft) and ATARI Benelux (Netherlands) couldn't help us (yet?),
so we would like to ask if there is somebody on this net with enough inside
knowledge to help us. We would like to find out if there is a software or
hardware difference between the mentioned boardrevisions, and if so what these
differences are.

                                        Aad & Jos
