I am no expert on the SuperGrafx, but, from the
SuperGrafx Extreme websiteFront
* controller/pad port
* "S Expansion" aka "Special Expansion" aka "S EXP"
"If you look at the SuperGrafx from the front, there are two
obvious items on the right hand side. The one to the left is
the S Exp port. As it turns out, this port never had a use.
The planned uses for it remain unknown. To the right of
the S Exp is the controller port. This is where the
SuperGrafx controller plugs into the system. For
multiplayer games, the multiplayer adaptors would plug in
here as well."Back
* EXT Bus aka External Bus
"
Taking a look at the back of the SuperGrafx, two things are
visible. To the left, in shadow in this picture, is the mode
switch. This switch determines whether the SuperGrafx is
in SuperGrafx or PC Engine mode. This makes a difference
when playing games like Darius Alpha and Darius Plus.
The second feature is the external bus. This port was
designed to allow the SuperGrafx to accept add-ons, such
as the Super CD-ROM2.above pictures originally from EGM Number 8, March 1990, page 53
the only major pheripheral for the SuperGrafx other than the CD-ROM interface, was the "Power Console" controller.
not sure what port this used. either the controller port or the S exp port on the front, because this Power Console controller slid over the SuperGrafx console
