Yes the 80286 is a surprise David, particularly since it’s not stretching /MWTC and /MRDC directly from the 82288. Must be something to do with the wait request not arriving early enough in the bus cycle. Even SRDY* low does not seem to help!

Encouraging progress John,
many thanks for the update, shame about the 80286 board compatibility problems,
I have an 8088 board under construction though :-)

For those following this long project, we have made some progress in getting towards the goal of putting a VGA video card directly on the S100 bus.
More to do clearly, but progress!
