As usual, a picture of a benchmark :-)

Picture is quite nice and filling the screen perfectly (it is a NEC 1990FXd connected via your ST2VGA adapter)

This is with 16MHz and STORM active, but since Gembench is running from the Diag Card, it is running from ST RAM

The NEC is also working with 15KHz in low and mid res.
Low res much better than mid…
Repeated the benchmark in mid res

Seems, the GEM and VDI performance is different, depending on the resolution…

Need to set-up a IDE adapter next…

Ok, I call this build „done“ - for the time being…

Added a TOS/IDE Card I had laying around.
It is called TDEaL and contains two TOS2.06 EPROMS (soldered), which I deactivated, so only the IDE port is active.

Had to mod the Gotek stand a bit to make it work, since the TOS/IDE card was physically blocking nearly everything because of its layout.
Had to use IO Port #4 on top of the STORM for the IDE card and connected the CF reader by ribbon cable and a male/male adapter

Finally installed NVDI and made the obligatory benchmark :-)
