Don't expect too much,
the W95 drivers were just warmed over W3.XX and caused my model 95 to run
in DOS mode. Maybe the NT drivers are better, I don't know as I have never
tried them. The W95 drivers do support the 6091-19 as a menu option, which
is kind of nice.

The MC1608C/11 is a 2 MB graphics card capable of driving
frequency monitors. It is no suprise that the Cornerstone monitors
the time (1993/4) are supported, but – pretty surprisingly – also the
whole of the 6091 series by IBM.
Selecting the monitor is done via a set of jumpers in
the JP1 position
of the card (top right corner).

AdapterId 80A6 ImageAccel Display
Primary or Secondary Video Adapter
Choose primary if ImageAccel is the primary display, otherwise
secondary if VGA is the primary display. (HPE:
If you select the standard of <Primary> for the video adapter, you’ll
see all DOS based messages on the monitor attached to the ImageAccel. <Secondary>
means that you use the ImageAccel only for HiRes output (which would require
another monitor attached permantently to the BVA).
I/O base address
Choose a 2 byte I/O block with no conflicts
2010 (2010-2011), 4000 (4000-4001), 4010 (4010-4011)
Memory base segment address
Choose a 8K memory block with no conflicts.
0DC000 (DC00-DDFF), 0DA000 (DA00-DBFF), 0D0000 (D000-D1FF), 0CE000 (CE00-CFFF),

It can't share interrupts?)

Fixed Frequency Color Monitors with ImageAccel Video Controllers.
Monitor - Color 21/76, Color 20/70, Color 19
The Color 21/76, Color 20/70 and Color 19) are fixed frequency
color monitors. These monitors are not compatible with standard VGA video
controllers. Standard VGA video cards require a monitor that operates at
31.5KHz horizontal scan frequency with a 60Hz vertical refresh rate. These
monitors have only been tested using the following ImageAccel video controllers.
Color 21/76 ImageAccel 1 - MC 1608C/11
Color 20/70 ImageAccel 1 - MC 1608C/11, 1608C/12
