Does anyone know if there exist 16-bit mono graphics/printer cards (i.e.
Herccules compatible cards with 16-bit connector).

Many people (including me) use such (8-bit) cards as debug screens
together with VGA or SVGA cards. Unfortunately, these 8-bit cards cause
the VGA/SVGA cards to switch to 8-bit mode too, even very sophisticated
boards. This is because of the design of the ISA bus, when two cards
with different width use a common 128k segment in the address space
(here it is A000-BFFF). This causes performance of the VGA/SVGA to slow
down a lot. Therefore, I would like to know if there are 16-bit Hercules
cards available on the market.

Thanks for any hint,
Kai Uwe Rommel
