Hi Michal,
I uploaded the 8088-cursor patch for the 0.67 version already to github.
You can add the code for general - If no v9958 card is installed - that
doesn't matter.

My routines need only a few cycles - dual monitor with both cards has nearly
the same speed as without v9958-card.
Commodores print routines in the kernal are extremely slow !!!
They delete the screen by printing 25 lines with 80 chars and bank switching
for each character!!! Totally crazy!

The v9958 card sits behind the 8088 cart - it will fit with dual drive - but
where to place the ram card???
I decided for a 2732 because it is smaller and 4k is enough for the
diskrom-slot. 2732 are in masses available for cheap prices - I have a lot
of them... - not to compare with the rare 2532!

I can try to build a layout with 2764 as alternative pcb tomorrow.
