It's done!

The v9958-card is finished and I just doublechecked mode 1, mode 7 and
textmode 2 - it's fully working with 128kB vram ;)
I will upload the files on github and if someone needs help with
smd-assembling or GAL-programming - write me a PN.
The card runs with v9938 or v9958. In the 2732 eprom are the two cbm2 font
sets converted to 6x8 chars. The fonts need only 2kB. I'm just writing a
power-on intro for the other 2kB.
I also modified the kernal 04a to use my color-card including a solid
software-cursor. This works with nearly all programs, because they all use
the bios routines (except Space Chase). You have dual display on original
and color-rgb-monitor.
The card fits in 6xx and 7xx machines and it should be fit together with a
dual internal drive.
It also works with the 8088 card (only bios int). I modified the 6509 code
on the 8088 bootdisk to get a solid software cursor un the color monitor.
The Yamaha VDPs support up to 512x424 pixel interlaced, 19000 colors, 32
sprites and accelerator commands!
