Respect!
I like the way how you show us your steps.

Respect!
This is a big step.

Hi,
this week i must got my eprom programmer, then i can burn and test also.
I hope we got more CV programmer, and not all have a eprom programmer.
And carlsson can not burn and test for all(i think)

and don't forget that a part of the Bios Interrupt read the VDP Status register BEFORE jump to your Interrupt. So the Register will be reset. But put the value in $0c. [CARTRIDGE IRQ HANDLER] FF3F: pha FF40: txa FF41: pha FF42: tya FF43: pha FF44: lda $2001 ;VDP port #1r (reset INT flag,as need) FF4...

Hi, i think you can let the music player stay in the interrupt. Is also great for the exact timing.

Wow!
going on very fast.
You ask me to test the ColeoVision multicard if is possible to access as a normal USB-device.
I don`t found a normal USB cable for that, i think my last "Aufräumaktion" was to heavy.
I will get one cable on Monday, then i test.
