If so, I have two video outputs on the Carte Blanche (the original and my 12-bit color mod.) but only the 12-bit is very useful with SHR. Hmm, I suppose I could squeeze another 12-bit output in there.I mean you have two independent video outputs and framebuffers, meaning you could in theory have a 'desktop' spanning multiple displays, or use one of them for text output whilst debugging.
Okay, I understand and that should be doable, but I don't know if I'd use it.
I used to use a videoterm card to do this when developing on my IIe, though these days I just use an SSC plugged into my laptop (one less CRT cluttering up my workspace)
It would be straightforward to make your video card VOC compatible if you're doing it on a Carte Blanche.Yes, but I think I'll stick with just the IIgs features. Right now I'm wondering if it's worth it to implement scan-line interrupts.It would be cool to be able to display 3200 colour images I suppose, but there'd be very few CPU cycles left over to do anything useful on a 1Mhz 6502 ...
I agree and I "think" that scan-line interrupts are used when fill mode is used for fast animation. But I've read someplace that the //e-ProDOS handling of interrupts takes up a lot of cycles. Combine that with my general lack of knowledge about interrupts and I think they'll go on the back burner for now.
