Re: Vertical Blank on Apple ][+ comp.sys.apple2.programmer Posted: 6 Days 6 Hours ago by: Michael Pohoreski Nice! Yup, one can do all sorts of neat stuff if/when you have a proper Vertical Blanking Interrupt. Fantavision also has a 10x14 px mouse cursor. I should RE/rip that mouse display graphics code someday ... Michael.

Re: accessing auxillary memory language card memroy area (thread) comp.sys.apple2.programmer Posted: 7 Days 9 Hours ago by: Antoine Vignau Hi There, I like the document @ https://drive.google.com/file/d/1Ydbw3Y6vU4ynNOwrKRuEnNT5_B3LsCvd/view?usp=sharing - Even if written in French, it explains the meaning of the different bits that select RAM vs ROM, Read vs Write, Bank 1 vs B
Re: accessing auxillary memory language card memroy area (thread) comp.sys.apple2.programmer Posted: 9 Days 17 Hours ago by: woodsworth1 Thanks heaps. Once you know then the vague allusion to swithcing banked memory area with zp and stack on page 88 makes more sense. But it is definitely not clear, and not in the description of the soft switches at all. Cheers jp

However, you need to STA $C009 to switch to aux LC, STA $C008 to switch back. Switching to aux LC also switches to the aux
