Hello

it seems like a bunch of people are doing Apple II XMAS demos this year.
So here's my entry:

Notes and disk image here:

It does some cycle counting and such, and fits in 8k.

Music if you have a Mockingboard in Slot#4.

Graphics may be a bit glitchy on a II/II+ as I'm doing a midscreen
lores/hires switch. Looks fine on a IIe.

Firstly, thanks for the demo.

Secondly, I’d like to see all your works support the Mockingboard in any
slot.
I guess cycle counting code makes this a little more difficult to
accomplish.

One way I helped accomplish this for (a future version of) Total Replay is
to detect the slot then patch the music routines to hit the detected slot
before execution.

Here’s a slot detection routine:

Here are some examples of patchers:

https://github.com/roughana/4cade/blob/master/src/prelaunch/ pitfall.ii.a

https://github.com/roughana/4cade/blob/master/src/prelaunch/ lancaster.a

Let me know if you need help.

Regards
Andrew

It's a bit late, but I've updated the xmas2019 demo so it should now
auto-detect the Mockingboard slot.
http://www.deater.net/weave/vmwprod/xmas19/xmas2019.dsk

Try it out and let me know if it doesn't work.

I've also updated my pt3_lib sample code to support auto-detect, so
going forward a lot of my code should support it. I haven't updated any
old projects yet, except for the pt3_player.

I look forward to that.
