Timing Loop For Slideshow Suggestions Wanted

Show all headers | View raw

I have written an 8 bit ProDOS slideshow for SHR images in Aztec C. It 
currently advances on a keypress.

I would like this to work in the following configurations using a common 
timing loop with an auto advance on seconds:

1. Normal GS Mode
2. Carte Blanche with Charlie's SHR Mods - Apple //e  and GS Both
3. VOC Apple //e and GS Both

So what do I do?

1. Use the NSC (not everyone has these)
2. Use a config file that can be edited for timing loop values.
3. Use some other hardware feature for both the //e amd GS

I am leaning towards a config file because it is universal. Does anyone else 
have some other idea that can be used in all configurations?

On the IBM-pc I would have used an interrupt handler at 0x1c and a timer 
resolution opf 18.2 ticks per second.  This would have worked up to and 
including Windows XP.

However methinks the universal approach of a plain old timing loop is all I 
can do with the Apple II.
