Continuing this thread... I just installed NewTek's DemoReel #3 on my Amiga 1000, and when the Dynamic HiRes image is supposed to be displayed, nothing happens - the demo moves on.

This is an NTSC Amiga 1000 with 512K CHIP, 2MB FAST, and EHB is supported, here.

Should this machine be able to display dynamic high res images?

On the Atari VCS, you had to do this. It had no concept of a frame buffer, so you built the display up manually on each scanline.

Now that's hardcore. :)

I just did a very quick interview with Rhett Anderson who made SHAM. He said the viewer slowed the system 10-15% but was not intensive. His first viewer was not multitasking friendly, and so people (including me) assumed it took loads of system resources. Apparently not. I am working on a post to detail the back and forth with the author.
