Yes, and an A1000 running a 2/4/8/16 color anim would be OK depending on the animation+compression method. 32 colours and Ham6 would be more difficult but it can be done. I achieved around 10fps but forgot to mention that I had some fast RAM and softkicked to KS2.0 - but it was a 7mhz 68000 A2000.

I really doubt it unless you upgrade the 7mhz 68000 CPU. The hard drive speed is not the biggest problem - it is the CPU. I added a 28mhz 68000 accelerator to an Amiga 2000 while testing animation playback and the hard drive read/write increased dramatically. This was using an old A590 interface with a 100 meg scsci hard drive (not an 'XT' drive which may be too slow).
What about if we did the old ST trick of just blitting single pictures into memory from a very fast CF card....then you need zero CPU time except to actually display an image in sequence and then the next.
