- I understand there are a lot of AMOS demos about. Even compiled, I can't
- imagine they'd be fast...
- C should be OK for most parts of a demo, but I'd recommend learning 68000
- ASAP simply to get the max.
- When you use the blitter you should notice a hair-raising increase in speed. I
- would guess (I don't know how well your compiler works) around a 2000% increase in
- speed. The 68000 uses manymanymany cycles for its instructions (averageing around 6,
- isn't it?) whereas the blitter uses two per word fetched. Typically.

- What's difficult abour spelling 'algorithm'? :-)

- It works (mostly) on my A1500 w/1M chip, 2M fast, 2 Floppies, GVP SCSI
- board + 52MB drive, but crashed after a while. I understand it works better on my pal's
- A600.
