- They could hardly say anything else, or who would have bought the
- machine. Who would have developed for it? "Make my own system

- This is why I suggested:
-
- a) Running the disk-read task at a low priority
-
- b) Make your game task wait (using the OS) for the frame
- refresh, rather than polling a hardware port or installing
- a custom VBI server and busy looping until the interrupt.
-
- Okay, so I haven't personally tried that particular setup (no need
- to), but I don't foresee any great difficulties with it.

- This was wrong, and just because CBM let it happen doesn't make it
- right, or we would have to go under the assumption that none of us
- were good enough to deserve the 3000+ and similar obscene
- mismanagement antics.

- Well, I'll just have to get a hold of it and try. ;-)

-
- And why should the gameplay not pause, even for a moment? A game that
- doesn't stop only feels drawn-out and tedious, no matter how fast or
- impressive the graphics are. What's that PSX game with the
- delta-shaped racing thingy... I can't remember, but the point is that
- it is quite boring, even though the texture mapped graphics float past
- at 50fps with no glaringly evident shearing of texture joins etc.
-

-
- This is hardly a point that needs to be made, the stock A1200 should
- come with 2 megs of Fast RAM with the 2 chip, and I believe it's
- shortsighted to think otherwise.

-
- I'm hardly likely to apologise for wanting to keep my Amigas as
- productive machines rather than screen-savers that crash a lot. For
- all it's 14MHz 68020-ness and meagre RAM allotment, the A1200 is still
- a hell of a machine, and I don't see its limitations as being an
- excuse to start bumping hardware to make a point.
