Just a note for fun...
You can in fact fool the Amiga to show sprites in the border as well by
updating the spritepointers manually instead of with the copper... 8^)
We did that in an intro about a year ago (Total Perspective Vortex/Frantic)
and I can't recall that I've seen it done ever since. Does anybody else
know if it has been done? (not that it was any difficult, but still a
very nice effect).
(For those who didn't know it, using 8 sprites disables a word from
each side of the screen. Time used by the copper to update the
pointers, I guess. This is the area that can be eliminated)

You wanna make the 64 do something it isn;t supposed to?? THere was like
a 4 or 5 byte hack (once you set up the raster interupts) where if you
changed your raster irq line number, as part of the irq routine, increasing
it by 1, (to the next line) it will move the screen down that one line...
Now, was Commodore planning on that one? No, I quite doubt it...
Now you can also make the 64 sound like it has more than 3 voices...
Thats not that hard either.. Kinda follow the same route as on the
Amiga (I would believe, I could be wrong..No flames please!)... 
The 64 had ALOT more hardware "hacks" than you can imagine.... Trust me...
I've done some of them....

 I would like to start writing programs from my amiga. Simple games, utilities

I can obtain compilers/resources by FTP? Also a big plus would be if there are
plenty of books available on programming in said language. I have a good
 working knowlege of Pascal, but pascal code is long a and laborious...

Hmmm.. Thats funny, cause I was about to suggest the same thing...I remember 
back on the 64 where a EuroChart started, but it went to include other 
countries also... Including US... Which is REALLY odd, cause of the differnet
PAL and NTSC... But it did work... SOmeone can start it again.... WorldChart,
have it main start out as alot of Non-Euro, but some some in there... The
WORST thing we could do is make it seem like we;re ANTI-Euro... I think
that would be a big mistake....

Just a little add to your article...
It's actually possible to show one bitplane using sprites+copper...
But only if the resolution is 4 planes lores MAX... Or else the timing
is ruined....

Yes, I agree with you. A comp.sys.demo.coders newsgroup would be nice.
Are there others who would like a newsgroup for demo-programming?
As for the plasma-routine, I don't think it would be very easy to do
on a PC since it's made mainly using the Amigas' COPPER. But as I don't
know very much about Intel-assembler or GFX-cards I really can't say.

On the contrary, I find PASCCAL programming to be fairly easy, especially
compared to C.  I use HiSpeed Pascal regularly for woork at university.  It is
very compatible with Turbo Pascal for the PC's - which is both good and bad.
Good, because the code you write is portable (which I consider a big plus,
since I'm supposed to hand my code in in Turbo Pascal :-) ).  Bad, because
under DOS 1.3 you're program will ALWAYS open a window if run from workbench,
because Turbo Pascal always needs somewhere to write to.  Not a problam with
DOS 2.04, because the window only opens when you writeln or readln.

HiSpeed Pascal (HisSoft corporation in the UK) can be purchased from
Creative Computers for about $90, comes on four disks, and has two manuals.
One is a general reference manual, the otheris a technical reference manual.
The four disks cover version for DOS 1.3 and 2.04, as well as 'units' (similar
to C head include files) for both versions of DOS.

If you have any questions about HiSpeed Pascal, email me.

I assume you have the fat agnus... (you must :)

You may be able to figure this out for yourself if you have the schematics.
(They should have come with your "Introduction to the Commodore Amiga 500"
book.)  Find the page that has Agnus on it (may be "FANG" or "Fat Lady"
depending on version.)  Find pin 44 (Labled "Test" or "NTSC/PAL") and trace
the lead to the jumper it connects to.  Then find this jumper on your 
motherboard and cut it.  Install a wire to the lead coming from the
chip and another to a ground.  Put a switch between them.  When grounded 
it's NTSC and when open it's PAL.  Good luck.

As with anything hardware, I take no responsibility...

Well, excuse us for being beneath your vast and expansive understanding
of the theory of x-specs.  The people who responded to my original posting
all understood what I meant.  Is that not the primary function of
communication?  I don't correct people every time they end a sentence in
a preposition, because I still understand them.  I was aware of the
type of x-specs that you have described, but I also know that the little
"Plain 3-d glasses" of cardboard and plastic that are sitting on my desk
have the words "X-specs" printed on the side.

I am not trying to start a flame war here, I'm just saying that maybe you

abundant wisdom.
