That's a shameful way to go

I'll try not to take that personally, don't know really how though hehe
Both worlds have their advantages, assembly has that warm fuzzy feeling of being really cool, understanding your poo and good craftsmanship
Web development has that really warm fuzzy feeling of design and beauty, and good craftsmanship

I do feel that my assembly coding is't in any way "wasted", it tought me lots of stuff I have use of even as i hack away at JavaScript and CSS

Thank you very much! I'm using the tutuorial right how and I find it extremely helpful.

Again, Thank you!

These look great - thank you so much for producing and publishing them.

For what it's worth PDF is best (IMHO). Just need to print them off when no-one is looking at work!

They read well and make so much sense.

Cheers,
Simon

Hello,
Just wondering if this is still downloadable as a RTF or doc or acsii!?

Thanks

These plus many more by other people are on the Wiki - http://www.atari-forum.com/wiki/index.p ... _tutorials

Hum, I need time to finish this part with "Tutorials from Féroce Lapin".

viking272 · Post by **viking272** » Wed Oct 29, 2008 10:42 pm

The Wiki is great. Lots of good information - and if others can add to this that is awesome!

Is anyone able to recommend some tutorials on 608060 coding and what tools/compilers are available?
I have had a quick scan through Google and DHS site but nothing jumps out?

Cheers

I see that you have also added one of my document on UltraSatan

which is fine. But you should probably replace with the new version I just posted here http://www.atari-forum.com/viewtopic.php?f=15&t=18027

Awesome documents!

I'll upload the ones you said. Thanks a lot. Most difficult part of having an FTP Server, is to be up-to-date

Does it works on teh Falcon? I tried the first part of the tutorial where you change the background screen to red colour, and on the STE works perfect but on the Falcon do not happens anything. Thanks.

Post by **simonsunnyboy** » Sat Dec 12, 2009 5:50 pm

Well, it basically works. The Falcon just requires some Falcon specific hardware register dabbling to switch the video hardware into a more ST(e) compatible mode.

For a start, try using the ST-compatible resolutions from the Desktop.

It worked! ("of course it worked", you're thinking

). Thanks a lot

I'd just like to thank perihelion for doing this (though his account seems to be gone ? )

I've printed the guide out so I can scribble all over it and am determined to learn some asm this year

I've got to the 'fill screen with colours and fade it' part and have managed to work out how to stick some text on the screen too and fade that (though I'd like to keep the text and fade the background, but thats an 'exercise for the reader')

My fault - bit too enthusiastic when deleting inactive accounts

perhaps you could restore it from a backup?

man, I've just seen that he was killed a few years ago,

I didn't realise.

Yep, which was why I felt so gutted when I removed his account along with 200+ inactive users/spammers at the same time. I've asked Silver Surfer a while back to see if he could recover Perihelion's account - must remind him again.

PaulB · Post by **PaulB** » Thu Jun 03, 2010 1:22 pm

Don't worry about it, Mug. These things happen, especially when trying to deal with the ever increasing amount of spammers on the web. At least his name is still there, that's the main thing.

I saw this post as new to me. Haven't been very active here for a while. I read from the top of this page downwards and thought 'poor perihelion' on the posts that he himself made, when I remembered what happened. Such a shame, such a waste of talent and a good person. RIP perihelion.

I've just started in on Perihelion's (very sad to read what happened) tutorials using Devpac-3 and have some fundamental questions for getting up and running with this software.

I'm only on tutorial 2 presently and have entered this code:

clr.l - (a7) clear stack
move.w #32,- (a7) prepare for super mode
trap #1 call gemdos
addq.l #6,a7 clear up stack
move.l d0,old_stack backup old stack pointer
move.w #$700,$ffff8240 red background color
move.l old_stack, - (a7) restore old stack pointer
move.w #32,- (a7) back to user mode
trap #1 call gemdos
addq.l #6,a7 clear stack
clr.l - (a7) clean exit
trap #1 call gemdos
old_stack dc.l 0

When I attempt to assemble the demonstration code, Devpac gives me:

12 errors found
14 lines assembled into 4 bytes, Atari executable position-independent code

Then when trying to execute, "No program available"

I'm using Steem 3.2 with xp ... I have my hardware STs near by but would really like to do this via emulator first especially considering the practicality of that.

Would appreciate some guidance very much!

Cheers ~
