Hi there.

Anybody would be interested in making a small BASIC demo for unexpanded ZX81?

Probably it would be something in style of this compo http://zx81.republika.pl/ I made in 2007.
So it's really time for something new.

And maybe some coding this time?

I'm a very crap coder, so my "demo" is shitty.
But I still love coding on ZX81, so I made one too.

At the moment, for now, we have 2 entries.
http://yerzmyey.republika.pl/1K.P
http://yerzmyey.republika.pl/piss1k.p

I put them on the Net to show You what we are talking about.

The demo must work on unexpanded ZX81 and should be written in BASIC.
Would be nice if the prog start itself (but if it's a problem then it doesn't have to).

You can submit more then one demo.
But no multiloading. At least this time.
So - no many parts loading one by one. Only 'one-part' demo.

Send Your work in *.p files (well, can be also TZX) into my e'mail address: yerzmyey AT interia.pl

The deadline might be 20 Decebmer 2009.

OK?????????????

Greetz,
Yerz

Gasman reported that the http://zx81.republika.pl/ was hacked.

***NOW EVERYTHING'S OK***

You can safely enter the site.
That's the comparison then. I think the compo site will look similar to this one, supposedly on the sam address (but with menu).

So - I'm waiting for Your ZX81 1Kb demos on address
yerzmyey AT interia.pl

How can anything compare to your work, Yerz?!?!!

[yerzmyey]

Mine is crap but Johny's work is incredible indeed, hahaha.

Well, it was my first attempt to make a 1Kb prog for 1Kb machine.
I didn't realized about a half of problems related with it.

Moreover I decided this year make a coding compo instead of GFX.
The only condition - BASIC.

It may be a mistake from my side but only in this case works will be on come comparable level, if You know what I mean.

Anyway, I hope people write some 1K demo progs!!!!!!!!!!!!!!!!

I want to participate, but I have to be honest. It's going to be a ZX Spectrum simple demo and people are going to try and help me convert it to the ZX81. I don't know ZX81 BASIC. I tried to do something yesterday, but couldn't even get the symbols and keywords right. But I'll have something to show. That's a promise!

[yerzmyey]

OK, it would be cool. Thx.

Btw, the extended mode in ZX81 is really pretty strange because You have to press SHIFT+ENTER.

Reminder to everybody: pls make some short BASIC demo working on ZX81 1Kb and send it to me on
yerzmyey AT interia.pl

!!!

You surely forgot how cool ZX81 coding is!!

The best 1K demo I have ever seen is Wilf Rigter's HIRES demo described here:

http://www.zx81.nl/dload/utils/wrx1k12.txt

And the program itself is there:

Doesn't work on emul (I'm at wotk, at the moment). I will check it out in the evening.
Does it require any hardware midifications?

Anyway it's not i BASIC, so cannot "compete".
This time at least.

AKAIK: works with some emuls

No

This time at least.

The main work (drawing circles) is done by a BASIC program. Only some"little" tools (HIRES-driver, HIRES-plot-Function) is done in machine code.

Hehe, still machine code used. ; )
Although if the machine code is written in basic interpreter, then it's still basic for me. So it could be - if it was new.
But it was released in 1996, hehe.


Btw - more than one work from an author is allowed!!!!


Code, people - do code!!!
