Nine selected mages from a program generated with Claude to compute Mandlebrot and Julia Sets using Atkinson dithering, running on an Atari 800XL.
It's using 16 bit fixed-point math and takes about 35 seconds to generate each one of these images. It's taking advantage of the extra memory (compared to stock 800) in the 800XL to compute and store a 32K table of squares.

I saw this little game at an airport then I saw it at a truck stop so I got it. The Atari pixel pocket pro….Not terrible imo, it has 25 games i think from the 2600 era and is perfect to tinker with and kill time.

Oh, look! An 810!

8 bit atari games often play better, are more entertaining and look better than ST games…. i may be wrong, I often am

No sound from the speaker, no memo pad, basic cartridge inserted brings the same exact issue. Is there anything I could do? I’ve tried cleaning the board like 10 times with no result. And for the life of me, I can’t find any information on this issue so I’m asking Reddit! Any thoughts/input would be greatly appreciated 😊

I know I shouldn’t be preordering crap, but again I was acting under the assumption I would be charged until it shipped.

I was digging in the closet looking for something and ran across an intact XF551 sans the disk mech, but I have a spare original Mitsumi mech. I also have an old Teac 3.5/5.25 dual mech.

Should I...

A: Restore it to stock in all its beige glory?

B: Build a unique dual mech contraption?

I already have a functioning stock original 5.25" and a 3.5" unit I modded years ago.

No XFs will be harmed in this endeavor either way. 😁

Take my money!

Hi! We’d like to share *Taca Taca*, a game for Atari 8-bit systems inspired by classic table soccer.

This Atari version is simpler and more basic than the current version of the game, but it is fully developed and ready to play.

🎮 Atari 800 / 800XL and compatibles
⚽ Game inspired by classic table soccer
🕹️ Fully functional Atari 8-bit version
🇨🇱 Project developed in Chile

Currently available in Spanish only.

You can check it out and play it here:

I’d love to hear the Atari community's thoughts on the project.

Hi Everyone, I've been working on a Factorio style game for the original Atario 800 in my free time for a while now. The wonderful folks at AtariMania published it in their database and I wanted to share it here!

My goal was to fit as large of a tech tree as is possible in the 48k memory footprint of the original 800, mostly so I can play it on my 800 lol. Obviously I wasn't able to follow Factorio's tech tree identically, but I feel the gameplay has the same spirit. I managed to include three science packs, power mechanics, lots few logistical and manufacturing options, and more!

I included an xex for emulator/Fujinet compatibility and an atr file that can be written to disc if you so desire. Check it out if you're interested here, I hope you all enjoy it as much as I did building it!

No lag and great response . Already want another for the ST :) (edit : it is CX40, typo)

When I bought it, it was advertised as working, when I powered it on, the light would only come on about a second or so after flipping the switch. I am using a new electroware power supply instead of the original just in case it isn't safe to use. The disk drive, while appearing to work as the busy light goes off after power on as it should, goes back on when the computer is powered on.

Ciao redditors, voglio vendere su eBay un Atari 130XE con program recorder XC12 (registratore a cassette) entrambi testati e funzionanti in imballaggi originali completi di cartoni interni e polistiroli. Manca solo manuale originale che posso fornire in PDF.

Il tutto è accompagnato da alcune cassette di software vari e un joystick Suncom Tac-2.

Mi aiutate a stimare un prezzo onesto da inserire nell'annuncio?

Hi all, Another moddle aged ultra-nerd have massive Atari 800xl/1050 drive flashbacks via my R36H/RetroArch portable. One lf my MAIN nostalgia rushes besides playing 'Behind Jaggi Lines' is replaying the wild Synapse titles, my faves were:

Blue Max

Fort Apocalypse

The Encounter

Zeppelin

Rainbow Walker

Necromancer

Curious to know what people out there like. Also did they release titles when bought out by Broederbund?

But I guess Anchorage, Alaska is different. They had like 5 cartridges available! I have a working one, so. I didn't need one at that price. I:be never seen any of these in the wold. This was at the Anchorage Mall.
