To be pedantic, it needs a 64K machine like the 1982 1200Xl or 1983 800XL so would not run on the (max w/o 3rd party mods) 48K Atari 800 from 1979. But yes, wow!

#12i'm not surprised. atari 800 was an exceptional machine. great work on the game though.
Yes, it had a lot of custom chips, and some of the same people (like Jay Miner) who worked on the Atari 800 design later were involved in designing the Amiga which likewise was based on custom chips.

#13The theme song linked at the bottom reminds me a lot of the System Shock 1 theme song

#14I was expecting a very basic raycaster, no textures etc. This is seriously impressive!
I was expecting it to need 128K!

IIRC (and I may not), I upgraded my 400 to 64k, and a "real" keyboard. But I think you could only address 48k of it at once or something hinky.

#16Slovak group GMG released a full featured FPS for 40+ year old computer (64kb of ram, 1.79Mhz 6502) Features: - raycaster engine running at 25 - 30 FPS - animated textures - lighting system - destroyable walls - automap - 3 enemy types - final boss game is fully playable in Altirra emulator video: https://www.youtube.com/watch?v=lRd3MucaRoU homepage: https://atari8.dev/final_assault discussion: https://atariage.com/f…
the FPS is really smooth - and the floating point (?!) calculations of the raycasting engine seem to be totally "on point" ?!?!
So I was curious about how the Atari 800 handled floating point calculations. As it turns out, Steve Wozniak helped develop the FP routines for the 6502.

#17Here's a video: https://www.youtube.com/watch?v=92K9wnk_4Cw Pretty interesting but it's a little hard to make out what's going on sometimes.
If you reduce the window to a very small size (or look at your monitor from a few meters away) then it's actually easier to see what's going on.

Yeah, you had ROM space (and potentially cartridge ROM space) eating into your 64K on all the models and had to bank-switch for anything more than 48K IIRC. With a BASIC cartridge in place you'd lose another 8K.
Also I don't recall any of the 400/800 3rd party upgrades being compatible - they used a different bank-switching mechanism - with the later XL/XE models.

Both the 400 and 800 had upgrades to 64K. The Atari 400 required some soldering and the 800 was simply a plug-in expansion.

Where did you get a real keyboard for the 400. I searched and searched and could not find one. I was so envious of the Timex / Sinclair folks who had a nice replacement.
