Ti-85 Megademo (Calculator demonstration)

This is a real-time demonstration coded in z80 assembly for the Ti-85 calculator. The Ti-85 was released in 1992, and has been discontinued for many years. This demo was released by group GL.Fusion and won first place at the 2007 Blockparty wild competition in Cleveland, Ohio. Music has been added during the video editing process, and is not actually run on the hardware.

@8monoxxx Yep, this is a cover by Dubmood&Zabutom of Joger's track

Pretty sweet; it's truly pushing the limits of the hardware. But when do I get to see a raycasting engine for my toaster?

[supportthe85]

sweet. my '94 CBL-85 ran something like that and i lost the link cable soon after. it was cool and it stayed with me.

@Nezbie I can only imagine.

@madmax2069 I tested with the idea for a bit, but quickly gave up. :-)

The effects were already relatively optimized, and I didn't think I had the energy or the technical chops to pull anything decent off given the limited resources.

@keoni29 Oh wow, i wish i knew before hand.

[keoni29]

@madmax2069 I know. I am working on a tracker for the TI83+/84+ :-) Check it out here omnimaga.org/index.php?topic=1­0550.msg191352#msg191352

@keoni29 It should be able to, the TI-83 and TI-84 can do it using its IO port this should be able to as well (it has the same IO port). It might not be as good as playing from a real sound chip and might suffer from some slowdowns seeing the Z80 CPU is probably being taxed enough as it is just from running the demo. i wouldn't mind seeing it done myself.

I wish the music was played on the hardware

The TI-85 couldn't have been released in 1992. During the 1st week of my freshman year of High School in 1991 I tricked my parents into believing my Geometry teacher required it for the course so they bought me one. It still works.

That's the sickest shit I've ever seen how many brat lawyers and doctors will use 84 pluses and never do Jack wit it

[yetihehe]

This version of music is MUCH better than the one on Fairlight demo!
