TI Calculators Play Movies

ipapusha writes "TI Calculator enthusiasts rejoice. A few weeks ago, Dan Englender released a new flash application usb8x. Usb8x is a driver that interfaces with the On-the-Go USB port in the TI-84 Plus and TI-84 Plus Silver Edition. It is designed to be used by other programmers to create drivers for a variety of USB peripherals, including a keyboard and mouse. Already, ticalc.org's own Michael Vincent has interfaced his Lexar JumpDrive to play The Matrix's famous lobby scene. (mirror) ."

Been there, done that

I wrote a program years ago that would convert videos to a TI calculator assembly program. That didn't end up on Slashdot, but if you want to check it out (with screenshots):

Remove the space from the URL I guess.

Of course, USB is nice and all, but the video-on-calc thing has been done before. By me :)

For the record, the 84+ uses a dual-speed 6/15MHz Z80.

There is some truth to that --- however, a good calculator, that fits in your hand, and has all the calculator functions available as keypresses, can still be more efficient than your laptop+CAS..

from that page, a link to a new calc being developed:

eCos, running in 512KB SRAM and providing one month of battery life
Linux, running in 64MB of SDRAM and providing considerably more than a day of battery life
A day of battery life??

The 83+ Silver and 84+ Silver have 2MB of ROM, and 128 KB of RAM, all done via page swapping in a 64KB address space. To get technical, $0000 to $3999 are fixed on ROM page 0, two of the remaining 16KB chunks can be mapped to any of the RAM or ROM pages, and the last 16KB chunk can be mapped to any of the RAM pages (can't do ROM as this is where the stack is; hardware prevents it anyway). It *might* be possible to run linux, but it wouldn't be very practical unless you build USB Mass Storage drivers into it (and that would restrict it to the 84+ only). You know, that's a project idea...

Wikipedia to the rescue. The TI-89 had two hardware versions (three if you count the titantium). HW1 had a 10 MHz processor. HW2 and HW3 (titanium) have a 12 MHz processor. HW1 and HW2 appear identical, except they show a different version number on the about screen ([F1]+[A]).
