Why you no have full 128K RAM!? 

Though it probably just isn't there. It was presumably a money-saving maneuver, and it doesn't save money to keep the RAM there.

I think with certain hardware revisions or something, the fix is needed b/c of bad lcd drivers.

I remember there were pictures on datamath of some calc, showing the different ribbons going to the display but I can't find it now

EDIT: some interesting stuff at http://datamath.org/Graphing/TI-84PLUS_WM08_TL.htm#PCB , old data is old but still..

Calc84, you can call it my typo, but Art_of_camelot started it

The_mad_joob, the reason why yours doesn't require ALCDFIX is kind of funny, it's because your CPU is so dang slow. This affects the test in two ways, 1) it made the fps a lot slower than it should have been, purely because the CPU couldn't keep up, 2) when you are actually drawing stuff to the screen, the cpu is again slower and doesn't go faster than the LCD. Runer had the same thing happen to his calc.

Shmibs, could you find a way to get the results of that K calculator, really all we need is the port 15 value, which you can get with calcsys. I'm interested in K's because they are weird sometimes

thepenguin77, your information is a little out-of-date. I did some more research on the flash chips:

Known device IDs are

ID Device
23 512 K (4 megabit) (5.0 V) (e.g. Am29F400B)
B9 512 K (4 megabit) (3.0 V)
C4 2048 K (16 megabit) (e.g. S29AL016J)
DA 1024 K (8 megabit) (e.g. S29AL008J)Notice how the TI-83+'s chip was originally a 5.0 V chip, but is now a 3.0 V chip? TI moved to 3.0 V logic. This means that the calculator will safely operate down to voltages of 3.0 V. (In fact, the flash chip data sheet says the maximum voltage you can safely supply to the flash chip is 3.6 V.) If you supply more than 3.0 V, the voltage regulator just converts the extra voltage into heat. TI really ought to update the TI-83+ OS not to signal low battery until 3.5 V, and redesign the case to accept only 3 AAAs---think of all the millions of batteries being wasted! The same goes for the TI-83+SE. It also seems that the serial port now operates at 3 V instead of 5 V. The TI-84+/SE will also operate at 3.0 V (confirmed with an assembly program running with interrupts disabled), but the USB port might not work right.
