The latest TI-84 Plus gives an unmatched contrast
of the pixels and a crystal clear view.

The screen of the TI-84 Plus Silver Edition is
identical, only the colour of the housing changed.

The TI-89 Titanium sports much more pixels in the rows
and columns compared to the TI-84 Plus series.

The new TI-84 Plus integrated not only the 
Z-80 microprocessor but also the RAM and 
USB logic into an ASIC. The LCD-driver is 
now integrated on the main PCB.

The new TI-84 Plus Silver Edition makes use of an
identical PCB like its smaller sibbling TI-84 Plus but
sports a FlashROM of 2M Bytes instead the 1M Byte
chip.

The new TI-89 Titanium is centered around an ASIC, too.
Nevertheless is the architecture totally different, one of
the chips on the printed circuit board is a standard
MC68EC000 32-bit microcomputer.
