The internal construction of the TI-83 Plus with a 
Z80 microprocessor, 32k Bytes RAM and 512k Bytes
Flash-ROM and a supporting ASIC on the main PCB.
The second PCB holds the LCD-driver circuit.

The enhanced TI-83 Plus Silver Edition raised the 
Flash ROM capacity to 2M Bytes and integrated
the Z80 microprocessor into the supporting ASIC.
Even the LCD-driver is somewhat. smaller
