The TI 83 Silver Calculator Plus Edition is a newer version of the TI-83 Plus calculator, released in 2001. Its enhancements are 1.5 MiB of FLASH ROM, a dual-speed 6/15 MHz processor, 96 KiB of additional RAM, an improved link transfer hardware, a translucent silver case, and more applications preinstalled. It also includes a USB link cable in the box. It is almost completely compatible with the TI-83 Plus; the only problems that may arise are with programs (i.e. games) that may run too fast on the Silver Edition, or some programs which have problems with the link hardware. The key layout is the same.
In April 2004, the TI 83 Plus Silver Edition was replaced by the TI-84 Plus Silver Edition. They feature the same processor and the same amount of Flash ROM, but the TI-84 Plus Silver Edition features a built in USB port, clock, and changeable faceplates.
