Description


The first thing I noticed about this calculator is its size, it is big. It's like having a large plank on your desk. The good thing about that is that the keys have space and are of good quality and the display is large also. Four lines on a BASIC programmable device is really handy when writing large pieces of code.

The PC E-220 is programmable in both BASIC and Assembler. Programming in Assembler is done is a real build in Assember text editor, not via peek and poke instructions from BASIC.

The performance index puts the PC-E220 in the same category as the TI-92. Not bad at all considering the Sharp uses am 8-bit Z80 CPU @ 3 MHz and the TI-92 uses a 32-bit MC68000 @ 10 MHz processor! I might have to have a look at the settings of the TI, maybe something was slowing it down when I measured the performance index.

The PC E-220 is derived from the PC-E200.
