Despite being marketed as a 'Pocket Computer', the TRS-80-PC2 was a giant; almost 12 inches in length and weighing nearly a pound. This size, however, allowed for very powerful equipment to be fit into this space. With a custom LH5801 8-Bit processor running at 1.3MHz and 1.85K of RAM (with an additional 8K available in expansion cards), with a better built in programming language, this machine was incredibly capable for its time.
All of these improvements imposed a high penalty - power consumption. The PC-2 requires 10X the power to operate than the PC-1. As a result, it requires 4 AA batteries as opposed to the tiny button-cell batteries of the PC-1. A noteable feature of the TRS-80-PC2 was its printer. Unlike the earlier TRS-80-PC1 which utilized a dot-matrix printer, this machine had a exciting 4-color plotter capable of printing both text and graphics. Additionally, the plotter could resize print text in up to 9 different sizes.
