Radio Shack TRS-80 PC-2 Pocket Computer and Printer Prev Stop Play Next Introduced: January 1982 Price: US $280 Weight: 400g / 14 oz CPU: Sharp LH5801 @ 1.3Mhz Memory: ~2K RAM, ~10K max. Display: 26 character LCD display Power: 4 "AA" batteries Storage: Optional audio cassette Peripherals: Printer (included) OS: BASIC in ROM Radio Shack's second "pocket computer" is no pocket computer - it is much too large and heavy. Like the smaller and lighter original PC-1, the PC-2 was also designed by Sharp, who released their own version, the PC-1500.  With physical dimension which seem like a disadvantage, the software and additional features make up for it.  The PC-2 has a faster and more powerful CPU, a better BASIC programming language (built-in), and expansion capabilities beyond those of the PC-1.  The RAM/ROM module slot on the back also adds greatly to its size. Application modules can be installed here for instant access.  These include: Games Statistics Personal Finance Business Finance Investment Analysis Chemistry Math and more. Alternately, addition memory (RAM) can be installed for memory-intensive applications. Radio Shack sold 4K and 8K RAM modules for the PC-2.  The PC-2 has a exciting 4-color plotter capable of printing both text and graphics.  The plotter attachment also provides program loading, data storage and retrieval through a cassette interface.  The PC, interface, and power adapter all appear in perfect condition and are believed working, however this item is being sold as-is.  I do not have the time or expertise to operate it or take it apart.  The printer/plotter shows a printed test that was performed before I obtained this unit for my collection. Payment by PayPal is expected within 3 days of auction close. Shipping and handling charges are clearly noted in each of my listings. I am happy to combine shipping if multiple auctions are won (with few exceptions, you will pay only the shipping and handling of the largest item you win). I ship only to verified addresses within the United States (sorry Canada, I love you, but shipping rates are outrageous and the Customs paperwork is a pain). All items are sold as-is, with no warranty or guarantee, unless specifically noted in the description. I do my darnedest to describe my listings accurately. Feel free to ask any questions before you bid.
