  • Las Computadoras de Costa Rica
    This year I began giving classes in computer programming as well. I use the Sinclair simply because it is cheap. The economy is on an even keel, but it is still not moving very fast.

    On October 22, 1983, the Boston Computer Society’s Sinclair-Timex User Group celebrated their Second Anniversary at the Boston Park Plaza Hotel.
