Mathatron & other stuff

Hello out there in classic computer land, I'm new to the list and wanted to introduce myself and my Web pages to the rest of ya'll. My name is Alex Knight and my Web page, the Calculator History and Technology Archive, is located at: http://aknight.home.mindspring.com/calc.htm My interest is primarily in early-model electronic calculators, but there are some crossover machines that seem to fit the bill as classic computers, and in my searching for old calculators I sometimes turn up some interesting old computer stuff. One of the more interesting machines that I have written an article about for my Web site is called a Mathatron, which was advertised as a desktop calculator/computer and sold as early as 1964. The Mathatron is a very large and heavy (24" x 24", 80 lbs) machine, but it will fit on top of a sturdy desk. I believe it to be the first programmable calculator, and some other people I've talked to consider it to be the first desktop computer (because of it's programmability, available peripherals, etc.). So ya'll take a look and let me know if you have any additional info. on this unit that I may be able to add to my article. Another "crossover" machine that I have a little info (mainly pictures) of is the HP 9830, called a calculator but in fact a computer with BASIC. Also on my Web site is a list of things that I'm looking for and things I have for trading, as I find classic computer items that I put on the trading block I'll send a message to the list to let ya'll know. Have fun, Alex Knight Hillsborough, NC
