Computer History: geek stuff.
In the 1980s I wrote dozens of letters to companies asking for more information on their products. Some of them manufactured hardware or wrote software while others were vendors of other companies’ products. I kept all the materials they sent me, from catalogs of software to brochures for new products, in a stack which eventually grew to over a foot high with hundreds of sheets of paper. Recently while going through my archives I decided to scan the more interesting stuff and make it available online.
