The purpose of the Smalltalk project is to provide computer support for the creative spirit in everyone. Our work flows from a vision that includes a creative individual and the best computing hardware available.

Remembering the LAN

I started programming in the 1990s living above my parent's medical practice. We had 15 PCs for the business, and one for me. The standard OS was MS-DOS.

ThinkPad 560E

I’ve been idly looking for one of the mid-90s ThinkPads known to have perfect OpenStep/Rhapsody support for years as a fun collector piece, but been unwilling to pay eBay prices. The other week I scored a pristine IBM ThinkPad 560E for $20 in a Shopgoodwill auction, below is notes on getting it up and running, plus…

Roman Finger Counting

I recently wrote a final paper on the history of written numerals. In the process, I discovered this fascinating tidbit that didn’t really fit in my paper, but I wanted to put it somewhere. So I’m writing about it here.

The CPUs of Spacecraft Computers in Space

Many CPUs have been used in space craft, space stations and other such probes. Such CPUs must be highly reliable, and very durable. The temperatures in space, even with heaters, can vary widely. The radiation that a system is exposed too can be immense. So when designing one of these systems designers don't always use…
