Angle math demo in PICO-8

November 1, 2021

We were discussing angles and coordinates in the #pico8 Discord and I whipped up this quick demo while we were chatting. It’s a neat demo, and super-neat how easy it was to put it together! The value of a tight feedback loop cannot be understated. gist.github.com/dansanderson/2…

PICO-8 fillp shortcuts

October 21, 2021

Tandy 1400 FD; NTS DreamWriter 200

August 22, 2021

Two quick ones today. First, a Tandy 1400 FD portable DOS machine with two 3-1/2” floppies and an LCD 80x25 screen. I don’t have a boot disk yet, freaks out after a few minutes, has a fishy odor. Looks cute though.

The HP 50g graphing calculator

June 9, 2021

In HP graphing calculators, between my beloved high school model (48GX) and the latest hotness (Prime) was the 50g. I thought I’d try to live without one but it actually has advantages over both of those models in programmability and data access (USB, SD card).

Compute!'s Gazette collection complete!

June 7, 2021

Collection complete! With this last acquisition I now have every print issue of Compute!’s Gazette magazine. Not counting the software special which for my purposes is nice to have but not essential. Gotta draw the line somewhere.

On PETs and rocks

June 7, 2021

The Commodore PET was named after the Pet Rock fad of 1976.

The original Pet Rock sold 1 mil units at $4 each in 1976.

The trademark holder reissued the Pet Rock in 2012. It is still available on Amazon for $20.

You can get an original issue vintage pet rock on eBay for $75.
