There’s a new fun device in my lab today. The Clockwork Pi PicoCalc, a retro-inspired handheld that blends nostalgia with modern DIY flair. Powered by a Raspberry Pi Pico, it’s perfect for tinkering.

Out of the box is boots directly to a version of BASIC called PicoMite. It’s a version of MMBasic that’s been optimized for the PicoCalc. It’s a great way to get started with programming on the PicoCalc. Other languages like Python/C/C++ are also supported, but I will primarily be using BASIC on it.

My son, now 25, was a McNuggets fan. Can you blame him? They’re delicious. He’s always been into numbers and puzzles, so I introduced him to the McNuggets problem when he was about 10.

This classic puzzle was a fun way to keep him occupied and teach him programming. The problem is simple: McDonald’s used to sell Chicken McNuggets in 6, 9, and 20 packs. What is the largest number of McNuggets you cannot buy using these package sizes?

Back to the basics with basic

Let’s say for a moment that we’ve got an ordered list of numbers.

1,3,5,7,9,11,13,15,17,19,21,23,25

There are 13 values here and we want to check if the number 25 is in this list.

One way to do this would be to loop over each element in the list and check to see if it matches what we’re looking for.

In BASIC, we’d do something like

I was recently on a video call with a friend, throwing around some ideas for a new product. I mentioned adding large signed numbers in assembly and using two’s complement. He asked me what two’s complement was. I was a little surprised that he didn’t know. He’s been a Java programmer for more than 30 years. Java and Python programmers (and others like gasp Commodore / MicroSoft BASIC) don’t have a native unsigned integer type. The language takes care of the details for you.

Rockwell International was a powerhouse of the 1970s and 80s.

The Rockwell AIM 65 computer, also known as the Advanced Interactive Microcomputer 65, is an early microcomputer produced by Rockwell International in the late 1970s. It was essentially a development system, intended primarily for engineers, educators, and hobbyists, and was named for its built-in alphanumeric keyboard and LED display.

The AIM 65 was built around the 6502 microprocessor, the same chip used in popular systems like the Apple II, Commodore PET, and Atari 2600. The AIM 65 was designed as a single-board computer, with the processor, memory, input, and output all integrated into one circuit board.
