Over the years, I’ve been on a silly quest to do 10PRINT on as many things as I can. They end up on X, here, or sometimes both.

The “famous” 10PRINT program on vintage computers was a delight for many in the 70s and 80s. It’s fun to port to other platforms and machines.

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.

I’ve been on the prowl for an HP-16c for quite some time to add to my rather large calculator collection. My daily driver for the last 25 years is an HP-32SII. Simple, rugged, reliable, and does everything I need it to do.
