10 Facts About the Commodore 64 Ultimate

Last month, I wrote about Commodore coming under new ownership with its new CEO, Christian Simpson (a.k.a. Peri Fractic), in Will We See a Commodore 64-Bit? While I have no idea if we'll see any 64-bit Commodore products any time soon, what we do know is Commodore has started pre-orders of its new Commodore 64 Ultimate computer. This new computer is intended to bring the much beloved Commodore 64 of the 1980's into the hands of those who grew up with the Commodore 64 as well as those that maybe have never even heard of Commodore. The revised C64 Ultimate…

Will We See a Commodore 64-Bit?

My first computer was a Commodore VIC-20. Having quickly outgrown the 3,583 usable bytes of RAM on the VIC-20, the Commodore 64, with 39,811 bytes free, became my second computer. Many late-night hours of my childhood was consumed pushing the limits of the BASIC language, and some assembly code, on these two marvels of computing technology. I loved to write games on these machines and my younger sister loved testing them out for me. I can easily state that Commodore shaped my career trajectory from a young age and I owe a lot of what I've accomplished over the years…

15 Quick Bits About the Commodore SX-64

It's time for the next installment of "15 Quick Bits About..." In this set of Quick Bits, we'll take a look at 15 facts about the Commodore SX-64. While I've owned several Commodore 64's (and VIC-20's) over the years, I've never owned an SX-64. If I ever come across one for a reasonable price, I'll no doubt pick one up. However, not having what is essentially a portable Commodore 64 doesn't mean that I can't learn more about it (and share it here) in the meantime. So, let's take a look...

Commodore Minuteman 3 Calculator

MM3 FYI: This is an article I originally posted on another blog site that I have (tronics.life) before Bits && Bytes had been setup. While I do not remember Commodore calculators as a kid, my first computer was a Commodore VIC-20. I loved my VIC-20 but quickly outgrew it. Eventually, my parents got me a Commodore 64 for Christmas. The 38,911 bytes available on my C64 was more than 10 times(!) what I had at my disposal on my VIC-20, which topped the digital scales at 3,583 (usable) bytes. I loved my Commodores and I spent countless hours writing software…

Commodore VIC-20/64 Screen Codes

Recently, I decided to type in some short BASIC programs for my Commodore VIC-20. To be fair, I haven't written any code for the VIC-20 (or C64) in quite a few years. I quickly found myself hitting the wrong keys on the keyboard (e.g., @ instead of double quote, etc.). What I also quickly realized is just how many of the special screen control codes I had forgotten (almost all of them!). Screen Control Characters Screen control characters (not sure if this is the technical term or not) are a way of controlling cursor movement and text color on the…
