A couple of years ago I first posted about the Cody Computer, a 65C02 and Propeller-based system inspired by the Commodore 8-bit family. I've finally gotten things finalized enough to put up all the design files and source code for the project in time for Christmas. Everything is released under the ...

January update:

I've gotten Cody Basic (the Tiny Basic-like dialect I mentioned above) more or less completely finished; along with a few kernel-like routines for things like keyboard scanning and SPI operations, it clocks in around 6 kilobytes in size.

Along with the typical Tiny Basic commands ...

@cbmeeks:
Very good job!

How are you handling the voltage differences between the Prop and the CPU? Are you running the CPU at 3v3?
Any schematics?
Thanks! Your inference that I'm running at 3.3 volts was correct; considering the entire machine is running at 1 MHz, the remaining ICs on the ...

I thought I'd post an update regarding progress through August and September.

The keyboard is coming along rather nicely. Instead of the tact switch "keyboard" in the previous post, I now have a keyboard using Cherry MX blues with 3D-printed keycaps. The legends are actually printed into the ...

I've been working on the Cody Computer off and on for a couple of years in one way or another but finally decided to post some build-in-progress news and pictures; there are a couple of postings I've made on the site regarding particular 65C02-related questions but nothing in detail regarding the ...

Does anyone have any experience (or information) as to whether the W65C21S is suitable for operation in 3.3v circuits (with suitable downrating of the clock frequency)? My confusion stems from the following:


The data sheet initially specifies a 5V supply with a tolerance of plus or minus 10 ...

Thanks so much for all the replies, not to mention the warm welcome!

I'm going to take the weekend and digest a lot of this information to try and decide if I want to go with a full W65C265S-based system for my first foray into this realm or stick with a more traditional 6502 circuit since it's my ...

Hello! I'm a long-time electronics hobbyist (started out as a child, built my first single-board computer during junior high school around Robert Grossblatt's "The 8088 Project Book" with my father trying to help me debug it using his two-channel oscilloscope) who's been wanting to build a 6502 ...
