There is an ongoing Indiegogo campaign called “X65GS 65816 Gaming Console“, see screenshot below. I – as the creator of the x65 project – do not support and do not endorse this campaign. In the campaign page they reused my… Continue Reading
I started a new debugger tool for my x65 project. Previously I created a dozen of single-purpose python scripts (running on a linux PC) that let me single-step the CPU, read CPU registers, dump memory and so on. The scripts… Continue Reading
I designed an enclosure box for the x65-SBC computer. For modelling I used Siemens Solid Edge 2024 CAD software, of which I have the Employee Edition. (I think it is just similar to the free Community Edition, but I did… Continue Reading
As mentioned in previous post, Matej asked me if Dreamtracker app is running on X65. I told him that yes, it should run, but better to test it first myself. I downloaded Dreamtracker in its current version V0.71, fired it up, and well, after a promising… Continue Reading
It’s Autumn again and I am revisiting my Project X65. My list of to-do tasks is endless and growing still 🙂 During the summer I have received a couple (2) of emails with comments: by Eric from France and by… Continue Reading
In the previous post I have mentioned that I am working on a port of the 32-bit Forth interpreter OF816 to my X65-SBC, an 8/16-bit retro computer that I am building. The software runs on the X65-SBC in the 65C816… Continue Reading
I am working on a port of the 32-bit FORTH interpreter OF816 for my X65-SBC computer with the 65C816 CPU. The OF816 was created by mgcaret and is available on github. I made a fork of the OF816 project and added a new branch for my work: x65-sbc. The… Continue Reading
Modern microcontrollers and microprocessors have built-in facilities for external debuggers to read/write registers, set breakpoints and generally fully control the CPU. This is one of the main usecases of the standard JTAG interface. The 6502 and 65816 CPUs were created… Continue Reading
In the last 2 months I have re-done my X65 double-decker computer into a Single Board Computer (SBC). The single-board version fixes some of the electrical problems I had on the first version and it has way better signal integrity… Continue Reading
In X65 the assembled CPU is either the 8-bit W65C02S or 16-bit W65C816S. The W65C816S is (partially) compatible with W65C02S. This page summarizes the differences from the low-level hardware point of view and in the case that the 65C816 is… Continue Reading
