I'm working with what I have... I have a 65816 computer, and I want a USB mouse. I have a 6502 computer with USB mouse support. I have...

As I have now found some nice stability with my 65816 system running at 14.16 MHz, I thought I would come back to bus resistors and see...

My first attempt at sprite transparency... and it's pretty rough. I updated my image conversion application to support converting images...

I am working on the breadboard build of my Sound Card 2.0. I'll use this post for updates on my progress. I figure the breadboard build...

To facilitate developing new circuits for my 65816 system, I have designed an extension for my bus, leveraging the ISA physical...

With my 65816 system up and running, I can now start working on add-in cards. A simple one to start: an LCD. I designed the PCB to be...

Now that I have my 65816 motherboard working, I would like to improve speeds. The symptom that I see (and would like to improve) is that...

I'm getting close to having my 65816 PC updated with rev 1.1 PCBs (for the motherboard and video memory card). I have a plan for a USB...

Continued from VGA for 65816: First Run at Moving Content... My first animated sprite (32x32) on my 65816+VGA system! While the video...

So much room for improvement, but it's a start to moving content... The 65816 is running at 5 MHz for this test.

As I am working on my VGA card build, the next step for me is to improve the accuracy of the color output -- well, as accurate as I can...

I have started the assembly of my VGA card for my 65816 PC. In this running post, I will share my updates as I work through assembly,...

(Latest video posted at the bottom.) While I'm waiting for my 65816 system PCBs to come in, I thought I would see how far I can get with...

I will update this post as I work on my 65816 PC and identify mistakes in my 65816-related PCBs, so check back to see how they all pile...

I have the initial layout and routing working for my 65816 motherboard, video card (including memory daughter boards), and prototyping...

Continued from 65816: Driving VGA Through Dual-port SRAM... I made some progress today on my 65816 with VGA 2.0. Learned a bit about...

At the end of January, I posted A Start to Video Output for My 65816, where I built a stackable dual-port SRAM PCB that could later be...

(Continued from 65816: VIA1 Working...) I updated my 65816 clock to 8 MHz. It seems to be taking it OK. :) 16 MHz oscillator into 7474...

Continued from VGA 2.0: First fire-up of the basic circuit... Here's my obligatory finch post: I can probably work on the resistor values...

I have fired up the basic circuit for my VGA 2.0 (320x240x1byte). I can't say it's pretty, but it's at least outputting something. Now,...
