Continued from 16-bit Processor Build - Design Work, part 1... Currently-planned Instructions My current plan is to have approximately 40...

I have started the hardware build of my 16-bit processor. In this running post, I will share progress updates and lessons learned as I...

As I have my VHDL-based prototype of my 16-bit processor running, I am now starting the design work on an actual hardware implementation....

I have started building an assembler for my 16-bit processor (prototyping in VHDL, later will implement in hardware). Initial assembler...

I am hoping to learn more about processors by building a 16-bit processor. I previously built an 8-bit processor based on Ben Eater's...

I have previously built an 8-bit processor (my 8-bit) using Ben Eater's video series. Since then, I have been spending time on 6502 and...

To practice my 65816 assembly, and refresh myself on Ben's 8-bit CPU... And an emulator running inside an emulator... 🙂 On my Windows...

In January of this year, I decided to try to build a new system based on the 65816 processor. It has now been almost five months, and I...

To enable more verbose debug logging at runtime, I have added a higher-resolution LCD. Communication from the 65816 is handled with SPI....

My sound card is now substantially complete, and I can continue working on system assembly code to better utilize it. I have the sound...

I was getting a bit tired of the previous song I had been using for my sound card testing. 1SMHARRIS suggested a song to try out next. In...

I now have the onboard SD Card (SPI for communication) working on my sound card. I ended up going without the hardware shift registers...

As I've been making some good progress on my sound card for my 65816 system (see /audio), I thought it would be good to start building...

Continued from Sound Card 2.0 PCB Build (rehsdonline.com)... I now have playback working from the media ROM on the sound card....

Previously, I designed a PCB for my 6502, PS/2 keyboard, and VGA. The design is based on Ben Eater's video series. The only addition I...

I have received several inquiries from others wondering about building their own version of my 65816 motherboard. If you're interested in...

Continuing with my 65816 Emulator series, my 65816 PC build is now to the point where an emulator for my sound card would be helpful. I...

In this running post, I will share the buildout of my sound card for my 65816 PC. Having the PCB in hand, I can say this will be the...
