Following Ben Eater’s 6502 project – parts 5 & 6

Back in the first half of February, Ben Eater added parts 5 and 6 of his YouTube series on building a 6502-based homebrew computer. The enhancements he made gave the computer something it has been sorely lacking – memory. And the reason the computer needed memory was so it could have a stack. Up to that point, the code had… Read more »

Zolatron 64 6502 homebrew computer – new address mapping and decoding

Although it is possibly the slowest computer development programme in history, my Zolatron 64 6502-based homebrew design has made some progress. And this is largely due to the fine folks over at the 6502.org forum. Specifically, I have made changes to how I’m mapping the 64KB address space and the decoding I’m using to do that. I’ve been following along… Read more »

Building a PC: RAM – Corsair Vengeance RGB

First steps The case – Corsair Carbide SPEC-06 PSU – EVGA 1000GQ Gold The motherboard – Asus Prime X470-Pro RAM – Corsair Vengeance RGB GPU – PNY GeForce GTX 1660 Ti Putting it all together Wrapping up This should be quick. The Asus Prime X470-Pro motherboard I’d settled on needs DDR4 RAM. The board supports 3600MHz memory. I’ve heard good… Read more »

Zolatron 6502 computer: decoding the RAM more reliably

In my earlier post on address decoding logic, I mapped out a fairly simple way of dividing up the 64k address space for my 6502-based retro computer. But maybe it was too simple. There is one slight complication – easily fixed, but which will require the introduction of another chip. And the reason for this is something lacking in memory…. Read more »
