Testing the Ruby 6502 After making it on breadboard, I was already relatively confident that it would work on stripboard and my initial testing went well. I could access the shared RAM from the ATmega, write test patterns into it, … Continue reading

How does it work? The 6502 (or W65C02S in our case) is really designed to have some ROM (or modern flash, etc.) to enable it to boot. At power on or reset, it reads an address out of a fixed … Continue reading
Where next? I had a barely working 6502 prototype system on my workbench. It was a little unstable and didn’t like being moved, but it did work and demonstrated to me that the concept was viable. Initially I didn’t know … Continue reading
I’m asked many times why wiringPi has its own pin numbering scheme for the Raspberry Pi, rather than use the native hardware pin numbering (which is can also use, along with the physical pin numbers).. The answers are simple… Firstly… … Continue reading
Just to show you that I don’t just do Raspberry Pi stuff… 4D system have produced a shield that allows you to connect the Intelligent displays up to the Arduinos serial port, so I’ve ported the Raspberry Pi VisiGeni driver … Continue reading
Just a note to say that I’ve updated my WiringPi libraries. It now should work fine with C++ programs and there is an added function (and flag to the gpio program) to switch fron the WiringPi Arudino-like pin numbering to … Continue reading
To use the GPIO pins on the Raspberry Pi, I have written my own access library and modeled it on the Arduino Wiring system. It started life as the means to allow my BASIC to access the GPIO pins, but … Continue reading
Decided to produce a standard Arduino Sketch to implement DRC, as well as my original version which runs under DROSS. Admittedly, DROSS is a bit overkill for this little project, and most people will probably be more familiar with the … Continue reading
Getting there slowly and I’ve now put up some data on the Drogon Remote Control pages. I think I need to investigate some photos and probably video links too – as I’m sure nothing beats a video these days. Also … Continue reading
