It’s done!

The TwitALU in it's entirety.

The TwitALU in all its glory..

It’s been a long time since we’ve posted but the TwitALU is finished! It has already been shown off at the University of Bristol Open Day and the DigiMakers event at At-Bristol (review).

After the break are a few videos and photos of the TwitALU in action!

Introductions and the 6502 ALU

Before I tell you about the juicy guts of the 6502 microprocessor, let me introduce myself and tell you a bit about the people behind the project.

My name is Jaimesh Mistry and I am a fourth year Electronics and Communications Engineering student, studying at the University of Bristol. I’ve been ripping apart electronics and changing the way they work ever since I got my first RC car and went exploring in my dad’s crazy toolbox. These days I’m building all sorts of wacky projects with the skills I’ve gained at university – fromĀ  autonomous robots to central heating systems that you can control from your smart phone. Hacking consumer tech is one of my passions, so a project like this where we mix a range of technologies from a range of eras in computing is right up my street.

Jeremy Dalton completes our duo and is also an Electronic and Electrical engineer in training at the University of Bristol. Like me, he is into all sorts of software and hardware hacking, has ‘tweaked’ many a working thing until it stops working and we’ve successfully collaborated on a good few projects in the past. However, one of his growing passions is in dirty great power electronics and motor drives, which recently landed him on an episode of Channel 5’s Motor Morphers where he helped convert a two-tonne milk float into a rubber burning dragster!

Anyway, enough about us. As promised, I’ll walk you through the MOS Technology 6502, why we chose it over other classic processors and our simplified design for implementation in 7400/relay logic. Continue reading
