Reverse Engineering the 6502 - the movie
Sunday, 09 January 2011

Back in September we ran a news item about the reverse engineering of the 6502 microprocessor using acid, graphics and JavaScript. Now we have a video update on the whole wonderful, but slightly crazy, project.

 

OK I admit it isn't actually a movie but is instead an hour-long talk broken down into 10 minute segments. The subject matter is how to reverse engineer a 6502 microprocessor using acid, graphics and transistor level simulation. We covered the basic idea back in September 2010 (see Transistor level 6502 simulation)   and the video is basically a presentation of the same ideas with an update.

In case you missed the earlier news item, what happens is that the group take the top off a chip, eat away at it with acid and then photograph the layers that are revealed. From the photographs they then create a drawing that is essentially a map of the chip and from this they can identify transistors, diodes, resistors, capacitors and interconnections. The graphic serves as the basic input to a simulator written in JavaScript which can take programs and run them as if it was the native hardware - only slower of course.

The video presentations are fairly technical and go into a lot of detail about the 6502 and assembly language but if you are a hardware oriented sort of guy its a lot of fun.

Microsoft has formed the .NET Foundation with the idea that the best future for the technology is open source. Is this a positive or a negative in the life of .NET?

Google's tradition of taking April Fool's Day seriously is so well known that wait wait expectantly to see what it will come up with each year. In particular what is there for developers?
