- How ?
Like all modern processors the Megaprocessor is built from
transistors. It's just that instead of using teeny-weeny ones
integrated on a silicon chip it uses discrete individual ones
like those below. Thousands of them. And loads of LEDs.
- Why ? - short
answer : Because I want to.
- Why ? - long
answer : Computers are quite opaque, looking at them
it's impossible to see how they work. What I would like to do
is get inside and see what's going on. Trouble is we
can't shrink down small enough to walk inside a silicon chip.
But we can go the other way; we can build the thing big enough
that we can walk inside it. Not only that we can also put LEDs
on everything so we can actually SEE the data moving and the
logic happening. It's going to be great.
- When ? I was shooting for the end of 2014.
But that was fantasy. It's turned out to be quite a project,
things seem to have got a tad out of hand.
Easter 2015. Summer
2015 (and this time I mean it) Easter 2016 (and now I
really really mean it). If you want an update on where I'm up
to there's a diary of sorts here. (Last update 23 May 2016)
- So how big will it be ?
Well an 8-bit adder is about a foot long (I use five of
- And the whole thing ?
Well according to my current plans, if I ever finish the
soldering, and if I can ever find a room big enough for the
Megaprocessor to properly unfurl its wings, then it will look
roughly like this:
As of 30th January 2016 we have seven frames (which is enough to
build a working system !) and we're into test and integration.
