Brilliant stuff, I love this combination of era's!
I have a 100 year old Drummond Round-Bed metalworking lathe that I'm planning on converting to CNC, that'sll be a nice mix of technologies!
I've only managed to datalog signals in my central heating boiler so far using my Pi..
Bearing in mind that all signals in my boiler are 240V mains, I had to build an opto-isolated interface circuit to keep the pi safe! a nice man on teh RaspberryPi forum wrote the code for me to log the time upon a change of state of any of the GPIO, and to record the states of all GPIO at that time.
End result, we're having a new boiler installed tomorrow at
great cost, but it was worth a shot, and an interesting little Pi project!

This Pi is going to be relegated to media playing use behind our TV, but i'll be buying a model B Mk2 to use for fun!
