Although I have a wide interest in older computers, I worked with [[PDP-11]]'s very extensively 'back in the day', and consider them perhaps the most elegant architecture ever devised (the power and flexibility they obtained with only 16-bit wide instructions were a revelation when they first appeared), so I have focused on them.

For more about me, see my [http://www.chiappa.net/~jnc home page].
