User:Jnc
Although I have a wide interest in older computers, I worked with PDP-11's extremely 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. I also worked a lot on early UNIX (whose bang/buck ratio has never been surpassed, and almost certainly never will), back when it only ran on PDP-11's, before it was portable.
For more about me, see my home page.
Also, I'm an admin here on the CHWiki, so if there are any admin-type tasks you need doing (e.g. deleting a page with a typo in the name; merging edit histories; etc) just drop me a line (jnc at mit dot edu).
