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 [[instruction]]s were a revelation when they first appeared), so I started out by focusing 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]]. (All of that was in the context of my work on the [[Internet]] - and, yes, it '''''is''''' spelled with a 'I'.)

For more about me, see my [http://www.chiappa.net/~jnc home page]. I joined the project here at the end of November, 2015‎‎, and have been working on it ever since. [https://gunkies.org/w/index.php?title=RK11_disk_controller&oldid=11294 This] seems to have been [https://gunkies.org/w/index.php?title=Special:Contributions/Jnc&dir=prev&limit=500&target=Jnc my first edit].

Me

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 started out by focusing 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. (All of that was in the context of my work on the Internet - and, yes, it is spelled with a 'I'.)

For more about me, see my home page. I joined the project here at the end of November, 2015‎‎, and have been working on it ever since. This seems to have been my first edit.

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 alum dot mit dot edu).
