'''Analog''' is a term used in computer-related discussions to describe the lowest ''conceptual'' level at which computer components can be examined. (Obviously, in actuality, all computers are 'analog' at their lowest level, since they are built out of electrical circuits.)
+
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 have focused on them.
  
−
As such, things such as [[voltage]]s, [[current]]s, [[resistor]]s and [[transistor]]s are the concepts used. Note particulary that voltages are not binary, but can take any value (one of the meanings of 'analog'); this is important in topics such as [[meta-stability]].
+
For more about me, see my [http://www.chiappa.net/~jnc home page].
  
−
The term is also used to name computing devices in which infinitely variable [[voltage]], etc, levels are used as data, instead of the limited discrete values used in [[digital]] computing devices.
+
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.

Revision as of 14:45, 21 March 2020

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.

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.
