- I hate to say it - but back in the old PDP11 days they had overlays.
- And learned to like them.
-
- And we walked 50 miles to school, uphill, and we didn't have shoes then...
- 8-)
-
- There is some satisfaction in shoehorning the most functionality in to
- the smallest space. The amazing fact that a PDP11 could multitask
- with the same 64k of memory that ran CP/M was amazing to me.
-
- I grew up with PDP11's and love the fact that RT11 can run foreground
- and background tasks (up to 15 background tasks) in a machine with only
- 64kb of real memory is a fact that some people that haven't had to live
- with those restrictions don't understand.
-
- Unfortunately, you can't run X in that space, or NFS... Perhaps TCP/IP
- though...
