I seem to remember that at some point early on, we spent some of our capital budget on buying another 16K bytes for the PDP-11.  As I recall, the deal was that the OS got 8K and users got 8K.  I also recall that that purchase was 20% of our capital budget for the year...

Doug, did I remember this correctly?

A self-imposed limit of 16K held in v1, and was quite fully utilized.
When the iernel was rewritten in C, the limit (perhaps larger by then)
influenced the C compiler. More than one optimization was stimulated
by the need to keep the kernel in bounds.
