Replying to myself :( The mode was called PC relative addressing, and resulted in smaller, faster code on the 68000, but things had to be written in 32k chunks

Replying to myself :( The mode was called PC relative addressing, and resulted in smaller, faster code on the 68000, but things had to be written in 32k chunks. I seem to recall that it was required for the original Macintosh before they wrote a proper program loader. Anyhow, some of Knuth's code (hiss BDD package at least) has hacks to reduce the size of pointers.
