Who am I? CPUID on the PDP-8
Portable software must adapt to peculiarities of the target platforms.
Even variations within a "compatible" family of computers may require
specific code. But how does a program identify which machine is
executing it? In this presentation we will dissect, line by line, a
subroutine written by the late Charles Lasner (CJL) as part of the
Kermit implementation for the PDP-8 family of computers. The subroutine,
"MACHINE", is capable of identifying all DEC PDP-8 models. Some
familiarity with programming will benefit the listener, but the
presentation includes the basics of PDP-8 assembly and the level should
be approachable to most.
Pontus Pihlgren (Update)

The lecture is free and open to everyone.
