PDP-11: perhaps the most sensible assembly language of its day (and for quite some time afterward). I wrote 10's (100's?) of thousands of lines of PDP-11 assembly, including (privileged) code that used the APRs like an 808= 6 uses segment registers. ~ Bob Ammerman RAm Systems > -----Original Message----- > From: piclist-bounces@mit.edu [mailto:piclist-bounces@mit.edu] On Behalf Of > BOB > Sent: Monday, March 02, 2015 8:56 PM > To: Microcontroller discussion list - Public. > Subject: Re: [OT] 50 years ago... >=20 > Ah the VIC 20.
