The PDP-11 is DEC's first and only 16-bit processor.
It was perfect right away
From DOS-11 V004A documentation:
Code:
If CTRL/C is typed immediately following the RETURN key, the Monitor will echo the ^C and hang
- a Monitor restart is required. A very slight hesitation (blink your eyes) after typing the RETURN key
is all that is necessary to circumvent this problem.
No, turning it off and on was not the FIRST way to solve problems on computers. The first was - blink-blink.

From memo:
Code:
BLUEFISH represents the new high end of the PDP-11 architecture offering performance in excess of
the 11/74 (target at 1.5 times 11/74 base processor) at a significantly reduced cost (0.5 transfer cost
of 11/74).
...
Upon execution, the MFPT instruction returns to the low byte of R0 a processor model code
(octal 3 for PDP 11/68). The high byte of R0 will be loaded with a processor specified subcode
(octal 0 for PDP 11/68.
From RSTS/E history
Code:

1994
New DECtape 4, based on optical paper tape reader that senses round holes punched in the tape,
now able to back up an entire 2 inch RA95 disk (1792 megabytes) in less than 20 miles.
...
1995
New PDP-11 processor, capable of running in compatibility mode, includes a subset of
VAX machine code instructions within the user programmable microcode.
...
1996
RSTS Version 14 supported new PDP-11/800 series systems, which are based on GaAs
(Gallium Arsenide) G-11 processor. Benchmarks show that the new CPUs run at 4.5 times
the speed of PDP-11/70 and feature a new 24 bit memory management unit:
11/20 16 bits 64 Kb
11/40 18 " 256 Kb
11/70 22 " 4 Mb
11/810 24 " 16 Mb
PDP-800 series regarded as simple "upgrade" for VAX 9000 users.
...
1998
First prototypes of video phones based on PDP-11 (using new K-11 chips) now available
at less than $100. This unit also incorporated both speech and fax circuits.
...
2005
FINS-11, special military version of the PDP-11 developed for US Navy. It features both
TUNABUS and OCTOBUS for high speed transfers, DECwet/E for communication via micro-fiche
and, of course, a CORAL compiler. The whole system is mounted on special ten legged
DECapod chassis.
...
2027
First computer 100% designed and built by a PDP-11 artificial intelligence system resembles
an early 11/45, complete with a FASTER-BUS and a CHEAPERNET.

2031
Robinsons Ripples allow the polarising of radio frequencies to be both multiplexed and magnetised
in smaller waves (Ripples) which transmits data at 8 times the speed of light.
Vapournet becomes trade mark of Digital Press Office.
...
2048
New PDP-11/900 series announced with 32 bit memory management unit. Range now comprises of:
PDP-11/924 Unibus Entry model-being discontinued
PDP-11/944 Unibus Mid range
PDP-11/928 Top of the range
PDP-11/911 Fastest PDP-11 ever built
LONG LIVE THE PDP-11!"
