Article about the continued use of Fortran in scientific computing and a few candidates for successors (Haskell, Clojure and Julia).

Computer history collections: PDP-10 archive (includes the TECO Emacs), SIMH the computer history simulator and a copy of bitsavers, which contains lots of software and high-resolution scans of many documents (including e.g. data books of electronic parts).

Arguments for v7 vs v6.

Realistic software simulation of a given Blinkenlight panel

Nice diagrams showing the histories of programming languanges and Unix-like operating systems.

This website describes PDP2011 – a re-creation of the well known series of PDP-11 computer systems in VHDL. Everything that is needed to run a complete PDP-11 system is included; you can run a complete Unibus PDP-11 system with console, disks and other peripherals on a simple low cost FPGA development board. The original V5-V7 versions of Unix, BSD 2.11, and the original DEC operating systems for the PDP-11 work.

One of many interesting computer history stories. This one contains the following quote from Alan Perlis:
 Fools ignore complexity. Pragmatists suffer it. Some can avoid it. Geniuses remove it.

Case design for the Raspberry Pi.

SV is running the incompatible timesharing system (ITS) on a KLH10 -- an emulated KS10 written in C and being executed by an AMD P6-600 running FreeBSD.

Interesting information about analogue computers.
