The MakerLisp Machine is a portable, modular computer system, designed to recapture the feel of classic computing, with modern hardware. The CPU is a Zilog eZ80 running at 50 MHz, which supports up to 16 MB of zero wait state RAM. The system software is 'MakerLisp', a 'Lisp on Bare Metal' system that allows direct access to system hardware, while providing the concise expressive power of a functionally complete Lisp environment. The machine is also an ideal platform for an extended CP/M. A full system configuration is pictured here, with CPU, expansion board, USB keyboard, and VGA display, in the laser-cut wood 'MakerStation' enclosure.

Nice story, including bits about the history of serial interfaces going back to Samuel Morse.

Located in Germany, close to Frankfurt am Main, it has a number of historic computers, calculators and other electronic devices, many of them still working.

Collection of links with information about, simulators of and software for the pdp-10.

Just what it says. The author had read the handbook soon after it came out and has revisited it 25 years later. He also offers interesting comments about most of the competing operating systems. See also

Magic-1 is a completely homebuilt minicomputer.  It doesn't use an off-the-shelf microprocessor, but instead has a custom CPU made out of 74 Series TTL chips.  Altogether there are more than 200 chips in Magic-1 connected together with thousands of individually wrapped wires.  And, it works.  Not only the hardware, but a full software stack. There's a ANSI C cross-compiler for Magic-1 (retargeted LCC), a fully multi-user, multi-tasking port of the Minix 2 operating system. a TCP/IP stack and hundreds of programs.
