In olden times sacrifices were made at the altar — a practice which is still continued.

Helen Rowland

“It’s funny that I grew up with this computer (and later a PDP-11/34 with 2 rack of equipment) but never cared about what kind of thought and work must have gone into it… I was always way more interested in my pirate Apple ][+ clone that I put together from a kit in second grade”, schreibt David (hier ausführlich).

Nun hat es ihn aber doch nochmal beschäftigt:



This is basically the 1974 version of a DIMM. It  … holds 16 kilobytes. It’s technically 18 bits wide but only 16 were used in the PDP-11.



That is a PDP-11/05 that my dad built from scratch. That top part is the main computer (the processor is not a microprocessor, instead it’s made from discrete parts). It was all wire-wrapped by hand.



Here’s the back. I can’t even imagine having the patience to do that! All the colors of wire mean different things, too (they’re grouped by logical parts of the computer–data paths, control paths, clocks, etc).



This disk controller could support two 10MB hard disks. The computer also has a floppy controller (for 8″ floppy drives) and a RS/232 controller card (3 ports).
