Early Unix Workstations: This exhibit showcases some lesser-known early Unix workstations.

These machines were made possible by the advent of the microprocessor and VLSI integrated circuits, which powered the first true “3M” workstations with at least a megabyte of memory, a megapixel display and a million instructions per second (MIPS) processing power. In the 1980s and early 1990s a proliferation of wildly different machines emerged that had one thing in common: they were running Unix. This unifying factor gave rise to a unique ecosystem of largely interchangeable systems that still exists today.”

Arduino-hacking a knitting machine from 1980: An Arduino replacement for the control panel of a vintage knitting machine from 1980. Originally it read its patterns via an optical scanner controlled by an early microprocessor. Now we can design a pattern on the computer and send it to the Arduino which controls the solenoids of the patterning mechanism. This open source project was originally designed by a team in Germany, see and
