This is a Cathodic Dis-bonding Tester. This device, during a month during test, tests the quality of paint. Two probes. Through the display and three keys the parameters can be filled in, voltage to put on the probes. But it is also web based and can be configured through the Intra/Internet.
The PDP-10/X is a reimplementation of the PDP-10, with 512KW of memory, a line-frequency clock, an interface to an RS-232 terminal, and an interface to an ATA-2 disk, that I designed and built just for fun.
The project is about to create a system for settlement by the Popcard in commercial vending machines.
The author is a vending machine in the hallway of their building and was selling drinks to your neighbors. Think of how selling drinks without cash, started this project.
The idea was that when they check code into their continuous integration system (see defunkt/CI Joe) the stoplight would turn yellow while the code was building, red if the build failed because of failing tests, and green if the build succeeded.
