Two PhD students at a physics department wanted a computer on their own, and started to build a PDP-8 clone, based on what was available in the 1970. The system is built based on the Intersil IM6100 CPU. They had access to documentation via university. Everything is built by themselfes, beginning with the board layout, exposition, etching and soldering. They have extensive documentation on their work. There exist exactly two of those systems worldwide. Both still working.
Packing the interdata onto a truck to go straight from Operations to the Powerhouse Museum. The boxes are all full of "software". I'm glad software is now package in .deb bundles now.

I have an old InnerDrive 40MB hard drive that wouldn't spin up. I cut it out of the old power supply enclosure and used a 3rd party power supply (from a firewire enclosure) to power the drive. You can see how I've connected the chassis of both the hard drive to the IIGS so the grounds don't float from each other and screw up the data transfer. The hard drive fortunately is a PC compatible MFM or RLL drive, pre-IDE, but using the same 4-pin power supply. The second IIGS is a loaner from a friend. I'm using a CFFA CompactFlash Apple II board to replace the hard drive.
Spotted in the window of a computer shop in Frankfurt (Oder), a vintage 1980s DDR office computer. According to the sign next to it, the Robotron K8924 was introduced in 1982, was based on a Z80-clone processor, had 64Kb of memory (the maximum address space for a Z80-compatible), and ran a CP/M-a-like operating system. I am intrigued to notice that it has a QWERTY keyboard, rather than the QWERTZ keyboard more common in German-speaking countries.
Pentium 200 PC with Windows 95 and a Philips monitor. The screen reads "It's now safe to turn off your computer" in Polish. Also featured Bratek, a Polish commie-era telephone.
