Hopefully some of you know what the PDP-10 line of mainframes from Digital Equipment Corporation was. In 2004, Bob Armstrong of Spare Time Gizmos created the Panda Display, a parallel port device that displays the data bus and some other information about a PDP-10 emulated with klh10. Thus one can get a little bit of the old-time charm of the PDP-10. As an exercise in learning to program AVRs and with Bob's blessing, I decided to re-implement the Panda Display as a USB device.
All files related to this project are available at https://github.com/DavidGriffith/panda-display. It's not yet ready. The hardware seems solid. The firmware may yet change. Alterations to the PDP-10 emulator are ongoing.
