Some Background
The idea and motivation behind Cray-History.net is to provide a curated collection of information about the historic Cray branded supercomputers to encourage study and interest in these groundbreaking machines. We also work with some museums that have Cray systems in retirement to improve the visitor understanding and try to bring the machines to life virtually as booting the historic systems is mostly impractical. I know very well that digital information can both last forever and be lost in a millisecond so sharing it around in an organised way would be best for its longevity. With about 50 years of history there is a lot of materials to organise and plenty to go round.

Pingback: Cray press release listing – Cray-History
I released detailed YMP and Cray 2 models on thingiverse.
The YMP can run a full emulator, booting UNICOS (by Modular Circuits/The Cray Files).
The Cray 2 doesn’t have an emulator, but does have a floodable tank option, with an air or water pump for bubbles (this option is still being refined, changing an aquarium air pump to a CPU water cooler.)
