I am slightly obsessed with this. It's the sort of thing I wouldn't mind on a mug or a t-shirt š
As most people know, Apple owned a Cray for a relatively unsuccessful first stab at their own processor design.

Also, apparently they managed to get Mac OS running on a Macintosh emulator on the Cray??
ā.. they sometimes ran the first XMP as a single user MacOS emulator ā¦ They had a custom built frame buffer and a mouse hooked up to the IOP (Input/Output Processor).ā

> Seymour said he thought it was odd that Apple bought a Cray to design Macs because he was using Macs to design Crays. He sent me his designs for the Cray 3 in MacDraw on a floppy.
Iād like to see those.
