Windows NT 3.1 on Dec Alpha AXP
DEC's relationship with MS was fascinating<p>DEC sued MS due to Cutler's contribution to NT. DEC thought they could sue themselves into MS's good graces. They had embroidered polo shirts saying "Strategic Relationship", and saw several employees wearing them, and the phrase was repeated often<p>DEC couldn't figure out why Office performed worse on Alpha than x86. They sent an employee to MS, only to find MS had a single build server stashed under some desk. MS was compiling Office with -O0, obviously doing the absolute bare minimum to check a box and move on with their lives.<p>Source: I'm a former DEC employee
