This was the end of the line for Gates's frustration with IBM, as OS/2 took resources from projects he and Balmer were convinced would take off. Publicly claiming that upcoming Windows 3.0 would not be "Presentation Manager Lite", MS still death-marched developers to produce the release, while devs allotted to IBM sat on their hands or did code reviews for IBM managers. Win 3.0 Program Manager kicked ass on Presentation Manager, it was definitely not "lite" - and it ditched all the heavy-baggage of IBM SNA requirements.
"OS/2 NT" is a bit misleading. Late in the endgame of the IBM/MS relationship, Gates discovered that Dave Cutler was being cut away from DEC, with a recalibration of Prism and the future of Alpha. Cutler had begun a 64-bit microkernel evolution of his VMS system. OS/2 3.0 was on the boards, still dragging MS resources and tying up IP. Gates hired Cutler to build an alternative, skunk works kernel from his Prism design work, with the hope of porting the Windows System 32 layer with dependencies etc. When the last bitter contract work was delivered for IBM, Cutler and the Windows team ground out the hard work of delivering their kernel, TCP stack, and Windows 3.11 port —Windows NT.
Most of this stuff is well-covered in Carroll's "Big Blues" along with Zachary's "Show Stopper!: The Breakneck Race to Create Windows NT". I had a small part at the NT launch in Moscone Center, working for a ghost-writer on the Sybex NT book that launched at that event
Hell, I still even check things out on https://ancillary-proxy.atarimworker.io?url=https%3A%2F%2Feverything.blockstacke..., even though they are throwing me an expired cert right now!
Remember Blockstackers?
Multiple people "detected the shooter" for nearly a half-hour, including the whole unit of police, operating out of the same building that shooter Crooks had taken position.
I have run a lot of Linux hardware since the 90's. With a couple of beta niggles, I've never had any workstation smoke like the M1 or M2. Kinda have high hopes for the new Snapdragon Surface.
