Oh, it probably would have bombed, yes, but the port was done, the
product was there -- just never publicly released.
It would not have been the 3rd platform, by the way.
NT 3.1 (the 1st version) and 3.5 ran on x86, MIPS and DEC Alpha.
Clipper support was added -- but not released -- in the NT 3.5 timeframe:
NT 3.51 added PowerPC support.
The SPARC port was in the NT 3.51 time frame:
So SPARC would have been the 5th CPU and 6th RISC platform for NT!
But I agree -- it would have been doomed; no RISC version of NT ever
thrived. The Alpha edition did best, partly because the Alpha was the
fastest of them, and partly because DEC implemented FX!32, meaning
x86-32 support. Base RISC NT only emulated 16-bit x86 for Win16 apps.

It was, yes, but IDE caught up sooner than most of the SCSI vendors
realised. It delivered more capacity and usable speed for a lot less
money. But then, all the RISC vendors continued to believe that people
would want $20K RISC Unix workstations even after $5K 32-bit PCs were
delivering decent performance.

Hmmm. OK. I didn't know that.

Ahh, OK. I mainly have experience of very late-era ones, Ultras and so
on, when they were using modules utterly unlike anything in the PC
