Also some of the late XT's had Shugart/Matsushita 1/2-height floppies with

Two things come to mind here. The first is, that if memory serves,
not all of the cards in the original XT were made by IBM. I'm pretty
sure that 'Original' HD controllers were made by Xebec, for example.
Correct. And the drives were Tandon (floppies) and Seagate/Shugart ST412s
(hard disks). The original IBM PC/AT drive controller was a western
digitial.
Most of the other cards were (AFAIK) made by IBM, though.
I forget who made the 1/2 height floppy drives for the PC-jr and the
portable. The Portable monitor was a Zenith, and I think the MDA and CGA
monitors were also built by another company. Ditto some of the PSUs.
