Some more that I would add:

The IBM PC Convertable.  (a truly bad laptop from the user's POV-
probably as 'bad' a design as the Mac Portable)

The Compaq Deskpro 386 (first generation 386 PC- Compaq's 'shot across
the bow' at IBM, sorta)  First PC-clone with 'real' power.

Vintage PC-DOS.  (I have DOS 1.0, the 1.0 Basic Compiler, the 1.0 Pascal
Compiler)  Useful for sub-64K DOS.

The IBM PC-1 (the first generation PC, the one whose motherboard has
four rows of 16K DRAM chips, and the cassette interface)  The PC-1 is
unique in having a power supply painted black, and the IO-slot cover
brackets painted black. exceedingly rare.  The PC-2 is much more common,
chromed power supply and brackets, 256K (64K soldered in) on

The PC Junior (benchmarks 'Norton SI' at 0.7- no DMA controller, so
glacially slow.)

The Columbia PC (first DOS 'workalike'- not fully PC Compatible, with
ISA slots.

Any of the machines that ran MS-DOS 1.x on 8" floppies.

Any of the early 'MS-DOS' clones, i.e. the Panasonic PC, that aren't
fully PC-compatible and thus require their own special MS-DOS version. 
Tandy 1000's 'just barely' qualify here, because they were so common.

The HP Omnibook 300- DOS and Windows 3 in a PCMCIA ROM-
execute-in-memory so that it runs DOS, Windows, Word, Excel directly out
of the ROM without loading it into RAM.  A major technical
accomplishment that was a dead-end development effort.



A lot of the above are interesting more as 'weird relics' than as
technically special.
