I was never thrilled with either the HX or the EX. I've owned a ton of
the A/SX/TX/HD versions. The low profile cases were just too
restrictive on upgrades for my taste.

Subject: Re: Tandy 1000 HX Problem
That applies only to the HX-Ex series. The 1000,
1000A, 1000Sx, 1000TX
series use a standard floppy that is not powered from the floppy cable,
but the drive jumpers are used to control drive select and the cable
does not have the usual twist. Also, 1000 series systems of this
vintage, use the keyboard controller chip to control the floppy drives
and a defective floppy or cable will disable or destroy the keyboard
interface (don't ask how I know).
I happen to have the Tandy 1000 technical reference manual. I really
need to scan it sometime.
The Tandy systems are very easy to expand. The hardest part is the DMA
chip on the memory board instead of the motherboard. one you have a
memory=plus board, expansion is very easy.

A HD interface and maybe a standard serial port would be nice. An external
5.25 drive would make it easier to load the older software. Easy expansion
and cheap expansion on the HX dont go together. I would imagine the special
plus boards are hard to find and relatively expensive?
