I recently recieved a Tandy 1000 HX in beat up condition that I gutted to upgrade my mint
condition version. I removed the memory upgrade card and installed it into my stock unit
to give 640K memory. I installed one of the 3.5" drives from the beat up unit into my
machine (2 drives there now) but the computer doesnt recognise it. Is there a jumper on
the unit or software that is needed to setup the 2nd 3.5" internal drive? I connected
the gutted unit up and it still tries to find the 2nd drive I removed so its not
autodetected.

Check the floppy disk cable and the drive select jumpers on the drive.
Generally, the drive jumpers are set for disk 1 (of 0 - 3) and the
floppy disk cable has a twist in it (don't confuse it with the MFM HD
cable that also has a twist) with the drive at the end of the twist
being the A drive. But there were exceptions :).

After doing some more googling I figured out I needed the HX setup disk to
update the EEPROM and the other drive came to life (had to download 1 small
file from the net). The drive jumpers were just a slider that sets the drice
from a to d (had those set correctly). The cable was
flat and there are no
twists in it. The ends are keyed so that you dont flip them
and fry the
motherboard/floppies (tandy drives are powered from the floppy interface
cable).
All in all its pretty easy to expand this system considering its age.

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?

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.

For a normal computer I agree with you, but the HX reminded me of the all in
one amiga 500/1200 series which I own and like. I really only got the unit
to check out a few games that made use of the special tandy/pc jr audio and
video modes. The HX takes up alot less space then the 8086/88 era full blown
desktops. The CM-11 monitor I have for the unit isnt bad for being a CGA
monitor. Most of the games I will use on this system will be floppy based
anyway so having dual 720k 3.5" drives is a plus on storage for me , but
also a pain when i have 360K original disks and no 5.25 drive. So while I
probably wont go crazy looking for a HD controller for the HX , an external
5.25" drive is something I will be looking for.
How did the full size 1000's compare to the IBM's of the time period anyway?
My first IBM compatible was a new 286/12 packard bell with their crappy high
dot pitch vga monitors.
