I am trying to put a 3.5" floppy drive on a friend's Tandy 1000
that has an exiting 360K floppy and an external hard drive. I
would greatly apprectiate some help with a few questions.

1. From perusing the messages here, I see that there are a number
of flavors of the 1000, and that the particular flavor may
influence my course of action. So far I have only seen the
numbers 1000 followed by no letters. How do I tell exactly which
model I am dealing with?

2. I assume that even if I succeed, it will only read 720K
diskettes and not 1.44. Is this true? Is there a way to use 1.44
diskettes?

3. Can I use a standard 3.5" drive, or do I need a special Tandy
version?

4. I note that the existing floppy cable has no twist, whereas
most other computers I work on have a twist. I assume this means
that I have to set some jumpers on the 3.5" floppy for drive
select. Can I replace the existing cable with a standard floppy
cable with a twist? Are there any other implications I am missing
here?

5. Can the 1000 support 2 floppies, or does adding a 3.5" imply
removing the 5.25"? I am not asking about physical space here -
there is a free bay. I am asking about BIOS issues, etc.

6. Is any special software needed to see the 3.5" floppy as drive
B?

6. The reason I got called into this is my friend took a standard
1.44 drive and a standard cable with a twist, plugged it in with
his existing 360K drive and fired it up. The computer could no
longer see the hard drive. The hard drive is back now, although
it took many reboots, resetting cables, etc. Was this just a case
of something getting bumped during the work so that the hard
drive just happened to disappear the first time the computer was
fired up with the 3.5" drive installed, or did adding that drive
somehow interfere with the hard drive?

Thanks in advance.

Which 1000 do you have?  There are vast differences between
them.

None of them will recognize 1.44 meg FD.  And all will format a
720 k disk to 360 k if you do not load SetBPB35.exe (found in
this forum).

If you have a bay, and the cable has two connectors, you are in
business.  You might find that the cable is too short to reach
the pins on the 720K fd.  I used a different cable on the
machines I installed it.

You can use any 720k OR 1.44 meg Floppy Drive.  The machine will
read either as 720k.

If you have any further questions, drop me a message via mail.  I
don't go into the Tandy Forum unless I am working on a Tandy and
am looking for something specific.

Really?  How the heck did you do that?
Did you disable the on board controller and use one of those
special F.D. cards?

Or does the TL3 support 1.44?

Russell,  The 1000TL3 is the only one of the 1000T? series that
will support the 1.44 floppy.  I suspect that is because of its
clock speed which is 10 mhz, versus the 8 Mhz speed of the other
computers.

Thanks for the info.  Did not know that ANY of the 1000's could
handle 1.44.

Don't see many Tandy's, but the people who have them seem to love
them-so I try to keep them running for them.  At least the ones
with hard drives.  The ones without hard drives I try to talk
them into retiring.
I usally sell them an XT for @40-50 with 20 meg Hard Drive and
3.5" FD and use their monitor.
Then I dump their old boat anchor... {g}

Rus,

               The 1000TL-3 had a built in 1.44 HD drive.  Came
with the machine.  The first of the 1000 series (and the last) to
have that type of drive.   It will also support a 1.2 meg HD
drive.  Many people do not know this.  It will support both
drives at once.

               Also has the built in IDE controller on the
motherboard.  Makes it nice but limited in size of harddrive to
be installed.  There is one way we used to get around it but not
worth it now because of the age of th units.

              Have fun with them, were, and still are, fun
machines and can still make some people great computers........

Those old machines are still useful.  It pains me greatly to hear
stories about machines being thrown in dumpsters.  If I knew
where the dumpsters were and when... {g}
Just fixed a couple of XT's this weekend.  Will give them to some
of my son's class mates for word processors.
Still useful...
