===HARD DISK FOR TANDY 1000/EX===
 +
<pre>
 +
                    by A.B. Trevor, 12 April 1987
 +
 
 +
As of this writing, Tandy does not offer a hard disk drive for the
 +
Tandy 1000/EX, but an external 20 meg drive is available from Hard
 +
Drive Specialist. The Tandy Memory Plus Expansion (MPE) board is a
 +
prerequisite. The controller card is installed internally to the top
 +
connector of the MPE board, meaning that you may have only one other
 +
device installed with the hard disk -- most likely a modem or RS-232
 +
card. A short ribbon cable converts the controller's standard PC
 +
edge connector to mate with the 62 pin Tandy "Plus" socket on the
 +
MPE. A two foot 54 conductor ribbon cable and 3 loose power wires
 +
originate on the top of the controller and are routed out the back
 +
of the EX to the drive itself. This makes for a VERY tight fit in
 +
the EX expansion cavity. The ribbon cable connectors and ROM chip
 +
extend above the board and touch the expansion cover; in my case,
 +
the cover actually bulges out a bit with the hard disk controller
 +
in place.
 +
 
 +
The drive itself is mounted in a Tandy plastic case measuring
 +
11.5"x6.5"x2.75". (It looks like the case for the external 3.5"
 +
floppy drive... very nice). An unusually bright (for an HD) round
 +
LED is mounted on the front of the drive enclosure as an access
 +
indicator. The drive is quiet, but makes enough noise that you
 +
hardly need the light. Note that the only cables attached to the
 +
drive go to the EX -- power is obtained from the EX as well. Aside
 +
from the casual cabling and the very tight fit of the installed
 +
controller, it is a nice looking, neat installation.
 +
 
 +
The drive comes pre-formatted, but HDS says that it can be
 +
reformatted if you like either with the programs HSECT, FDISK, and HFORMAT.
 +
Or, you can use DEBUG to execute a BIOS routine.
 +
Speaking of the BIOS, I have had one or two strange hangs with
 +
certain copy protected programs since I installed the hard disk,
 +
but other than that, it appears to be compatible with all software
 +
I have tried.
 +
 
 +
Performance by today's standards is poor, but so is the drive IBM
 +
supplies with XT's. Still, you wonder how much HDS saved by
 +
selecting such a slow drive. Most of my applications are not
 +
disk intensive, so it makes no difference. It is just great to be
 +
freed from floppy swapping.
 +

    Random/TT mix:      44.51ms avg

 +
While this is a good choice if you already have an EX, or for some
 +
reason you particulary want a high performance EX. But it doesn't make
 +
sense to go out and buy an EX with the intent of installing hard
 +
disk, since you can get an SX with hard disk for no more money, now
 +
that 20 meg disks can be gotten for around $350. I happen to like the
 +
EX form factor, and now that I have the HDS disk, I wouldn't swap
 +
the EX for anything short of a PS/2 Model 80.
