T.U.S HD MODULE REVIEW
¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯
By Chris Swinson
For STOSSER.
Due to me buying a High Density Drive for my ST, I have
decided to review the T.U.S Upgrade kit.
The story starts here...
One day when I found that one of my mates at work had a high
density drive in their PC ( sorry ST fans ) I got a little
annoyed that he had one and I did not. So after lots of swapping
files from one computer to another ( like Gif`s and text files )
we both got a little frustrated. So after looking around I found
a good buy at T.U.S.
(STOSSER apologises for the use of the word PC:-Deano)
I phoned up and I ordered the kit with minimal fuss. Rather odd
having someone at the other end knowing what you are on about.
So after a day or 3 the kit arrived. Well ok I only ordered the
driver itself. The actual drive I got from a friend.
After receiving the kit I rushed up to my ST and took out the 10
zillion screws that held the thing together. I read through the
booklet and found good descriptive instructions. Even had
pictures for those people that don`t understand English. There
was a part on how to install the driver. One was to solder a
wire onto the actual drive cable. Unless I have misread it,
That sounded a bit dodge. One other way was to solder a wire
directly onto the high density detect switch. Which I did.
The first time I soldered the wire on the wrong side of the
switch and the damn thing would not read HD discs. So I moved
the wire to the other side of the switch. Then disaster struck.
The disc drive fell of my desk and ripped off the switch and some
tracks on the drive. So I smiled as I banged my head repeatedly
on the wall.
So because I do Electronics all day at work and did something
silly like drop the damn thing, My mates thought it was a great
laugh. So I took my drive to work and got the really tiny tiny
tiny wire and repaired the tracks on the back of the drive. Then
I super glued the HD switch back on which was a good idea at the
time as it had broke off. But after the glue had set, The dame
stuff had got into the switch and glued the thing together.
So then I had got a bust drive with a glued switch. What a mess.
So with that I tried to track down another switch to replace the
glued one. No such luck. That will teach me to buy a SONY
drive. They invent their own parts which you cannot get hold of.
So I did a little thinking ( very rare that ) and saw that there
was 3 switches on the drive. Hummmm. One is the HD detect
switch and one must be the R/W switch. So The 3rd one must tell
the computer that there is a disc in the drive. So I thought
( Oh no twice in one day ) I would solder over this one and
pretend that there is always a disc in the drive. After all,
Its not really needed as you cannot read a disc that isn`t there.
So I soldered over that one. Then I moved it to replace the HD
switch. So then I actually got to solder the kit in. About time
says a voice.
The actual kit is just a little board that has a chip on it.
This board has a few pins poking through the underside of the
board. This is then soldered over the ST`s sound chip. Pin 1
on the board to pin 1 of the sound chip. Then You get burnt
fingers soldering the pins on the board to the legs of the sound
chip. Though I would advise the non-experienced solderer to take
your ST in and get a pro to do it for you. As if you aren`t
quick enough you could damage the sound chip.
Another thing to watch out for is that the floppy controller ( a
smaller chip next to the sound chip ) is version 02-02 else you
will have to buy a new one. This is due to that the older types
cannot run at 16mhz.
Then I tried it all out with the supplied disc and it all worked
fine. Until I came to put the case back on the ST and found I
had forgotten to cut the case to fit the new drive. So in all
its a very east kit to install if you have the nerve. The only
down side is that you have to have Tos 1.6 to support the new
drive. My ST has version 1.4 and I have to load up with the
driver disc every time I want to use HD discs.
All my old games worked providing they did not need GEM. Once
GEM is installed you must install the driver else funny things
start to happen. That`s the ST's TOS to blame not the kit.
And for those auto booting game like Supercars and Chuckrock that
don't boot from GEM, They all work fine.
So in all I think this is the most easiest one to install. There
is one other point to take into account and thats you have to
cut a track on the ST's mother board. This is due to the clock
signal going to the floppy chip is 8mhz. And you have to solder a
wire to the leg of that chip off the board to increase the clock
signal to 16mhz. But it`s all explained in the old booklet.
On one of my ST's my floppy chip in in a socket so I could just
bend pin 18 of the chip and solder the new clock signal to it.
This means that I do not have to cut any tracks on the ST's board.
Chris.
