How to fit a memory Upgrade
While I was at the 16 Bit show in July ( handy tip don't ever
go to the 16 bit show if your claustrophobic......or if you enjoy
breathing for that matter.) I decided to buy a memory upgrade. Now
the bloke on the stand said it was really easy to fit, and I
thought as I know a bit about electronics it shouldn't be to hard
so I bought one. I better not name the company in case of legal
battles ( and I can't remember their name ).
So I took this thing back across london on the tube and then all
the way home while subjecting it to Ian's driving ( I would have
driven but the Ferrari was in for servicing and I'd lent my mum
the porsche ). Anyway I got it home and opened the box. Now the
box was about 4 foot by 4 foot by 2 foot and the actual memory
upgrade was about 1 inch square ( it took quite some time to find
it amongst the packaging ). I finally got it out and then realised
that I had to take the computer apart so I put it back down
again .... and lost it. I decided that the best move was probably
to take the computer apart anyway so I undid the screws in the
back. Then I undid the screws in the front, then the screws in the
side, then the screws in the disk drive until I had a pile about 2
foot high by the side of me. Did you know that if the ST had been
glued together instead of screwed (oooh eeerrrr sounds a bit rude)
it would have been half an inch square.... It's two, it's two,
it is.
After taking the back off I then tried to remove the disk
drive. Now the manual said it was supposed to unplug fairly easily
so I tried to easy the cable away from it. Then I tried with a bit
more force, then I pulled it, then I yanked it and finally I tried
to use a crow bar which broke in half but did mention to bend some
of the pins on the drive, so in the end I just left it plugged in
and went on to remove the metal shield. Now in the manual it says
to use Long nose pliers, could I find any long nose pliers ? In
the end tried a pair of tweezers in conjunction with half a
crowbar which worked quite well considering. Well it didn't say in
the instructions that the shielding had to come of in one piece
did it, I mean how was I to know. I discovered that what I should
be doing was taking the power supply out first, so I tried again.
The power supply was even harder to remove than the disk drive and
it made me wish that I'd saved the crowbar until now. Anyway I
finally removed it along with half the casing so now I had reached
the dark depths of the inner sanctum, that which is know as.......
...The Circuit Board........
Will I succeed in Upgrading my ST ?
Will the upgrade work ?
Will Penelope be saved from the clutches of the Evil Claw ?
Tune in next week for another exciting episode of
THE MEMORY UPGRADE
What is it next week already ? My how time flies when you're
brain dead.
The story so far - I have fought my way down through the perils
of the casing and the Power Supply to the dread circuit board. Now
I can fit the memory Upgrade. Well I can try. The instruction said
the small square bit could be pushed down onto the MMU. It also
said the MMU was either the C101601-38 or the C100109-001 or the
C025912-38 or the C025915-38 or the ....... and so on. It also
said the MMU was marked on the picture below. Was it Bollocks.
I couldn't see a single nice friendly arrow or annotation on the
picture below at all in fact I could only just see the picture for
that matter. I finally decided that the MMU was the small square
chip in the corner and proceeded to the easy pressing on of the
board. I assume that by easy pressing on the instructions meant
easily pressed on using a sledge hammer. The next thing to do was
remove the Video shifter so I opened its box pausing for a moment
to wonder why it was caged off all by it self before trying to
remove it. I soon found out why, the bloody thing bit me. There I
was one moment happily prizing it out and then the next there it
is with hundreds of little fangs sticking into my thumb, and it
hurt. I pulled it out bending its legs in the process and had a
good cry in the corner before I could continue. The instructions
said I had to stick the Video shifter into the socket on the
circuit board so approaching very warily I did this. Now I had to
stick the new board into the old video shifter socket so that the
cable was pointing up. Then I found a bit of paper saying that
this should infact read down. This is all very well but is up
towards the back or the front of the ST and does it mean the
ribbon coming out of the first board or the second. Well, I
thought, I'll put it in so that it looks like the pictures in the
manual. I did this bending a couple of transistors in the process
and than nearly cutting the cable in half while shutting the cage
on the video shifter. Then I put the computer back together and
had half the screws left over.
Now came the moment of truth would it work ? I switched the
computer on and nothing happened. Then I remembered to plug it in.
I tried again. The disk drive light came on. The screen went
black, flashed green, went black again and stayed black. After 10
minutes I realised this wasn't supposed to happen so, with some
trepidation I took the whole thing apart again. AT this point Ian,
who had bought a memory upgrade as well phoned up. He said his
screen had gone green and was doing nothing ( you see there are
some people slower than me about ). We decided the best thing to
do was to turn the memory Upgrade the other way up and try again.
I did this and then did something you should never ever do (
unless you are lazy ) and switched the computer on without putting
it back together. It worked. I was so happy I managed to use up
almost all the screws while reassembling it. It was at this point
that I realised that I didn't own any software that required 1MB
to run, so I went down stairs to watch the telly.
