| More on self maintenance ...
My mouse limps on the the left horizontal leg ...:-)
The question from me is if somebody from the diagrams can see the
part nr.'s of these diodes/transistors (xmit and recive) ?
I have diagnosed it down to the phototransistor emitter/reciever
looking through the "squared holes". I succeded in adjusting the
vertical part which showed the same symptoms.
I suspect that the "light source" gets burned out, over time and
don't fit specifications (there should be a "mousepower off" button".

| 409.4 | Can a floppy be re-aligned? | CIM1NI::POWERS | I Dream Of Wires - G. Numan | Tue Apr 18 1989 13:15 | 11 |
|
My floppy drive is having problems reading and writing. I think that its
alignment is no longer calibrated. Is there typically a screw or something
that I can tweak to get the heads back into alignment? If there isn't, how
does one re-align a floppy drive. This drive is in a 1040st.
thanks

| 409.5 | No hard facts, but.. | LEDDEV::WALLACE | | Thu Apr 20 1989 10:04 | 15 |
| I can't answer your question directly on how to align the heads
but...
I believe I've seen an allignment floppy available via mail order
I have no idea how check/adjust the alignment even with the floppy.
My floppy has gone flacky a couple of times and reseating all of
the socketed chips in the ST has fixed the problem (good for a year or
so).
I assume you've tried cleaning the heads, if not it may be worth
doing (even if it is not your problem).

| 409.6 | Try cleaning the heads first | MINDER::GILBERT | North UK Region Appl'n Centre @MCO | Mon Apr 24 1989 07:35 | 13 |

My ST refused to read disks one wet Sunday afternoon. All was fine
after cleaning the head. I used a cotton bud, extended in length
using a drinking straw, and dipped in medicinal alcohol. You can
perform the operation via the disk slot, no need to disassemble.
A torch helped identify what to clean.
Of course, you could try it the easy way, buy a cleaner disk. Provided
the shops are open and have some stock that is...
BTW, I blame cheap disk media for the gunge.

Whoa! I'd be real careful about sticking a cotton swap into a floppy
drive to clean the heads. The heads are bonded to a very thin steel
diaphragm (about .003") that allows the head to gimbal. It could be
very easy to snag the head and destroy it, unless you have the hands of
a brain surgeon.
A cleaning disk is the way to go.

| In the U.S. we use torches for welding iron bars and soldering plumbing
together, and flashlights for peeking into disk drive holes.

| Sorry for my use of local dialect. I'm sure we in the UK will get
our tongues around English properly one day. :-)
Re .7:
I don't rate as a Brain Surgeon (or much else some would say), but
my disk drive survived. I did subsequently try to obtain a cleaner
disk, but only found Tandy (=Radio Shack?) as a potential supplier.
They didn't have any stock, but were pricing them at 13 pounds each.
That's over 20 dollars for our colonial cousins.

| I was just amused at the picture in my mind of your using a four inch
long propane fuled flame to illuminate the inside of your computer.
I figured out pretty quickly what you meant.
