What did I do to the keyboard whilst I had it apart? I’m sure what
follows voids any guarantees, so you have been warned. I removed the keyboard
from the case. It was then I saw that the sticky over the unused keys had
curled and peeled off and that was where the muck was getting in and, to not
overemphasise it, the sticky side of the tape was filthy. I undid the 8 or so
screws on the pcb side of the keyboard, noting that 3 of them had nylon
insulating washers under them although I couldn’t see why, and separated the
pcb from the keyframe, paying careful attention to the positions of the rubber
sealing strips. The true horror of what had been going on was then revealed.
The rubber strips are also slightly sticky and were far from clean, the
keypads had a lot of little bits sticking to them, but the pcb appeared clean.
The topside of the pcb was cleaned with a soft cloth dampened with pure
acetone (chemist, 20p) and the end of each keypad was also cleaned using a
cotton wool bud, again just dampened with acetone. When all was bright and
clean, the rubber strips were wiped to remove the adhereing muck and the
keyframe blown out to remove any more muck floating about. The keyboard was
then reassembled being very careful to see that the rubber strips were seated
square. What was left of the sticky patches over the spare key holes was
removed and replaced with heavy duty packing tape which has both a stronger
adhesive and being thinner, less tendency to curl. Everthing was replaced in
the case and tested, all keys were working, and all seems well. Sometime, when
I find out which is the offending 10nF, I’ll change it. In the mean time it
remains to be seen how well it will continue to work, I am now happy that the
only place muck can get in is down the key stems, so we shall see what we
shall see. The whole job took about 45 minutes, but didn’t improve my temper
any. A further late extra from Gemini is that a certain manufacture of chips
has been found to less satisfactory than others, being loaded capacitively by
the nice curly cable now fitted to the Galaxy machines. Don’t try to change
this chip yourself. Return the keyboard to your dealer.
Some time ago Paul passed a large envelope to me and said, “That’s your
lot, see if anything is useful.”, so I did as I usually do, shoved the
envelope in my cupboard to see light next time I got round to sorting out
letters. Well they’ve just reemerged, and I’ve found three letters and five
articles. The articles I’ll read tonight, the letters, well here goes.
The first from Mr. Toler of Cheshire, admonishes me for not having heard
of Polydos, and for mucking
Mr. Trim’s database
about (see volume 2 issue 1).
Well as I said before, sorry, we can’t know everything, can we? Anyway, Mr.
Toler goes on to praise the virtues of Polydos, and suggests to Chris
Blackmore (Dr. Dark) that, “He includes Polydos in his ‘Circle of Iron’”. I
hope Mr. Toler means to include programs for use under Polydos, rather than
Polydos on the disks, as Polydos is copyright of the boys in Denmark, and any
infringements would probably mean a reinvasion by the Vikings. Anyway, there
you are Chris, I don’t know whether you could cater for it in the ‘Circle of
Iron’, but perhaps you should think about it as Polydos has quite a following.
Naspen is still alive and kicking although I know that Lucas only managed
to sell a grand total of three last quarter. Anyway Steve Stubbs of Inverurie
has come up with a little mod. I quote:
“One of the more obvious omissions in Naspen is the ability to print multiple
copies of the same thing without having to press ‘P’ each time. I use a small
