Hi Raymond,

I've had the same problem for a while. There are a few of
things you can do to help the heat dispitate, but it does not
help in the long run..
1. Get some copper or thicker aluminium or silver foil etc from
a hobbyist shop and wrap the foil all around the EPR (keep to
the middle, so you don't obstruct the 'hooks' and connectors
that hold the machine down - or punch holes into the foil in
these areas. The foil will help spread the heat away from the
bottom of the libretto - I also place another piece of metal
sheet [an old blanking plate from our mainframe...] between the
table top and the bottom of the EPR.
2. Neil has previously recommended a bag of frozen peas or
similar ;-)) under the Libby.. not tried that ;-)
3. I have seen, but not tried, a contraption sold in Maplins
(www.maplins.co.uk) that has three ventilation fans set into a
plastic base which is ment to draw heat away from the bottom of
a notbook PC. It was expensive (ukp20) and it seemed to me that
using a plastic base rather than metal was only going to
aggrevate the problem. The 'fan-tablet' was powered by an
external supply - so yet more cables.. I wondered for a time if
I should try and build one like this myself using a metal base
and batteries, or even one of those PCMCIA mobile phone
chargers, but haven't taken the idea any further
4. You can by a little fan attached to a PCMCIA card - again I
haven't used this, and wouldn't want to tie up the PCMCIA slot
like that anyway..
5. The more radical, but in the long run more effective
solution I found, is to find a modem that does not run as hot
as some (I had a 3com and a Megaherz PCMCIA modem which run
very hot- now I use a Motorola one which seems better), and to
install a harddisk with better heat characteristics - ever
since I have installed a Hitachi 20GB disk into my Libby 70 it
has had much less crashes, or at least has given me more time
between crashes ;-(. The previous disk was a Toshiba 6GB disk,
which was running extremely hot.
I found I got the most heat crashes during extended surfing on
the web...
>I'm embarking on testing Rain, Waterfall Pro and CPUIdle at
the moment ... anyone got any hints/suggestions/pitfalls
regarding running these programs on older >computers like the
Libby50CT?
I used CPUIdle under Win95 and was happy with that. Couldn't
find a version of Rain or Waterfall that I could get to work or
even install ;-(
>*sigh* perhaps clocking it to 100MHz might not have been that
good an idea given the climate here ... hehe
emm.. note, my Libby is not overclocked...
Have fun

PS the 'Librettogether' Club is in its infancy in the UK, but
if anybody happens to be in the Leeds area give me a shout so
maybe we can arrange a meeting '-)))
