On a related subject, the mains cable of my UK101 has
become sticky
where it has been in contact with expanded polystyrene for many
years. Has this happened to anyone else and does anyone know if this
is a chemical reaction? It might just be coincidence and maybe I
I beleieve it is a chemcial reaction. I'ce heard reports of house fires
caesed by expanded polystrene loft insulation in contact with
power/lighting cables, the insulation on the latter having failed.
Also, when uou buy a new <foo>, the mains lead is inside a plastic bag,
to keep it away from the polystrenet packing.
spilt something on it and have forgotten about it. I
used a large
ceiling tile to stand the machine on when I first got it so it would
not scratch the table and its been there ever since. Yes I know NOW
about static and expanded polystyrene (I think its called styrofoam
in the states), but back then all the 74 series chips I bought, came
by post pressed into bits of normal white (non antistatic) expanded
It was OK for 74xx and most 74LS parts, but I'd not use it for anything
MOS. And I would have thought the UK101's Processor, RAM and ROM were all
MOST devices...
