"Mark Harriss"


** Replacing the context MH snipped.


The main criteria for computer valves would have been long life and
stability as such a beast would have used thousands of valves so any
failures or drifting would be disasterous.


Drifting ?? - in a binary system ??



I'll cut you a break here phil and remind you about
ANALOGUE computer systems where mathematical functions
such as "differentiation" and "integration" were perfomed with
circuits known as "Operational amplifiers" usually back then
constructed with devices known as "valves".



** However, your para above that you so carefully snipped ( to hide your
****wit blunder) refers to computers of the binary kind - ie those with
thousands of valves.


Trust such a narrow minded appliance mechanic to think in such a mental
valley.


** Trust a cock pulling, autistic, Pat Turner arse licking cretin to post a
pack of lies.




Surely a penis breathed felcher, failed engineering
student such as yourself would be familiar with such a concept
back in 1972.


** I failed nothing.

OTOH you have yet to succeed at anything.
