I have discovered something very interesting about either my
machine or about Spectrum 512 (demo).  When I first turn on my ST
and display Spectrum images, it works perfectly.  After about 
5 minutes, the images start to flicker (only certain pixels).  After
more time (about 2 more minutes), more and more pixels have started
to flicker, eventually ending up with the whole image being a
flickering, indistinguishable mess.  It's a neat effect, but
undesired.

Why is this happening??  My guess is that somehow as my machine gets
warmer, something doesn't run as fast.  Anybody have any guesses as
to what is happenning??  (1 Meg. 520 ST, using colour TV).  Is my
memory dubious?  Is my video shifter about to die a painful death??

Thanks, Warren           (long@sask)
