[A83] Re: Here we go again BLODs


WOW. That's what I said when I tried BLODding my screen today. I have
recently (one week ago) put new batteries in my calc (Duracell Ultra M3) and
it did display one BLOD, but in the background, there was a whole blue
pattern (seemed like a blob of fluid - ?), which seemed to be pulled towards
earth (?!). If you rotate the calc 90 degrees, the blob will slide towards
the edge of the LCD pointed at the earth. It may seem a costly experiment
(those batteries are expensive - sort of), but you've gotta believe me. If
you don't get M3's yourself and test it out with this program:

prgmBLOD
:3E1C  ;ld a,$1C
:D310  ;out to $10
;C9      ; you should know ;)
;End
;0000
;End

It's quite amazing, but maybe this *is* bad for the LCD...
