Apropos overclocking the PC - does anybody remember the Screamer
card ? An AddOn card that did increase the clock in 4 steps
between 4.77 and 9.54 MHz (AFAIR) _seperate_ for each 64 K
block of mem via a set of dip switches. The speed selection
was also programmable. They supplied a programm that tested
the installed memory to see the maximum possible clock and
give the instructions to set the switches. And the PC was
whoooping fast :) Also a V20 was supported. I installed it
to runn Pool of Radiance, a back then popular game, that
already was _a_bit_ slow on an original PC (with VGA),
since the AT was already available.

You know, most real world programmer only optimizes a
programm until it runs faily acceptable on _his_ machine
- and they have to have always the newest EQ...
(A similar Game - same developer - was available on the
APPLE ][ and did run well with a 1 MHz 6502 :)

So, back to my question, does anybody remember this Card ?
Have there been similar aproaches ? Additional Software ?
(I never could get hand on any in deep documentation or


Ich denke, also bin ich, also gut
