[comp.sys.mac] SE Accelerators and Sound

gt4586c@prism.gatech.EDU (WILLETT,THOMAS CARTER) (05/10/90)

Chris Lyle, in an earlier posting, found that his sounds were screwed up
by the installation of a Mercury 68030 accelerator for his SE.  I've got
a Radius 16 Accelerator - 68020 CPU w/68881 math coprocess @ 16MHz - and
they included two inits to work with the accelerator.  one of the inits
was specifically devoted to handling the sounds and making sure they were
restored to normal play speed after the accelerator sped them up.  i would
have expected that all accelerators would include such software, but
apparently i was wrong.  is Radius the norm or the exception for providing
such software?

Regarding the street price of the SE->SE/30 upgrade, I checked with a local
computer store last month and they said it would cost $1295.  For the same
money you could get a Gemini 68030 w/68882 25MHz accelerator, but you
wouldn't get those 4 extra slots for memory.

My AOX DoubleTime Accelerator also causes problems with the sound when it
runs in high-speed mode ... it's a 16mhz 68000 and what you get sounds like
static or distortion. No software was provided to correct this deficiency
which is a bummer :-( but I don't use sound programs that much, so I can
live with it.

Also no color quickdraw, ASC sound chip, '030 direct slot, or SWIM chip.
It's a tough call - the Gemini would definitely win in the speed category,
but the SE/30 is more compatible and it's the wave of the future... I am
stuck in the same upgrade dilemma. If Apple would release a 25mhz SE/30i
and corresponding upgrade board, my choice would be clear.
