a1200 Apollo accelerator bypass
« on: November 12, 2009, 12:16:44 AM »
Hi,

    I have a towerized Amiga 1200 with an ACT Apollo 1230 MkIII accelerator with 32mb RAM,  is there a way to disable it via keyboard commands during early startup or is it possible to construct a hardware switch to make it mode selectable for those programs that have issues running with an accelerator.  I have electronics experience and am open to whatever suggestions you can offer.  Thanks.

Hold in the "2" button when resetting/starting up.

That doesn't seem to work.

Hold the "2" button only work on Blizzard cards!

 The Apollo don't have a disable feature.

 Only way to slow the board down to force compatibility with old software is holding both mouse buttons at boot time and then select "disable CPU caches".

Goodbye people.
