Title: a1200 Apollo accelerator bypass
Post by: mxplatf0rm 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".
