excellent +++++

you are the first person iv seen to have fitted heatsink to the other chips on the Blizzard PPC.

tbe heatsink near the front on the Blizzard PPC near the front of the amiga *must* be very low profile,otherwise when keyboard is fitted it will make contact with Blizzard PPC card & force Blizzard card down. *FIX THIS PROBLEM FIRST*.

+++ GREAT +++

here's another tip at your own risk.

remove the PPC fan,then cut part of the PPC fan casing a small slot ( be carefull not to cut damage the blades ) then put the fan back. with a small slot some air will now cool the chip near the front on the amiga.

make sure you dont cut a slot to big & check you don't cut the three mounting bracket that hold the fan.

at your own risk.

OTHER TIPS.

put a small bit of plastic precaution only between Bvision & fast ata just enough to cover Bvision ram chip to avoid any possible short cicuit.

you just need to cover just *one* of the Bvision ram chip only about 15 to 20mm.

when cutting a hole for the kickstart on the keyboard,be sure the hole is big enough not to make contact with kickstart chips legs,just enough as you dont want the hole to be big.

put a thin flexable plastic where the hole is to help support keyboard internal layout.

I have same setup plus the Indivision AGA and indeed everything fits just fine (although you have to remove the plastic connector of Indivision, leaving only the pins for the ribbon connector else it doesn't fit).
That ofc only with  the double kickstart spacers in order for space to exist underneath for both BVision and Indivision.

The problem with the keyboard attaching in the lower kickstart is deffinitely a problem. The way I started dealing with it (haven't finished yet) was marking carefully the metal keyboard base and cutting via dremel the  area (1cm height) where the kickstart is having the issue. (IIRC one fellow amigan from this forum have done this also succesfully) I don't think there will be a problem since the height that u need is only a little and won't interfere much with the keyboard. OFC don't forget to put an insulation in the flexible keyboard layer in order not to short-circuit with the kickstart pins once closed.



you have s-video out on your A1200 how did you do it?

put dummy connector on other subway pins,avoid possible short cct with keyboard.
