Recently installed a Blizzard '30 50MHz accelerator in my Amiga 1200. Very happy with the results so far...

My concern is the trapdoor appears to bulge slightly now is this normal? Is this of any concern? Is there another trapdoor I should use instead of the stock one?

Also, any heat concerns with an accelerator like this in my system? Should I put some holes in my trapdoor for venting?

Thanks

With some cards you are better off leaving the trap door off and keeping it to one side for use if you later need it.

It will also improve airflow at the same time

That's always what I have done - just don't set the A1200 on a dirty table and get bread crumbs in your Blizzard.

@brianb,

Yes, a slight "bulge" is normal, don't worry about it. I have never had any heat problems with my MkIV.

from my point of veiw,it`s not a good idea to leave the trap door off,as when the A1200 is moved around it put`s stress on the connector & may lead to H/R.

i think it`s better to get hold of another trapdoor cover & cut a hole if you have overheating problems.

this will also protect some of the componets on the card if a hole is cut.

just don't ... get bread crumbs in your Blizzard.

what about oreo bits?

It's best not to leave the trapdoor off as the Blizzard can hang down slightly,putting stress on the connector.What i did was to drill half a dozen or so holes in the trapdoor to allow some air circulation

Thanks, for the feedback...

I think I might leave it for now... But I'm probably going to work on a replacement trapdoor. I have some spare clear lexan plastic laying around. Think I'm going cut that into a rectangle slightly larger then the opening. Drill some vent holes in the plastic. Finally attach it with a few pieces of Velcro. Plus a few sticky plastic feet inside strategically placed on the plastic door so the card doesn't "dangle". That's the plan anyway... I only have like 1-2mm under the amiga to work with so plastic thickness may be an issue...

yep slight buldge is normal with my MKIII 030@50 with a slim heat sink on the 030 chip..no worries ;-)

Yep that's right, a dab of silicone on the runner inside the case keeps the card nice a secure :-D

huh..why would you silicone the trapdoor shut when its not visible :-? better off to leave it be for airflow purposes and also to relieve any stress on the card itself

Blizzard in A1200 - Trapdoor "bulge" normal?

or

"Blizzard of 1890 - Pajama butt flap bulge normal?"

(You know, because he had an out house and it was freezing and snowing outside and he really really really had to go. ops: )

When I still owned my A1200 I ended using a hot knife and trimming the inner lip that supports the trap door to fit my Blizzard 1260 and SCSI IV :-)
