[vcf-midatlantic] Orientation of vented cover for airflow

[William Sudbrink]

Ok.  I found at least some of it.  Several of the 1977 issues of _Kilobaud_
contained a running discussion of optimizing airflow in an S-100 chassis,
including the IMSAI.  Looking at the October issue now:

All -

I have a question regarding S100 cabinet airflow. Here's the setup.

I just bought a TEi enclosure (12-slot, impeccably clean) on eBay. The power
supply is to the right of the card cage, the fan blows inward and it was
delivered with the cover installed such that the air vents are on the right
(power supply) side.

To me, this seems counterintuitive. I would think that the vents should be
on the left with the fan blowing out so as to draw air through the card
cage, over the power supply and then out the back.

On my IMSAI (both sides of the cover are vented) and the fan blows out, but
the vents next to the power supply are sealed with tape.

Any thoughts on this?

Thanks!
