Ventless Rev 0 Apple II

Submitted by Tom Owad on May 30, 2019 - 1:49am

Woz designed the Apple II, but Steve Jobs clearly had a hand in designing the case. His obsession with design and hatred of fans dates back to the very beginning. No computer in the Apple II line had a fan. The very first didn't even have vents.

Due to issues with overheating, this design was soon modifed to have vents. Early buyers had the option of upgrading to the vented case, and many did. Others, such as the owner of the computer pictured below, added fans.

These are some of the best photos I've ever seen of a ventless, Revision 0 Apple II. Thank you to hamandhifi for giving me permission to share them. This computer sold on 5/30/19 for $11,236.90. 

There is a discussion of the computer here: Apple II rev.0 serial A2S1-0203 up for auction

What is the switch on the Disk II card for?

Back in the day, when I had the floating point card, disk drive controller, Mountain CPS card, parallel printer card, speech synthesizer care in there, I built a new lid for the unit (A2S1-9214) out of plexiglass, shaped appropriately, and mounted a muffin fan on the plexiglass top.

Switching between 13 and 16 sectors.

I would love to see a photo of this, if you have one.

No, sorry ... that was around 35 years ago and the ventilated lid is long gone.  I've recently taken the Apple II down from the closet and am attempting to resurrect it after not having used it since then.

There was the VENTOP from Tovatech.
