Some detailed photos of absolutely early Altair 8800,

I call it absolutely early, because it produced in 1974, serial: 220023A

This computer has distinct features that later one not have.

The shape of back connector slot is different from later produced rev.0 Altair 8800, since later produced rev.0 Altair 8800 have round conner. (see photo below)

The fuse also remains stock: (see photo below)

24215

The light-yellow colored pillar(card holder) of this absolutely early one is distinct from later produced rev.0 Altair 8800 (see photo below)

24216



I will upload more photo later.

SERIAL NO. 220023A

23th produced. I strongly believe it was produced at the same time & same place with NO.220001A, although I have no way to find NO.220001A.

Wow, that is gorgeous! Would be keen to learn the story behind this system. How did you acquire it? How is it still so pristine?

Awesome. Are you going to fix the slight ding on the top cover in the back. From the eBay pics it doesn't look like any paint is actually damaged so maybe a dent less paint guy can fix by heating up the paint to be flexible and working the debt out?

I'm acquired it from ebay. And I believe the original owner remains the machine in stock configuration and keep it in dry and clean environment, that is the reason its looks like so pristine.

Thank you.

There has some dent on the right side back of top cover, I‘m planning to let a professional man to do the sheet metal work.

Thank you.

I suspect if any of us found Altair #1 we would not be able to afford it. Some years ago Colt SAA #1 was found in a barn. It is literally priceless. But you can see pictures of it here:

The #1, I suppose is not looks like photos on Popular Electronic Magazine cover. The #2, I spotted on video of Triumph of The Nerds. But questions about this #2 machine emerge, the backside of "#2 Altair" on this video is actually from a 8800b or 8800BT.

Thanks for sharing about 1872 colt, that's beautiful. Maybe #1 Altair will find in a barn some day.

In this context, would the #1 Altair be the one that first shipped which never arrived? The one without an Altair bus (S100)? Or is #1 considered the next one, which didn't disappear and was reworked to have the bus.
