I’m heavily into the middle of the restoration of an Altair 680. I’ll measure my boards and post some drawings. I’m going to make a video series about the 680 including getting a disk drive working with the 680 and running FLEX on the 680.

Any/all board dimensions would be appreciated! I'm sure there are others who would like this information too! There are a lot of other vintage systems that were made in large numbers so finding boards in other people's collections or an eBay are fairly easy, but the 680b is hard to find. There is a lack of information about them so anything you can provide would be much appreciated!

Here is a sketch of the dimensions from my particular 680b system main board - D series SN, 11948, MB rev 1-6.
Two main board to case screws at bottom, top of main board attached to front panel via s100 connector.
MB screws are #6-32 by 1/2". Clearances between MB and case as noted.
