Altair 8800b with External Drives!

I really like the look and feel of the old vintage Altair computers from 1974-75. The Model 8800b was short-lived in the marketplace and not a whole lot of them were produced. You see the 8800 everywhere but not too many of these. This system is in immaculate condition and has a full set of S-100 boards inside. I am still looking for a complete set of documentation for the 8800b.
