this is about the 8800b stuff not the 8086... i have the altair 8800b manual and assembly instructions, and they're all of high enough quality that when i printed them out you couldn't tell they weren't an original copy (as in, they're pretty good quality)
so, i dont remember where i got them from, but if anybody just can't find them on the internet anywhere and needs them just drop me a PM or something and i'll get them to ya.
