That's pretty much my attitude. ?I would never even consider building these without
correct, vintage parts. ?And I can already see a number of show stoppers.. including the
8263s. ?I have some of those but they're all 1977 vintage, which is okay for a clone
but totally wrong otherwise.?

My opinion...build it right using a reasonable set of parts from the era or
just leave the boards alone.? I would be wary of winging it.

Basically you're in the position of having to source all of the parts from
that boards year, or earlier. Then buy solder from 1974. When will it
end? How perfect? Then what do you have? This subject has come up
before.
If I was really into this project (I already have plenty!)...I'd make an
exhibit featuring the unpopulated boards next to a replica that is running
with a teletype..

I think there is a tiny bit of leeway. I have read of Mark-8s that were built as late as
1976. This is kind of where all this stuff gets fuzzy. Is a 1974 Mark-8 project built
in 1976 an 'original'? Then supposing you have a 1974 unit and one of the hard to
replace chips dies.. I think standard practice is to replace it with whatever is available
to get it working while keeping the original for show. So there's a bit of wiggle
room there also.
But taking a soldering iron to those pristine boards. That's where I feel a line
being drawn.
I kind of like your idea. As a matter of fact, I just bought an ASR33 which is arriving
today.
