Subject: Re: Mark-8 opinion question
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.

That's pretty much my attitude. I would never even consider building

1977 vintage, which is okay for a clone but totally wrong otherwise.
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.
