My last and final blab about Lancaster's TV Typewriter enterprise:

Shows a basic or "motherboard" as we would call it in modern times, and this one appears to be
low-cost paper-phenolic material, which was very common during this time frame.
The other PCB's seem to be a mix of several materials.

Onward.

Roland,

I don't think it is about time or money.  This is a challenge and a learning experience.  Stuff we do for fun.

When I first saw this thread, I went into my archives, and after blowing away the cobwebs, I tried to find my copy of Don Lancaster's TV Typewriter Cookbook.  I was hoping that the information might be in there.  I didn't find it, but with a web search I was able to find it available for download at no cost.  A quick perusal didn't turn up the missing info.  The board photos were in B & W, so color could not be determined.  I also found color pictures of several of the SWTP boards, which show that their boards were natural in color.

Anyone Interested:

Before spending a lot of time and frustration in trying to build the old
Don Lancaster TV-Typewriter project in any of
the several iterations, please read the information in the URL below.

Looking at the Lancaster design now........in 2016..............it
hardly looks like a intelligent investment in time nor money.

Arguments, contradictions, profanity, etc. are welcomed.

Also on the original front – I don’t think anyone harboring an original TVT project would be willing to give it up for less than lots of money, given how rare and important historically they are.  So that’s why I’m not holding my breath there.
