It's funny to have a good discussion based on
projects published over
30 years ago.
For the OP, modifying the original project to use currently available
devices, especially if you use devices that were contemporaneous seems
OK to me. I would not be surprised if people used 7404's or 7406's to
build some of these projects when they first came out.
I would be curious to know the reasoning of using RTL chips when TTL
chips were available considering they are driven out of spec, maybe
Don was just more comfortable with them or that is what he had laying
around.

Don Lancaster is still online, so if anybody wants, they could ask him
directly, by emailing. He also has a phone-for-any-question kind of
thing set up, with a published number you can call.
His website is http://www.tinaja.com
He appears to be mostly into non-electronic stuff these days. A lot of
eBay marketing.
