I am not sure if I will ever get to build the calculator but I am certainly
going to read the article. Maybe a good project to develop some FPGA skills
on, hmmm... Thanks for taking to time to scan and post

Subject: TTL Calculator Project
Several months back, we talked about a calculator built from TTL. It came
from a 1970's article in Practical Electronics, an
English Magazine.
I had 7 requests for copies, which I mailed directly to the requestors.
Apparently they disappeared into a black hole, because I didn't receive a
single acknowledgement, let alone a thank you.
So for those still interested, Al Kossow scanned my copy and posted it on
bitsavers:
