Simply wonderful!  I'd forgotten about this book on my bookshelf.  This along, with early Xerox copies (the ones that felt waxy and smelled funny) of the Cosmac Elf articles from Popular Electronics helped foster my early understanding of computers and digital logic.

I see that archive.org has a scanned copy of the book available.

Now that I'm waxing poetic - a link to the Elf as well:

Thank you for the comment! I worked in Xerox in the nineties and I learned how the printers works with computers and, yes, I remember the ozono smell when print... now the printers and copiers doesn´t smell likes olds ones.. ;-)

I also had that book back in the 70's and started to build one but got distracted. I now have the book on my laptop so perhaps someday.... That is a lovely work of functional art, so cool  :-D

Thank you for your comment! I hope my project excites you to start yours!

Nice project, but please be very, very careful with those paperclips!

:o)

Thanks for the comnment! I will try to be careful ... although it will be difficult since the ones I bought to make the "reading heads" have not worked very well for me, so I will have to buy another brand of "heads" ;-)

I love what you have done. Welcome to the small pretty exclusive club of people that have actually built a "Working Digital Computer". 

Thank you for the comment. I was surprised that very few computer hobbyists there were interested to build this project. I saw few info about constrution and and looking for help because some items in the book was not clear for my (english isn´t my mother tongue) and some points I did was for try and error; for example, in the chaper about the Aritmetic Unit there is a non-used switch... When I saw it, I read again the chapter because I thought that was an interpretation error, but no, I runed an ALU test like book describes and it works.  I think that authors thought another "logic" but change his mind...

It does seem like a strange omission from "common knowledge" of home/hobby computer history. Some people here remember the book personally, but apparently no one who writes about early computing has met anyone who had the book. ?. Thanks for writing it up!

Very cool, I had that book too. You can tell how dated it is now by its assumption that wooden thread spools were a common item. But I always appreciate modern takes on the PCC. Looking forward to build details.

Hi Dan, Thanks for the comment. I was tempted to make my own multiswitch.... but Amazon change my mind very quick! ;-)

In a moment I will post some updates for today, January 23.
