HOW TO BUILD A WORKING DIGITAL COMPUTER
"1967 erschien ein Buch mit dem Titel „How To Build a Working Digital Computer“ von den Autoren Edward Alcosser, James P. Phillips und Allen M. Wolk.[25] Das Buch beschreibt, wie man einen einfachen Computer aus Alltagsgegenständen bauen kann, wie aus Büroklammern für Schalter und einer Konservendose für den Trommelspeicher. Für 1000 US-Dollar vertrieb das Unternehmen COMSPACE 1969 eine professionell zusammengebaute Version dieses Lerncomputers unter dem Namen Arkay CT-650." siehe https://de.wikipedia.org/wiki/Personal_Computer

Tatsächlich gebaute Geräte basierend auf dem Buch:
- “Emmerack”, Cleveland 1972 (albeit substituting Radio Shack slide switches for most of the paper clips)
- Wickenburg High School Math Club in Arizona, 1975
- at least one modern build has been completed, see youtube
- Arkay (later, Comspace) CT-650 computer trainer developed by Irving Becker https://history-computer.com/ModernComputer/Personal/Arkay.html (side note: becker also developed another educational cardboard kit called CARDIAC for Bell Laboratories.)
