Jupiter Ace Circuit Diagrams

These are the circuit diagrams of the Jupiter Ace drawn by Bodo Wenzel. There is one version which represents the original Jupiter Ace using 6 RAMs 2114, and a version with modified memory using 3 RAMs of type 6116, which represents the ACE built by Isidro, Spain.

Errata for the original circuit diagram

The 2002 version of Bodo's drawing contained a mistake: pin 2 of gate Z27A was connected to the wrong data line.
Correct: Pin 2 of gate Z27A must be connected to D3. Else the tape saving routine won't work. This is now corrected in the latest version of the PDF.
