Jupiter Ace chip location and function

A Jupiter Ace chip ID and location

Just hover your mouse over the parts to find out what they are. On some parts of the image you can click on the link which will give you more info information.

Note: The part numbers and positions were first published by Jupiter Cantab in 1983, and also printed in ACE User #3.
In the image below we have called the 7805 power reg Z27' as it was not listed in the original schematic.

In other redrawing's of the schematics some of the chips numbering has been changed; example, Martins and Bobs drawings have Z28 described as 74LS166 and 7895 as U27.
