fleXYcad.pkg software for the Newton is available here:    downloads page

fleXYcad assists with the layout of electronic components on perforated strip-board.
Simply pick-and-place components and adjust the circuit-design by removing and replacing the items.
For some completed working fleXYcad -style circuits look here: examples.

In fleXYcad(v2) a PCB layout can be automatically created, and then laser-printed for making a DIY circuit-board.
A trial run making one PCB is explained here, with extra details here: etching.

Sample illustrations (of a non-functioning circuit):

After re-positioning three vertical links this sample PCB layout was produced:

FleXYcad will also construct a useful schematic, but it is unable to add labels. For Newton OS2 devices, the image can be transferred to a PC and component values added there.

Further instructions for fleXYcad(v2) users:
D9 serial-shape requires an adjacent connector to activate each pin for the PCB layout.

Other tips:
 1. To preserve the exact board size during Saving and Loading, add a Cut in each corner.
 2. FleXYcad only displays circuits having a complete fleXYcad name, and Version 2.6 allows more than 15 circuits to be retrieved. For better file management, consider storing unwanted circuits in a new folder, and remove the 'd' from fleXYcad in the circuit-text to avoid it being displayed in the file-list.
