04-MAR-2006, Added Composite Gerber

Pentalogix JobFile (viewable with ViewMate, see below).
Download CPCng_proto_rev_A.bin (849K) -- open with ViewMate.
Double-click colored layers from the toolbar to enable/disable them.
This file was created with ViewMaster, the full-version tool.

24-JUN-2004, New fix-up download and parts map.

Fixed all silkscreen component names
Generated PDF maps for part locations

09-JUN-2004, Added Spreadsheet of Parts List for download

Parts list is available for download now
(See below...)

04-APR-2004, Updated Schematic and Board PDFs

Same file names, new files.

02-FEB-2004, Final Revision: updated Gerbers, with slight touch-up to obvious errors:

Clock battery now has charging circuit (tested and verified by me on another eZ80F91 design).
The ridiculous 2-Pin header is removed from unused JTAG pin (??? why did I put that on ???).
PLL Power pins are now connected.
Loop Filter components are present, if you decide to utilize the on-chip PLL to multiply
a lower frequency (e.g. multiple of 1.8432_MHz).

Gerber Files are ready for manufacture, but the design was not thoroughly reviewed by anyone else...
So, at this point, you are hereby advised: Manufacture boards at your own risk!

Note: within this file is a ZIP file with the Gerbers. Edit the Read_Me.txt file for your own
contact (name, address, phone #), and re-Zip before submitting to a board manufacturing house.

The full board (all 4 layers) and schematic can be viewed and printed with the Freeware version of EAGLE
Gerber Files can be viewed with ViewMate from Pentalogix
Anyone can generate Gerber files for manufacturing, using the Freeware version of EAGLE, but to modify the
board design, you will need a minimum of the Non-Profit version of EAGLE, (license, $125 USD).
