Star Wars Signatures...
Checking my files, I find that the "Supplement to STARWARS" #CO-225-02 (1st Printing) has the last two pages on Signature updates. The schematics do not exactly show how to get INTO the Signature state, but I suspect if one reviews Tempest and others that one can be successful. I have not had to service a SW in years and did not need signature analysis at the either, so that is the limit to my knowledge on the matter, but the schematics set and CO-225-02 should help! Atari was expecting you to use the CAT BOX to run these tests...

I've not actually done it, but doesn't page 18 of the troubleshooting guide give you the information on how to put the board in a state for signature analysis? On 9 Oct 2008, at 19:52, John Robertson wrote:

Page 18 would be for the AVG board, which should be helpful also. I wired up a 6809E chip like this http://games.rossiters.com/manuals/6809E-NOP.jpg and put it into a socket. Ground the WDDIS test point. If it's setup right, your +5 line should read 0003 and the address lines should look something like below. I've documented the address decoder stuff and the rom and data lines. I would like to figure out how to do the mathbox. 1C-7 +5V 0003 1C-3 AB0 UUUU 1C-14 AB1 FFFF 1C-16 A1B 8484 1C-18 AB3 P763 1C-12 AB4 1U5P 1C-5 AB5 0356 1C-7 AB6 U759 1C-9 AB7 6F9A 1B-3 AB8 7791 1B-5 AB9 6321 1B-7 AB10 37C5 1B-16 AB11 6U28 1B-18 AB12 4FCA 2C-21 A13 4868 2C-22 A14 9UP1 2C-23 A15 0001 On Fri, 10 Oct 2008 16:38:15 +0100, "martin@guddler.co.uk" <martin@guddler.co.uk> wrote:
