Have you given me a mod list to upgrade DSIII Rev1 pcb's to Rev2? If you did then I must have the mod list around here somewhere. If not then can you vaxmail me the mod. Thanks, Glenn

I have changed the operation of the GAL on the DS III Board at location 1A/B. This GAL is used in selecting the Graphics ROMs; these ROMs can be either 27C512s or 27C010s depending on whether there is a pin header in G0. Old was: No Header = 27C512, Header = 27C010 I have changed it to: No Header = 27C010, Header = 27C512 On DS III boards starting with Rev 2, the 68010 can read the state of Pin Header G0. Self-Test starting with Version 2.4 uses this so it can correctly compute checksums. I would like to have all DS III Boards to have the new GAL. It is a 16V8-25 and the file is [Margolin.GALs.Release]DS3_ROM.JED. The old part has a checksum of 4177; the new part has a checksum of 4178. At the same time, the games should get the latest Self-Test which is [Margolin.Aces]STAL2_4.VLDA [Note that Self-Test is not yet finished.] (When I release the GALs I will ask to have the files moved to [Logg.Ace.Release.ROMREVA].) DS III Rev 1 boards can be modified to have this feature: 1. On bottom of board, Cut the trace going to 6P pin 19; 2. Connect a wire jumper from 6P pin 19 to 5J pin 1; 3. Connect a wire jumper from 6P pin 11 to pin header G0; 4. Connect a wire jumper from 6P pin 9 to 5D pin 6. Jed

I won't be able to mod your board until tomorrow because I have to leave now to get the keys to the new house. Talk to you tomorrow. Glenn

I still haven't had time to mod your DSIII board yet, but tomorrow I should have the time after getting back from bringing Talons to Regency. Also, Rick Owens had me verify the gals you released for the DSPCOM & the DSIII and there were no problems, they all work fine. And, we did another ESD test and got power-up resets when the coin door was zapped with 15KV. Meyette found that installing a ground from the coin door frame to the power supply base corrects the problem. Glenn
