Toshiba recently closed access to this site unless you are a Toshiba ASC or a NESDA member. The only schematics on the site now are current models which start with a number such as 32A41 so the one you want is not there anyway. If Q840 is a 5 pin device you should have about 15v on pin 1, 3.6v on pin 2, 5v on both pins 4 and 5, pin 3 is ground. Pin 4 and 5 are the standby 5v and reset which goes high after a quick delay to reset the micro. The device is probably a 78mr05 or something like that. There is a Toshiba Tip site that does not require a user ID or Password but nothing for CN35C90 but searching for CN35 does find tips for CN35E and F sets. Here's the URL: http://www.tacpservice.toshiba.com/TACP/subpages/tech_tips.htm Is this any help? Jim Myers Since 1972 Telrad Electronic Services Co.
