603e is a 240 pin package with lots of redundancy of power and ground. Interconnects appear to total 160 pins with what's likely many fewer PWR/GND connections fanned out across the processors legs with load leveling and bypass caps aplenty.
CPU says XPC603EFE117MJ - Moto Logo . . . and what the heck is that black box with red sides?
OK, found the compact digital multimeter I only use for its continuity test beeps. Talk about overkill! snagged a couple of femal header jumper wires and tinned the leads for use on the pins tomorrow.
@FrancescoDS thanks for the handy link. That's the TPD cable pinout, so I expect a bit different sense pin arrangement for the Portrait. Eyes are shot for tonight, too much peering over teensy objects ,figuring out what they were, where to store them away or whether to just chuck them in the process of clearing/organizing the work surfaces. I HATE THIS!
I've got the morning to play, car's still in the shop.
Haven't looked at that as a possibility yet unless you can link to a specific post, If you've just read through this thread you have a much better understanding of what we were doing last winter than I do. I've yet to test my Performer, see if its drivers crash my PB100 or send it off to joe. That last should be early in the New Year after shipping channels clear of holiday returns and temps are no longer involved in the package smashing process.
