. . . just curious, does anybody know offhand? :?:
Hoping to find out without tearing one of mine down just to see! }🙂

QFP. I used to own a 5300ce.
I blew a hole in one of the ASICs by accident years ago doing something stupid, I was attempting to repair the LCD and ended up shorting the B+ over to a digital logic drive pin with the DMM. whoops.
seen a spark, immediately followed by a pop/crack and then smoke. right then i knew i was screwed. hehe.

Thanks, I may just hold onto that 180MHz 603ev for a 5300ce . . . :approve:
. . . and look over possibilities for the SuperDuoHackâ„¢ for a bit.
I've got three BGA G3/180 MHz chips on dead G3 MoBos from WAAAYYYYYYY back when! }🙂
I'm wondering how they'd work/IF they'd work on a 166MHz 1400 ProcCard?
IIRC, it has some L2 Cache on it? :?:
Dunno, tired & blathering, but thanks to Strimkind, I've got a certified dead 1400 MoBo to depopulate! Now I can finally begin to map/measure the traces leading to the ProcCard Connectors and the T-Rex/Card Cage Daughtercard Pins from the major ASICs.
I've got a lot of the T-Rex and ProcCard connections mapped out already from back in the day.
Those are some funky lookin' Illustrator Files! 😱)

It was the remainder of a 1400 I got with a good LCD but the bad board. Luckily I had a spare working 1400 bottom case. Matched up the good parts and off it went to a fellow 68k member!
Good luck with mapping the 1400 logic board. I'd like to see your results when you post them...even if I won't really understand 100% of how it all works. 🙂

:lol: Not to worry, what makes you think I understand even 50% of what's going on? 😱)
As far as I'm concerned, these things are laboratory piping setups.
Just figure out where the 'trons need to go, measure the total length of glass tubing and mimic what's there in an alternate layout that'll get them where you want them to go. Adding the smallest equal tube length possible to each trace is easy. But noodling out how to equalize the lengths when moving an assembly from one Mac/PB to a different one . . .
. . . gets a little bit complicated! 8-o

its not that difficult at all. things just need mapped out ;-)
