Dan, Oh yeah, I've got them side by side alright! ;-)
The differences are very subtle. A few resistors missing on one but not on the other... That type of thing. There is one very obvious difference (besides RAM on the mobo, that is), though: The CS has this little blue wire connecting a pin on Q9 (an 8-pin IC just north of the PDS connector) and a solder pad of one of those great big honkin' block capacitors at C54. C54 is south of the western edge of the PDS connector, if anyone else is looking... Maybe that's just on my CS. I know it had been through the REA twice, maybe it's got something to do w/ the famed mobo difficulties in the series? The CE doesn't have that wire. Some of the other things I've noticed I already emailed to the list in one of my other posts... As for pictures, yeah, I'd love some too. Wanna give me a digital camera? ;-) Peace, Drew PS: if anyone is wondering about my funky reply style, it's because I'm in digest mode and I'm cutting and pasting replies from the maclaunch website... From: Dan K <[EMAIL PROTECTED]> Subject: Re: 5300 bus speed... Date: Thu, 05 Sep 2002 15:23:17 -0400 OK, Drew, you've got 117mhz CE and 100mhz C/S logic boards side-by-side . . . What differences do you see between the two? And don't say none, that you haven't got the CE board out because .blah, blah blah . . . : >) No good HW hacker is allowed any excuses! Seriously, it ain't that hard to get down to that level of disassembly (as you've discovered of course) and a careful examination of the two LBs may well lead to you to the answer to the question of how to speed up a 100mhz 5300. What makes a CE go 117mhz?!? Hey, and how about a set of closeup pics of both, since yer in there anyway? Hmm, and I wonder . . . is a 1400/117/133/166 603e _processor_ the same footprint as a 5300's? Just some (dopey) thoughts, Dan K (dangit, now I gotta go get a 5300 to play with!)
