UMax SuperMac C500 CPU 603e 180 MHz
Part#910252-11 SSCPU
The seller has several BGA versions, but I snagged the only QFP INSIDE UMax CPU Card he had. [

IIRC, all the 1400 cards, with the exception of the slowest, used a BGA package 603e.
The reason the mysterious DuoHacker never attempted this graft was that he couldn't locate the four resistors normally used to determine the clock speed. I never tried . . . hence . . .
. . . the neolithic, brute force approach I plan on using for testing! }
edit: now that I think of it, I should try to find the PowerDuo parallels for the resistors TomLee posted for the 5300!

AFAIK, the 1400's 117MHz CPU Card's QFP 603e should work for this hack too! [I'd love to see the 2300c with just a little more boost - 117Mhz, 133 even
