    California WTB: QFP 68030-25

    I'm after an SMT 68030. Must be at least 25 mhz, can still be attached to a junk board. I already have through-hole 030s of varying speeds, this is needed to resurrect a system. The situation with fakes on eBay and UTSource for these chips is catastrophic. It is now impossible to source one...
