89C668 will not run

[ebarker]

I have a simple 89C668 project that runs great on a Nohau emulator.

I can remove the emulator, and install the processor, then run FlashMagic and it does a great job or so it seems of programming the part.

But the chip will not run after programming.

Nohau works great.
FlashMagic works great.
Boot Vector is 0xFC, status byte is 0x00
Board doesn't run,

Any ideas ?
