For anyone that needs (or may need someday) a CPU chip (MC68EZ328) for the
Orion 1 main board, I ran across this ebay seller. According to the schematic,
the MC68EZ328 is what is used on that board. I believe it is a 16MHz CPU.
Only $10 shipped, cheap insurance.
Another Orion user said his chip was stamped XLINK 68328, so the part numbers
seem to be consistent.
The Orion 2 uses a similar chip but running at a higher clock rate.
It is a surface mount device so you would need someone skilled to replace it.
