[TenTec] Dragonball CPU for Ten-Tec Orion

[Jeff (W4DD)]

If the CPU is the MC68EZ328 (Motorola), I believe it is the 3.3V supply.  I
bought a couple last year from the seller on ebay and it looks to be an
exact replacement although I haven't had a need to try one yet.

If anyone has success in replacing one and getting a CPU board running
again, that would be an interesting thing to know.

BTW, if anyone has worked on an Orion which reports higher SWR than is
actually present, I would like to compare notes.

GL,
Jeff W4DD

You need to make sure you get the 3.3V version of the CPU.

The Orion II uses the MC68SZ328 (also 3.3V version)
