I haven't found the Avelan manual on the internet.
I don't even know what year it was released in, I guess 1981 or 1982.

Anyone knows which is strongest?
- Fidelity CR
- Fidelity ACR
- Borcheck
- Avelan

(it's possible Avelan is the same engine as Borcheck, similar to the Sargon engine being sold on both ARB and GGM)
