[Amps] Alpha 87A Alpha Max Upgrade

[Jim Brown]

I'm considering the purchase of an 87A that shipped from the factory in 
1993. I suspect that it does not have Alpha Max firmware. Some questions.

1) How big a deal is this?

2) I know that chips must be changed and that firmware must be loaded. 
Are these generally available?

3) Any known issues with doing it now?

Thanks and 73, Jim K9YC
