Egyptian Enterprise 64 number 2

OK, so the L2 mod simply provides a stable 14Mhz clock to Nick as it would seem the circuit that generates it gets unstable over the years.

Could I simply use one of the clock outputs on one of my clock boards to replace this?

More thinking required

I haven't been able to get a login on that forum so I can't see the pictures or download the schematics/diagrams in the thread I referenced for "The L2" fix.

So here's the thing, I've been able to get on and frankly there isn't much to see.

Essentially the OP stated that whilst adjusting L2 on their machine the core broke and a replacement adjustable inductor couldn't be found.

Basically he removed this part of the circuit entirely from his machine as it wasn't working:

And replaced it with an oscillator that generates the 14Mhz clock that goes to Nick. I could do that with my clock replacement board, however I may consider seeing if L2 on this machine can be adjusted with the correct tool and that may be enough to change the shimmer.
