That's very satisfying to hear, thanks!
Glad to hear that it's still rockin' strong like we intended.
That's a respectable track record of reliability so far.
We see them occasionally come in for Z4 upgrades as far back as the early 1994-95 with the datawheels up on top.
By the time your ZX was made we pretty much had the manufacturing down cold, and yes, I still test every single one myself like Dr. Bob Moog told me to in 1997. I remember that highlight like it was yesterday.
