Seriously, a Mini Palette with one screen, not a Mini Light Palette with two screens? If so you were one of the few!
We had 3 in town, the first in 1973, the second approximately three years later when our convention centre was added next door and the third in our local Catholic Basilica where it controlled a first generation CD80AE rack with two wall stations controlling the rack six days per week and for cleaning lights plus a portable wall station which could be located in the middle of the church to program new scenes directly into the CD80AE for special services.
Yes, an original 'one-eyed' Mini Palette with a white desktop case and outputting AMX.
Remember it well, with its Fred Flintstone wheel.First console I ever used was ETC's Microvision FX (without a reliably functioning FX section). If I recall correctly, it had a 3 digit serial number and had a 1992 or 1993 date on it. I first used it in 2004 and got the high school to replace it with an Express 24/48 a few months before I graduated.
