Hi Unit504, I also have a brent lesuire supreme, no specs sadly and somebody cut the top marquee off mine

I've actally owned 3 of them in the past (long story!), they are beautifully made but REALLY heavy and awkwardly shapped for transport... does yours have a hantrex polo monitor ? or a wells gardiner ??
I'f your looking to get it mame'd up I have mine up and running with win xp, an ati HD4350 and soft15khz.. made it dead easy! msg me if you have any questions i'll try and answer what i can.
