What are the Copyright Dates on the PCB and ROM? It will be interesting to compare the dates. My PrecisionColor Pro 24AC is '93 on the PCB and '94 on the ROM, IIRC. Your card looks like it has features of the 24AC and the Thunder IV. I'm too tired to dig out the Thunder IV GX 1600, but I'll guess that the IC with the silver sticker is the 10 bit DAC, it looks like the same IC on the Thunder IV series.

What was the date of that review?

I think the LeMans might have been on the threshold of greatness, better technology than the 24X series, but overshadowed by the later Thunder IV series with oodles more VRAM.

I've got no idea where the 24AC fits in. I snagged a pic off an eBay auction for a LeMans a while back, now I wish I'd bid on it. :-/
