Well, the stickers on the top of the soldered in chips say:
[341S0827 916] and [341S0871 919]
Not sure how via software to get info about the ROM version -- perhaps someone could tell me if there is a way? Also, is there any way to have the system report how much VRAM is installed? I could have sworn with all 6 sticks I could get color modes above 256 color with the on-board video. And now that I've pulled and put them back in it seems 256 is the top. Maybe I'm just confusing with the RADIUS card that was installed -- I've been fiddling so much I've lost track now.
