U15 STB 250-0012-001 - MCA bus interface? Also seen on the single-display ERGO.)

My outline does need some fine tuning. I'm working on it.

As for color capability, I have my doubts that it will do high or true color. The RAMDACs appear to be capable, but I have dim memories of someone telling me that only the ET4000/W32 or W32i chips supported high/true color.

All VRAMs and both RAMDACs are socketed. This card has all its VRAM sockets populated. Were these items intended to be upgradeable?
