The video card says raster ops for II portrait display. The portrait display is black and white and when I open the monitor control panel it says its goes 4 shades under black and white and 4 in color. There are some open chip slots on the card but the monitor is black and white so no need to mess with it. Has a cache card in it. Boots fast under 7.1 8 Meg's of ram but hard drive was dead had a spare of course. Also has Ethernet card so that's cool. Volume is great no leakage I can see on the board, o e question tho where is the pram battery? Is it under the power supply or the floppy?
