A framebuffer. But why four DACs? The framebuffer itself is the 72 16kbit DRAM chips. Slightly more than one megabit. Not much being a color framebuffer. I wonder what the colordepth and resolution was on this one. 256 x 192 and 8 bits per colour perhaps? Anything else known about it except for what Lyle dug out?
