I am working on a z80 breadboard, and I would like to implement a video display for it. I dug up an old IBM PC mono monitor, the ones the original IBM PC's came with. As the 8088 and Z80's are similar, I would like to use a graphics card to use the monitor. However, I do not understand the relationship between the cpu and the graphics card, which does what, what the graphics card is capable of, and so on. I hear that I can get a monochrome card pretty cheaply for an XT bus. I would be grateful to receive the pinouts of the XT bus, and technical information on how to control a graphics card. I have never owned an IBM PC or gotten intiminate with them, so I'm afraid I may appear ignorant in some respects. I would be happy if that is corrected :-). Much thanks, Derrick
