does anyone have any information about programming the serial ports on the rainbow 100 from CP/M?? more specifically, i'd like to write some assembly language stuff to control the ports. also, how do you write directly to video ram from the z80?? -- fzsitvay@techbook.COM - but don't quote me on that.... No wonder I can't hold a regular sleeping schedule. My subconcious mind knows we are only one well-placed bullet from having Quayle as president.
