    I've always been intrigued with the idea of making a console/serial port compatible DOS where video memory was checked against a copy of it to note what was changed and the appropriate characters were sent to bring a terminal screen up to date.

    Back in the early 80s, a friend and I actually came up with an ISA card that has not only the memory, but a Z80 with DART and peripherals. It allowed for sharing a VT100-ish terminal screen between a MDA video PC and a remote mainframe. Even emulated the XT keyboard from the terminal. Still have the card and the firmware that I wrote.
