I need any and all information on the I/O ports on the following two computers. Sinclair ZX81(yes they're still around!) It has a port on the back, if any one has information on this computer port and how to access through Sinclair commands please e-mail. TI 99/4A This has a few ports. On the left side there is joystick port, on the back there is a cassete interface port, on the right side there is a port to plug in a hard drive or other peripherals, and on the front there is the slot for TI's game cartridges. I need the I/O signals for this to use it as a center of a project, and possible interface to an IBM PC. As I stated before, I need I/O lines for both of the above computers.
