	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.
						Thank You
