need help on a key pad matrix

I have a project Z80 mini board one input and one output the input has a 74LS244 which go to the Z80.rom,ram can I connect the key pad matrix to the input will it work or do I need a microcontroller project or project
there is a schematic look at the input port I need to connect a key pad matrix
U3 is 74LS244

this input is from the Z80 mini board not the 74LS244
The input has 10 pin
pin1 5v+
pin2,3,4,5,6,7,8,9 go to the 74LS244
pin10 GND
I have check on the web site and found this IC mm74c922 has any one got a project that will help me connect the key pad matrix to the z80 mini board

pins 2, 4, 6 and 8 are inputs on the 244, pins 3, 5, 7 and 9 are outputs. Check the datasheet for the function of pin 1. The most you will get are 4 switches (unless you do some software magic). E
