Using the Intel 8255 PIO .......

Post by lezanderson » 19 Jul 2014 21:31

As some of the MTX forum will have receive 8255s in their goody bag of ICs and perhaps wondering whagt they can be used for:

1) The simpliest option is as three 8 bit paralle I/O ports ( or as an LPT1 printer port )

2) Joystick port controller to read multiple Atari type joysticks

3) PATA IDE Harddrive interface

4) Compact Flash PATA IDE interface

5) Obsolete use : To read keyboard Matrix for old keyboards

60 Custom use ... ??


8255 as CF reader / hardDrive interface :
