PIO-96 User’s Manual
The four 8255 PPI components are in sockets. If any of the digital I/O chips are damaged by
external shorts or transients, replacing the appropriate chip may correct the problem. The 8255
chips on the PIO-96 board should be replaced with an Intel P8255A-5 chip or equivalent part
from another manufacturer. Nothing more than a screwdriver is needed to make these repairs.
