ISA POST Card

This is my implementation of a standard Port 80h POST Card. It could be useful for PC repairing or troubleshooting.

It uses a binary-to-digital decoders, and not able to display HEX numbers (A-F), instead some figures are displayed. I found the SN75LS47 datasheet useful for decoding these “figures”.
