BCD Converter


The BCD Conversion Module is an I/O module that enables 620 CPMs to convert BCD numbers to a binary format, and binary numbers to BCD.
This module contains a total of eight 16-bit addressable registers that store data to be converted. The higher four addresses convert BCD data to binary. The lower four addresses convert binary data to BCD.
The frontplate of the module is permanently attached and includes one green ACTIVE LED, which lights when the module is being accessed.
