You're brave to do this without even a logic probe. :) You could use almost any parallel EEPROM for the hex display decoder. It's difficult to find ones that don't have vastly more memory than is required. The extra space can be used to provide more features. For instance, I designed a four-digit decoder that has hex, decimal, signed decimal, and octal display modes using an AT28C64B (and that only uses half the available space). Great work!
