Takes nothing more than a 74LS147 and some pull up resistors
on the inputs and inverters (or open collector transistors with
pull ups) on the outputs.  The Orion II band outputs are open
collector - maximum pull-up current is specified in the Orion II
manual.

Everything you need to know to roll your own is in the 74LS147
data sheet.

73,
