RADIX 50[1][2][3] or RAD50[3] (also referred to as RADIX50,[4]RADIX-50[5] or RAD-50), is an uppercase-only character encoding created by Digital Equipment Corporation (DEC) for use on their DECsystem, PDP, and VAX computers.
RADIX 50's 40-character repertoire (050 in octal) can encode six characters plus four additional bits into one 36-bit machine word (PDP-6, PDP-10/DECsystem-10, DECSYSTEM-20), three characters plus two additional bits into one 18-bit word (PDP-9,[2] PDP-15),[6] or three characters into one 16-bit word (PDP-11, VAX).[3]
The actual encoding differs between the 36-bit and 16-bit systems.
