No sh*t! There are however plenty of computer tubes
around, the 5xxx and
6xxx series. Since the clock is slow I chose high-speed dekatrons to
generate the 20 bit times (bit0 - bit 17, dead0, dead1), and clock and
memory busses would probably require some 6L6's as cathode followers,
6L6s may give you prolems - they are not computer rated (although for a
clock, it should not be a problem). 6005s (computer 6AQ5) is a good choice.
Cheap, too.
