I've got a 56 bit (sorry, not byte) core store if you need a memory upgrade.

A 12AX7?

It's a shame, but I lost a two-tube circuit board I once had from a 50's computer - a Bendix I think - with two 6146 beam power tubes, part of the drum memory head driver circuitry. Maybe two in parallel to feed a head? [shades of Gracie Slick...]

What a concept.

More likely a 12AV7 or maybe a 12AZ7.

A "pointed little head"? ;)

None of the above; baseless miniature tubes like those didn't show up until quite a while after the ENIAC was developed.

Most likely it would be a 6SN7, though other octal-based tubes of similar vintage were used too.

Probably. It's definitely octal. No idea if it's original though.
