He didn't say that they used Mercury tanks for the delay lines, and
neither the PB-250 nor the IBM 2260[1] did.

[1] Actually, the memory was on control unit to which the 2260
displays were attached, as I recall.

In the early 1950s, what other random-access mass storage was available?

| Those were not used for mass storage.

No-one said they were.

That was to provide an idea of their relative capacities.

You have no idea what the issue im dispute was,

I have, several times, told you what the issue was.

Don't need to. I have read the original paper publication.

You're lying again. In
<4bba8bf1$0$56418$c30e37c6(a)exi-reader.telstra.net> you challenged the
statement

Important numerical libraries were first
| implemented in ALgol,

*THAT* is the issue under dispute, and you keep trying to pretend that
it is something else.

>Don't need to. I have read the original paper publication.

Then why did you lie about the language used?
