At all this price crazyness, ive seen and missed (because of unavailability to

CD11 for like 30$, and a Pandicon ZM1200 for 150€, so the cheap ones are still

I have one with the keyboard and the spark erosion printer. It uses a core plane non-volatile memory. If you programmed a lengthy calculation, you could just switch it off at the end of the work day. The next day when you turned it back on a red lamp indicating that it was still calculating

Here's an Instagram post of a "Penning Trap". I guess the same Penning
we know from the Penning mixture in gas discharge tubes.
The Penning trap was not invented by him but was named after him by the
inventor. See

There is an error on the page that I noticed. The ZM1020 label is incorrect
based on the tube shown. It should be ZM1210. ZM1020's (and ZM1022's) are
round end-view tubes that are the same as the QS30-1 (except the ZM's have
mercury in them).
