Charger Specs for Rockwell 74k Calculator

[rprosperi]

Thanks Dieter and Zaphod. As noted, I did initially presume it was meant to run the machine without batteries, however the 74k machine (or at least the sample I have) has a 3xAAA battery pack soldered into the case, so it didn't seem to make sense, unless of course this term was widely used to simply mean running the device directly from the adapter (e.g. if batteries were dead).

Anyhow, while the term itself is not new to me, this form of usage is. If this was common in UK (presumably in the 70's at least), is it still widely used? For example would a current mobile phone's power adapter have the name Eliminator on it, or would a random millennial walking the streets of London know this name?

Also, does the 24k model have a removable battery?
