scratch monkey

(humour)As in "Before testing or reconfiguring, always mounta scratch monkey", a proverb used to advise caution whendealing with irreplaceable data or devices. Used to refer toany scratch volume hooked to a computer during any riskyoperation as a replacement for some precious resource or datathat might otherwise get trashed.

This term preserves the memory of Mabel, the Swimming WonderMonkey, star of a biological research program at theUniversity of Toronto. Mabel was not (so the legend goes)your ordinary monkey; the university had spent years teachingher how to swim, breathing through a regulator, in order tostudy the effects of different gas mixtures on her physiology.Mabel suffered an untimely demise one day when a DEC engineertroubleshooting a crash on the program's VAX inadvertentlyinterfered with some custom hardware that was wired to Mabel.

It is reported that, after calming down an understandablyirate customer sufficiently to ascertain the facts of thematter, a DEC troubleshooter called up the field circusmanager responsible and asked him sweetly, "Can you swim?"

Not all the consequences to humans were so amusing; the sysopof the machine in question was nearly thrown in jail at thebehest of certain clueless droids at the local "humane"society. The moral is clear: When in doubt, always mount ascratch monkey.

ESR notes: There is a version of this story, complete withreported dialogue between one of the project people and DECfield service, that has been circulating on Internet since1986. It is hilarious and mythic, but gets some facts wrong.For example, it reports the machine as a PDP-11 and allegesthat Mabel's demise occurred when DEC PMed the machine.Earlier versions of this entry were based on that story; thisone has been corrected from an interview with the haplesssysop.

A corespondent adds: The details you give are somewhatconsistent with the version I recall from the Digital "WarStories" notesfile, but the name "Mabel" and the swimming bitwere not mentioned, IIRC. Also, there's a very detailed account thatclaims that three monkies died in the incident, not just one.I believe Eric Postpischil wrote the original story at DEC, sohis coming back with a different version leads me to wonderwhether there ever was a real Scratch Monkey incident.
