Didn't National Semiconductor have a spec sheet for write only memory back in the late 70s or early 80s? I think they developed it for the NSA. --On Thursday, 23 May 2002 14:53 -0700 Dan Hollis <goemon@anime.net> wrote:

In a silly and useless off topic thread ... I found the reference. It was Signetics, not NS. http://sunsite.informatik.rwth-aachen.de/jargon300/write-onlymemory.html write-only memory: n. The obvious antonym to `read-only memory'. Out of frustration with the long and seemingly useless chain of approvals required of component specifications, during which no actual checking seemed to occur, an engineer at Signetics once created a specification for a write-only memory and included it with a bunch of other specifications to be approved. This inclusion came to the attention of Signetics management only when regular customers started calling and asking for pricing information. Signetics published a corrected edition of the data book and requested the return of the `erroneous' ones. Later, around 1974, Signetics bought a double-page spread in "Electronics" magazine's April issue and used the spec as an April Fools' Day joke. Instead of the more conventional characteristic curves, the 25120 "fully encoded, 9046 x N, Random Access, write-only-memory" data sheet included diagrams of "bit capacity vs. Temp.", "Iff vs. Vff", "Number of pins remaining vs. number of socket insertions", and "AQL vs. selling price". The 25120 required a 6.3 VAC VFF supply, a +10V VCC, and VDD of 0V, +/- 2%. --On Friday, 24 May 2002 04:50 +0000 "Joseph T. Klein" <jtk@titania.net> wrote:

Not long ago I finished reading one of Stephen R. Donaldson's "The Gap" series (the second -- I don't know if I'll bother with more of them) where secure write-only "core" is said to be the foundation for interstellar security. Basically it's for keeping an unbreakable and unmodifiable record of all ship functions and communications. Only authorised police have keys to read it, but it supposed to be physically unalterable once written. Of course it turns out what's written to it is not quite so indelible as most people are lead to believe.... :-) -- Greg A.

Not exactly. As I recall, National or maybe Signetics had a run of FUBAR chips. So they gave them xxxNFG part numbers, and had a data sheet made for "Write Only Memory". The AN showed it being used as an electronic bitbucket, etc. This was in 1971 or 72. If you ordered the data sheet/sample; you likely also got a set of Groucho glasses so "you can sneak into the office even if your colleagues find out".... A friend has the data sheet, and maybe still the glasses/nose. -- A host is a host from coast to coast.................wb8foz@nrk.com & no one will talk to a host that's close........[v].(301) 56-LINUX Unless the host (that isn't close).........................pob 1433 is busy, hung or dead....................................20915-1433
They did but when you mentioned this I went to look for it and haven't found it. . As I recall this was infact for the nsa but I don't remember the exact application. On Fri, 24 May 2002, Joseph T. Klein wrote:
