One of the things I've lost over the years is a copy of the SIGNETICS WOM datasheet. I'd like to show this to some co-workers who have never had the chance to marvel at this ingenious part. If someone would take the time to arrange to send me one I would be most gratefull. The last one I saw was a copy of a copy of a copy ... and in pretty bad shape. [Now let's see how many questions this creates] Thanks. Larry Pajakowski 1-312-937-1153 (A.C. 708 after 11/11) larry@tapa.uucp

No offense intended but... I have a Polish Op. Amp. data sheet from Signetics also.

We sold a few I know, but the product it went into never was a hit and so I don't think we make them any more. The strangest thing to me was that it had *seven* pins... P.S. This chip wasn't a joke, but there is a twist.

If the data sheet is pre 1982 (or so), then no offense taken. But geeesh, you guys, come on ! Signetics has done a complete turn around though their "zero defects" program and for the last several years, we have decreased the number of defective units shipped to just a few units per million. By the way, I wouldn't mind having a copy of the data sheet (for my own amusement.

Ahh, now there's an oldie. I believe the first time I saw the infamous WOM data sheet was back in 1976, I think. There were some interesting tidbis: the graph of pins remaining vs. number of times inserted, etc. The WOM had an interesting input: chip destruct, which reqired 115 vac to activate; not exactly a jdec spec input. Seriously though, I've seen the term WOM used to refer to active bus terminations. Bill

OK, I've been forced to get my copy out. It appeared in the April (of course)
1972 (I think - it's Copyright 1972) issue of Electronic Design, Computer
Design, or EDN.
A few tidbits:
Part Number: 25120 Fully Encoded, 9046 X N, Random Access Write-Only-Memory
Applications:
Don't Care Buffer Stores
Post Mortem Memories (Weapon Systems)
Artificial Memory Systems
Overflow Register (Bit Bucket)
Input Protection:
All terminals are provided with slip-on latex protectors for the prevention
of Voltage Destruction. (PILL packaged devices do not require protection).
Cooling:
The 25120 is easily cooled by employment of a six-foot fan, 0.5" from the
package. If the device fails, you have exceeded the ratings. In such cases,
more air is recommended.

I'll tell you when I'm giving you the party line. The rest of the time
it's my very own ravings (accept no substitutes).
