I don't use one-shots much myself,  but I do have a couple of those,  both the 
LS and the straight 9602 versions,   maybe one and two of them.  I notice 
that some designers seem to favor those though I'm not familiar enough with 
the details to know just why that is.

Back in '78 when I was messing with that H11 system that at that time had _no_ 
external storage except for paper tape,  the company got a hold of a dual 
cassette drive to evaluate.  I got the job of seeing if I could come up with 
an interface for the '11,  and did get as far as wire-wrapping a board but 
never got the handshaking right and the machine never recognized it.  I 
recall a conversation on the phone,  though,  where this guy at the company 
who'd sent out the drive advised *very* strongly against the '123 parts,  
saying that they had some serious stability issues,  or somesuch.  I do know 
I hardly ever see them used,  with the 96x02s being more common for some 
reason.

I did forget about those.  I also remember seeing them in some databook here, 
though with things in their current state of disarray I wouldn't begin to 
guess which book that was.  I also remember those with some other numbers 
attached,  maybe something like "8T97/8097" perhaps?

I've managed okay with their transistors -- and those numbers seem to make up 
the bulk of my data,  for sure,  as well as a lot of my salvage lately.  The 
chips,  though,  are another matter entirely.

And I haven't really even begun to seriously dig.  There's both a mass of 
stuff in books here that I could just enter some basic info on,  and a whole 
lot more out there on the 'net that I haven't dug into yet -- most of that 
stuff came from one or two sites,  which I stopped using when they started 
"branding" datasheets,  none of which I've uploaded.  I've a couple of others 
to hit for replacements,  and then all of the manufacturer's sites yet.

One guy had a bunch of stuff on a web page a while back and it looked like a 
link to my pages would fit in well,  so I dropped him an email.  The one word 
that stands out in my recollection from his response was "Ambitious!"   :-)

Not that I ever actually started out to try and make this project happen,  
initially.  It was more a matter of getting some data on some parts I 
happened to have around (which is why there are part entries with no data at 
all,  I have 'em and haven't found any yet) and arranging what data I did 
find into a form that I found useful.  I'm glad to see some other folks 
finding it useful as well,  and it looks like more folks are doing so lately,  
particularly since I added the datasheets to the pile since I changed hosts.

More data in whatever form is welcome,  and I'll add it as time permits.
