TTL Data Book, 2nd edition, 3rd printing...

[Joe Gwinn]

At the town dump I found an almost pristine copy of the Texas
Instruments \"TTL Data Book for Design Engineers\", second edition,
third printing, copyright 1981, 9.5 inches tall by 6.625 inches wide
by about 1.5 inches thick, and 2.5 pounds.

The book was in with children\'s books (huh?), so nobody had noticed
it.

Is anyone interested?

If not, back to the dump it will go, but in the technical books area.

Wow, the dump has a special place for technical books (vs. children\'s books)?

The dump, here, separates out major appliances (as they can have significant
materials reclaimed from them with minimal effort) and \"everything else\".

here there is many more categories; cardboard,paper,wood,plastic, glass,metals,electronics,furniture, building materials,garden waste, hazards materials, reusable clothes, recyclable clothes, probably a few more and the \"the rest\"

Is there a scan of it on Archive.org? If not, you should donate it to someone like Bitsavers to scan and unload it.

A classic....The first edition provided endless hrs of reading on my Senior EE Advanced Computer Arch class....we designed a 8 bit ALU.
Thank you for sharing

Same here.

Any reclaimable value in \"discards\" is typically intercepted before a
\"trip to the dump\".

The city collects glass, certain plastics, tin cans (but not aluminum!),
paper (e.g., junk mail), newspaper and \"hazardous waste\" separately
from regular trash.

[Hazardous waste includes electronics!]

Construction materials must be delivered to a different dump. Ditto
fill (clean and otherwise). And yard waste.

And, the rules for homeowners are far more tolerant than for businesses
(though I\'m not sure how they know if Bob\'s pickup is a business vehicle
unless they recognize him as a frequent visitor? \"Gee, Bob, just how big
*is* that HOUSE of yours that you have all this waste???\")

But, it still relies on individuals to do the sorting and impose
self-discipline in their disposition of those items.

[E.g., we don\'t recycle glass because it has to be washed to be
free of any residue (really? the city can\'t do that /en masse/?)
and it has to be driven to a special dropoff location. We\'re not
going to stockpile glass bottles for a month or more just so we have
enough to justify a trip to said dropoff! (the city used to allow
us to recycle glass at curbside. A friend discards a case or two
of wine and beer bottles each week out of disdain for this change)
Isn\'t this just another example of how \"productivity\" has been
improving... by shifting the costs onto the customers??]

Most non-businesses have no need to visit the dump. We have twice annual
\"brush and bulky\" pickups where just about anything you want to discard can
be placed on the curb -- furniture, appliances, tires, (massive amounts of)
yard waste, etc.

The city is divided into ~25 regions and THE crew services one region at a time
for a 5 day period (it takes that long to capture all of the discards based
on type of material). You are *requested* to sort your items into different
piles to make it easier/quicker for the crews to \"claim\" them. E.g., if you
trimmed a tree, pile the branches (in 4ft lengths) in one spot along your
curb, separate from that sofa you wanted to discard, etc.

[The crew shows up with lots of heavy equipment brought in on a flatbed
(along with a port-a-potty). So, a guy will scoop up all of the brush and
dump it in a dumptruck and then both will move on to the next house
while a workerbee cleans up any residue left on your \"lawn\". Things that
really *need* to be boxed (e.g., cactus trimmings) are expected to be
in appropriate sized boxes with weights not to exceed 70? pounds -- which
is pretty easy with cactus! If you fail to follow the rules, the items
will be left on the curb -- and your neighbors can then formally complain to
the city, leading to a fine.]

If you have a landscaper, part of your fee will likely be his cost of carting
your yard waste to the dump -- and, if he is doing that for a living, it is
all but certain that he will be recognized as being a business user (along
with the shitty pickup truck he will be driving!)

Construction/remodeling crews will similarly haul off the waste created
in the course of their activities.

Have a water heater replaced and the plumber will haul your old one off.
Ditto if you purchase new appliances, bedding, etc.

So, there\'s rarely a need for an individual/homeowner to visit the dump
(I\'ve been exactly once in ~30 years -- when *I* broke up the concrete
sidewalk leading to our door and had to dispose of the \"urbanite\")

also lets them keep track of how many times people have been there, and in
some place check if you live in the area

The city\'s recycling center queries drivers for their ZIP code -- but only
to get an idea for where folks are coming from (the drop off site
varies from month to month; if you show up at a site far from your
ZIP code, that lets them know that they may need to increase the frequency
of drop-off events in YOUR area). Anyone can drop off goods anywhere.

[The city encourages this as the alternative is illegal dumping...
folks discarding items in washes, empty lots, etc.]

But, it still relies on individuals to do the sorting and impose
self-discipline in their disposition of those items.

here everything must be in clear bags and the people working there can get pretty grumpy
if you are being stupid

Our curbside recycling is just everything in one large (85G) container
picked up every two weeks (used to be weekly but I suspect too many
homes couldn\'t fill the container in that short a timeframe).

Hazardous waste recycling is usually large enough items that one wouldn\'t
box/bag them -- computers, buckets of paint, antifreeze, EMPTY paint
buckets, etc.

On visiting the dump, depends on where you live. We have family and friends a hour north of Boston. In that area, everyone visited the dump. A Saturday ritual was to load the trash in your vehicle and go to the dump. It has a number of areas - general garbage to be compacted, a shed loosely divided into some areas that have tables & shelves for: kitchen & household (small) appliances, electronic \'stuff\', childrens things (toys etc.), and books (all kinds). The early to mid 90s was a rather good time to pick up \'old\' PCs & parts, printers, old Macs, etc. Most of the time the electronic stuff we picked either worked and had minor issues.
Haven\'t been there in 10+ years but I understand it is still the same.
The dump serviced a number of townships around the area.

\"Stockbridge, Massachusetts\"? :>

Did they not have curbside pickup of regular trash? Everywhere I have lived
has had at least a weekly \"trash pickup\" at your home. In the 60\'s, recycling
meant a trip to a central facility where *you* had presorted your glass
(green, clear, brown), newspaper, cardboard, aluminum, etc.

But, as recycling became more mainstream, every place has had that at
curbside, as well. (Here, we used to be able to leave motor oil in a jug,
at the curb; the truck\'s operator would empty your container into a
container on the truck. As a kid, the factory where my folks worked
would burn it in their heat-treatment forge)

We always had the equivalent of \"brush and bulky\" for oversized items.
But, AFAICT, it was a random event (as a kid, I had no real interest
in figuring out when such events were *scheduled*). So, you might
have to hold onto something for a while that you really wanted to
discard *today*.

[One can have the city come out to pick up such items, here, at any
time. But, there is a special fee assessed as it\'s not part of the
normally scheduled service (paid for by your trash fee)]

It has a number of areas - general garbage to be compacted, a shed loosely
divided into some areas that have tables & shelves for: kitchen & household
(small) appliances, electronic \'stuff\', childrens things (toys etc.),
and books (all kinds). The early to mid 90s was a rather good time to pick

electronic stuff we picked either worked and had minor issues. Haven\'t been
there in 10+ years but I understand it is still the same. The dump serviced
a number of townships around the area.

As a kid (CT), I don\'t think I ever visited The Town Dump. It was located
behind the incinerator (burn the trash). I recall a big fiasco, at one time,
regarding pot plants being found growing at the dump. Morons couldn\'t
recognize the difference between a marijuana leaf and a TOMATO leaf!
<rolls eyes>

Here, there are lots of \"thrift stores\" that will accept \"donations\".
They will try to resell these (with minimal refurbishing) to the public.
Some are operated by non-profits and get some of their operating
funds, this way. Others are actually *businesses* eeking out a profit
from goods obtained for $0.

[I hunt for old bits of pyrex kitchenware in such places]

E.g., when local recycling groups started charging to dispose of CRT
monitors/TVs (typ $25), folks-in-the-know would drop off their \"tube TVs\"
at Goodwill and let it be THEIR problem! (they might find a buyer).
I.e. if you are discarding something that has some residual life (or
LOOKS like it has), then you could drop it off at any number of such
places (I can probably find a dozen in a 10-minute drive from here)

There are other groups who accept items to recycle to keep them out of
landfills and/or reintroduce them into use (reuse-refurbish-recycle).
Again, anything that looks like it still has useful life can likely
find a new home for low dollars (no goods acquisition cost, no labor
cost -- just recover something for the rent/utilities).

[I\'ve spent more than a decade with one such group reintroducing
discarded desktops/laptops to underprivileged clients along with
medical supplies and DME. We recycle school textbooks to teachers
around the country. At one point, we even offered \"upscale\" clothing
to folks going on interviews, fresh out of prison, etc.]

OTOH, there are far more groups who *generate* this sort of trash.
Businesses in PC upgrade cycles dump thousands of WORKING computers
each year. We had one national chain who would truck the equipment
from all of their stores, nationwide, here for us to \"process\".
Imagine emptying a semi filled with electronic kit. Every month or two.

Local businesses have regular auctions as they try to (or must, by law)
recover whatever they can from their \"scrap\". (I filled an SUV for $74,
including front and back seats!)

Discouraging to see the amount of stuff we discard for no *real* reason
(MS decided to release a new OS??)

Don, you should write a book. Or maybe several books. You know, to let
off some steam or something. Sort of like you do here.

No \"steam\", just recounting anecdotes. And, highlighting things that
are likely \"available\" in other municipalities if folks only knew
where to look.

E.g., the local university has had public auctions... forever!
Yet, until someone TELLS you about them, you\'d never know they
were happening (no advertising involved other than a sign on the
building in which they are held).

Likely folks never considered where all of the \"old\" equipment from
their firms, local businesses, etc. goes. Surely it isn\'t just
discarded!? I\'ve \"discards\" from Burr-Brown, TI, etc. local
offices. Sometimes it\'s just fun to see what they were using!
\"Gee, I wonder what this is a prototype of?\"

I actually find auctions and the like very entertaining; you never
know what you will find. Sort of like walking through an old-fashioned
hardware store (before they started selling kitchen appliances, bbq
grills, etc.).

And, because you likely don\'t *need* any of the things that you come across,
there\'s no pressure to \"win\" a bid. (there are many people who frequent
these things to acquire items to resell so they need to know the actual
values of items and the size of their potential markets)

[There was a precision GPS unit amongst the items in my last won lot...
the sort of thing that a surveyor uses in the field to get precise 3D
coordinates of spots on the globe (50cm accuracy). Interesting to explore.
But, right back into the discard pile (no personal need for anything like
that) and the emphasis, of late, is on downsizing!]

I figure if folks don\'t like my posts, they can simply not click on them! :>
