[GreenKeys] Manual issue

[Telegrapher@worldnet.att.net]

Folks, let me make some clarifications and additions to this offer.

First of all lets look at the KSR.  Most common manuals for this unit
would be for the Printer and keyboard.  Wiring diagrams esentially
involve the stuntbox, selector magnets on the printer and the contact
box on the keyboard base.  Lights on the cabinet are a function of 1:
end of line on the printer, normally set for 72 spaces although it can
be adjusted for other numbers, and other functions which would have been
dependant on what type of service the unit was originally configured
for.  These functions would more than likely have all been tied in thru
the terminal strip on the back of the cabinet (inside).  What changes
would have been made are again dependant on prior owners making the
thing work.  I haveno diagrams for that!.  The printers are basically
all the same.  Variations will depend on the stuntbox arrangement
mostly.  Unless you've got a stuntbox full of code bars etc, knowing the
model number like 28D, 28H etc will allow me to provide at least some
sort of wiring info.

Keyboard bases are again pretty well the same.  There can and are i'm
sure variations as to how they were supplied depending on their useage
and system they interfaced with.  

For manual purposes i can supply copies of:

28 Printers:	Description and Operation
		Adjustments and Lubrication
		28 Typing Unit Parts

28 Stuntbox	Description and Operating Principles
		Installation of Function parts on a 28 Stuntbox

28 Teletypewriter Base (KSR) Description and Principles of Operation
28 Teletypewriter Base (KSR) wiring diagrams for 28B, 28C, 28D, 28G,
28H, J, 		K and L bases
28 Teletypewriter Base (KSR) Reqirements and Adjustments

The above are really the integral parts for the ASR as well. 
Differences would be to add the Transmitter-Distributer (for sending
tape), a reperf (if your ASR is equipped so) and a Perforator for
punching tape from the keyboard.  When you figure 2-4 manuals per item
the $ sign gets bigger.  

What i'm asking you to do is figure out what you need for your
particular machine before telling me "i have an ASR and a KSR" and need
manuals.  You could be looking at 3-4 inches worth of paper and several
hundred pages.

I'd really like to have the numbers from the Printer, Keyboard Base,
Perforator, Transmitter-Distributer and if you have a reperf, that as
well,  It would be like a 28D printer which would be located on the
front -right side of the printer (on the "front plate"), and on the left
side-top of the keyboard base.  I know they are on the T-D and Perf
units but not sure just where as i don't have those units.  

Next part of this is, what manuals do you want for each unit? There is a
Description and operating principles, Requirements and Adjustments,
Lubrication, a Disassembly and Reassembly and finally Parts.  

Normally you wouldn't need a Parts manual.  If your not mechanically
inclined and the machine is running smooth and fairly quiet (as much as
can be) there is no reason for a Requiremtnts and Adjustment book.  You
need specific tools such as all kinds of gages and spring tension gages,
a couple of clips, spring hooks for pulling and puching springs into
position.  A word of caution, Springs have a habit of jumping off their
connection points and into the VOID.  take care when playing around with
your machine, especially if using a rag to wipe oil, grease or dirt/dust
off of something. I don't recommend trying to "randomly" trying to
adjust something to fix a problem that you don't know technically
exists.  Ask the list about the problem.  I suspect between some of the
Ex-TTY repair people on the list you'll get an answer as to what action
to take.

In the end, it looks like what you all would be intersted in is simply
the Description and operating Principles manual for whatever item(s) you
have.  Save yourself some money and useage of paper that may just end up
in the trash.

I've considered doing some printer maintenance here.  I think that
unless you were local the cost of shipping it back and forth along with
my time/labor and any parts might become prohibitive for most all.  I
have no way to clean the machines easily.  A way to insure your machine
is kept in top shape is to keep it clean inside the cabinet, insure the
felts and areas where moveable parts make contact are lubricated
properly.  Don't over oil nor over grease. Try to use materials that
will do the job adequately.  Remember that these machines were built for
24 hour a day, 7 day a week operation and your only gonna use yours for
probably less than 10-15 % or that period of time.  A well adjusted,
clean machine will work for years without ever having to be touched.  

I'd like comments about this dissertation (sp).  If you want manuals,
let me know what it is you have and what you really need for your
situation.  I'll get you a price for what you want.  Hope this has
pretty well covered this topic.  I am by no means an expert on this
subject, just someone who went to Bell system 28 School back in the 70s
and spent several years doing maintenance on the machines.  Jack and
others on the list have far more experience than I.  But i bet we all
agree on the general info i've stated here today.
