[GreenKeys] ASR33

[Jack]

It also helps to put some tape in the perforator and watch the
code bits as you type/send to it. It gives you a quick
idea if the selector and code bars are working.

Also make sure the dashpot is clean as well as the "bearings"
(sideplates) on either side of the platen.

As Wayne rightly says, 33's get gunked up....

Nico,

Most problems on 33's that have been stored a long time are related to
congealed grease.  It can be freed up with some solvent (I use
Breakaway) and then oiled after drying.  Dont spray any solvent near
plastic parts like the answerback contact area or kybd contacts etc.
The codebars that Peter mentioned are usually sluggish with the
congealed grease.  

Does it type letters correctly?

CR is 1348 marking and LF is 24 marking.  You can look at the code
bars on the left side where they extend out from under the tape punch
to check.  Marking codebars will extend out, spacing will not.  #1 is
at the rear of the bars, 8 at the front.  Some machines with ALT kybds
send the 8th pulse all the time.  

Also on 33's, the main rule is VISUAL, VISUAL, VISUAL, right guys?  No
adjustments unless you are sure.  Not too much typing till you check
the rubber hammer or you will ruin the typewheel.  I think thats enuf
for now.  

Have fun!

IIRC there are code levers which move when the CR and LF are present
in 
he individual bars after being converted to parallel.  Check that they

re lubricated and can move freely and that the corresponding
mechanisms 
re the same.  Check also for missing springs.  It's been a long time 
30+ years but that's a good start.

 Hi folks
 I've just laid my dirty hands on an ASR33, destined for our data
museum. 
 Very nice machine, kept in a dry cellar for many years.
 The only problem I've encountered so far, is that neither RETURN nor 
 LINEFEED work. Things move, but the carriage is not returned, and the
paper 
 is not advanced.
 I have only this mmachine at home, so I can't readily compare it to a

 working machine.
 Any help would be appreciated.
 Oh, I have the full documentation, so even references to pages would
be 
 appreciated
 Regards
 Nico (OZ 1 BMC)
