[GreenKeys] It's a KSR, not an RO after all ! !

[Don Robert House]

Larry,

I have been looking for an example of the 43A Carrier unit for about  
20 years.  I have a couple of questions for you.
Is the typing unit sprocket feed?  Did the machine come with a paper  
box for the fan-fold paper?
Is the typing unit platen standard width?  Does the typing unit have  
vertical and horizontal tabs?

What you might have is an airline tele-ticketing machine.  The  
airlines had them made all the same... KSRs
If the particular location had no need for the keyboard it was  
covered.  The good news was that come time to troubleshoot the machine
The repairman could use the keyboard.

I would appreciate some images if you get the time.

Best,
Don

Howdy guys,

This tty I picked up today has a 83B2 selective calling unit and a  
type 43 carrier receiver.

I thought it was originally a 28 RO but, has a plastic cover over the  
keyboard to cover the keys and thus it becomes a RO !!  Never saw that  
before.

The base is loaded with power supplies, WECo rack mount type. Multiple  
chassis with tubes and other equipment.

It's totally documented with blue prints and prints for the stunt box  
and, I guess Answer Back.  On the left side below the paper crank  
handle, there is a large magnet operated lever....I'm wondering if  
this was an automatic carriage return, line feed option.

The machine is dirty but definitely very restorable shape.  The  
electrical control chassis is unusual looking too....it has a PC card  
stuck in a socket on the right side.  There's a lot of stunt box  
options...all shown in the drawings...just gotta figure out the Bell  
System lingo.

It was in service from '69 to about '76.  Has all the service cards  
showing the tech's work on it.  The fellow that put it on Craigs did a  
good thing by saving this old beast...I guess Bell walked away from  
it ! !

Just gotta replace the glass window, red jewles for EOL etc.  The  
cabinet was taken care of but, strangely, on the right side, a hole  
was cut into the cabinet and a 4 inch muffin fan  
installed...apparently the tubes in the base caused her to run hot.

I'll try to get my son to give me a URL for the pix a little later.   
All in all, snatching it from the grips of the garbage truck's  
compactor arm was well worth the effort.  It'll be a nice running  
machine again...
