[GreenKeys] M43 Paper Tape Reader/Punch

[Don Robert House]

>Hello,

>I've recently acquired the subject item and it has a problem

>The ID plate inside the unit indicates that it is indeed an M43
>model number 4350AAA. This model is an 8 level unit and
supports both manual and automatic modes

>Bit 1 and bit 5 never

>even when just advancing the tape or running in local mode.
>I can see the pin punching away whenever the motor runs.

>With that, would anyone happen to have the service/tech

>service manual (like with my asr-33).

>Also, any suggestions as to how to approach getting this
>thing fully operational would be most welcome. Thanks!

Hello Scott,
I have a maintenance manual for your unit but it is in San Diego.
I can loan you the manual, but it will  be January before I am back
there again.
