ADM-3A Operator's Manual

My copy of this manual appears to be a photocopy supplied by Penny & Giles Data Recorders Limited, in their cover, so I have no idea what the original cover looked like. Some of the pictures haven't reproduced well, but they are as good as the photocopy.

This book is not currently available as HTML, but you can download it as a PDF file (1.8 MiB).

Thanks to Steve Graham for digging out this manual.
