Shepparton TNC 220+ Construction Manual and Schematics - ChickenMan - 25-07-2021
I finally go around to scanning this manual that I was recently given, A4 in size, single sided pages and 67 pages long.
Shepparton TNC 220+ was produced by the Melbourne Packet Radio Group, St Albans, Vic, Australia. It was designed by Mr Ray Gardiner (VK3YNV) from Shepparton, for the development of the Australian Packet Radio Network. As all TNC's come from overseas at present and are expensive, it was decided to produce a local TNC that would allow the Australian Packet Network to be developed under Australian control. To do this it was necessary to have our own hardware and software that could be developed as required and not be forced to use products beyond our control. The price of the TNC could also be kept under control.
The manual, dated 23rd May 1989, not only includes assembly instructions but also the Operation Commands & Instruction set using Pac-Comm ver 1.1.5. Schematics have been included as a separate file as scanned at a higher resolution. Schematics to connect the TNC 200+ to a Premium Microbee are also included.
The files have also been uploaded to archive.org to hopefully reach a wider audience.
So in the MbeeTech Repository in the Documentation/Manuals/Hardware folder we placed
shepparton_tnc_220+_manual.pdf <--- both in the one ZIP file
