JNT = the Joint Network Team, the group set up to research and ultimately implement a UK-wide computer network for research and education, which lives today as JANET. PAD = Packet Assembler / Disassembler – a device used to connect circuit-based computer terminals to a packet-switching network such as … oh, I dunno … the Internet.
In other words, this little gadget – well, I say little, it measures 21 x 27 x 46 cm – was quite important in the history of networking.
It could presumably connect 16 terminals to a network, judging by the connections on the back – plus, which makes it so sweet, in the top left corner, a socket for connecting a cassette facility. Bless! That was the point at which I actually wanted to hug it.
