Joli clavier
HiTek Stackpoles are usually disliked from what I seem to read, but this is a nice collection piece.
I saw some french so I had to do some digging to figure out what these were used for. I had a lot of trouble finding "TIJ", but it seems to have been renamed to Proxes France since then, or at least I think. I dug some more and found this company was created in 1984 ... huh '84 ? I read that somewhere ... and in fact, the date of creation of Proxes and the "Nr." written on this board are very close ! The 23th week of 1984 is July 2nd to July 8th and the creation of Proxes dates July 24th of 1984. So I bet this keyboard was one of the very first equipment this company ever bought ! Not really interesting of relevant, but I think this is a neat historic anecdote that may make this keyboard a little more special
edit : I forgot to mention, but Proxes seems to deal in wholesaling of machine tools.
