Current State of Datanetics Layout<\/p><\/div>\n

I’ve got all connections made, except for the connections from the blank keys to the matrix on the upper left side of the keyboard. From here I may take a break and make a schematic, since I’m not aware of any in existence for this keyboard.<\/p>\n

I still have holes to drill \ud83d\ude42 and plenty of fine tuning to do. This layout will match a Rev B board. There is a mistake in the original layout of this board which requires a couple of of cuts and and a jumper. I will probably leave the mistake in place.<\/p>\n

The pinout of the edge connector is:<\/p>\n

Front (from inside of board moving toward edge when facing front of board, left to right)
\n-12V
\nB6 (B is data bit)
\nB5
\nB4
\nB1
\nB2
\nB3
\nReset key pin 1
\nReset key pin 2
\nOutput enable (this is an input to the keyboard, but is pulled up on the board to +5 volts)
\nSTROBE (output)
\nB7
\nB8
\nB9
\nGROUND<\/p>\n

back side of keyboard (from edge of board moving inward when facing back of board) (Right to left)
\nblank keyswitch 2-2
\nblank keyswitch 2-1
\nblank keyswitch 1-2
\nblank keyswitch 1-1
\nblank keyswitch 3-2
\nblank keyswitch 3-1
\nblank keyswitch 4-2
\nblank keyswitch 4-1
