I need to make a keyboard cable for one of my Texas
Instruments Portable Professional Computers. It is a
proprietary format with a standard CPU keyboard
connector on one end and a PS/2 female connector on the
other. I have a keyboard cable from a Texas
Instruments Professional Computer, which has the CPU
connector (and a grid-type plug on the other end) and
is a five wire cable. I had hoped to splice a standard
PS/2 cable onto it, but upon opening one of these up I
see there are only 4 wires so I'm a wire short
Yes, PS/2 only uses 4 wires:
------ 1 Data
/ 5 3 \ 2 (Reserved)
| --- 1 | 3 Signal Ground
| --- 2 | 4 Power +5V
\ 6 4 / 5 Clock
------ 6 (Reserved)
My question is, does anyone know of a PS/2 type cable
that has connections to all 6 wires that I could splice
onto the keyboard cable I have?
Some Sun and SGI cables use five or six. For example, an SGI keyboard
cable for an Indigo uses pins 1-5, and early 4D series use all six. Some
extension cables sold for mice may have more than 4, because some dual
serial/PS2 mice use them.
