Dear List!I do not think it will work just by changing plugs. It is not going
Recently I've found a nice old computer. It's called Convergent
Technology. Some 80's machine without any decoration signs. The problem
is I have only box with motherboard and processor and a keyboard - no
display. The display was main link between keyboard and box. So, I can't
run it. What I actually want to do, is to use its keyboard on my modern
computer (Celeron 510 MHz with 256 MB memory running FC 7). The
keyboard has some strange plug. It looks like network (LAN) plug, but
board. Pictures of the keyboard and plug can be found at the address:

If I'll solder a PS or PS/2 plug to it is it possible to run this old
beauty? I vainly googled for the information about old keyboards. And
found only stuff of how to make a valet from it.
Thanks for attention,
Hiisi
to have the correct scan codes. If it is what I think it is, the
"monitor" was actually a terminal. The machine you have probably
used a serial connection to the terminal, and the terminal send
ASCII code to the computer. If you had the "CRT" part, you could
probably hook it to a serial port and use it under Linux. (I have
done that with a few "smart" terminals...)
The keyboard may generate modified ASCII code, or its own codes that
the firmware in the terminal translated. A common method was serial
communication with 7 bit ASCII code, and special functions if the
8th bit was set.
What you MAY be able to do is convert the keyboard so it will
connect to a serial port. But it is probably going to be more
trouble then it is worth.
