ribbon cables with screw-terminal boards to connect the limit (and home)

with all the necessary parts, so you would just follow a script, with a
minimum of choices, to build an RT-Linux system configured for
your computer.
Is anyone interested in such a package? I already have servo boards
designed, as probably everyone know. I also have the 50-pin
screw-terminal boards, which are in use on my system. These can
be seen at http://www.artsci.wustl.edu/~jmelson/EMC.html .
I haven't made a PC board for the E-stop and junction board, but
if there is sufficient interest, I could also do that.
I suppose this could also be set up as a solder-it-yourself kit,
as I did with the servo amps, but I was also thinking about making
a completely assembled kit. You would just have to mount the
several major components, plug in the ribbon cables and then
wire up the motors, encoders, limit switches, etc.

[Yes, this does sound like what I need. I am definitely interested. I think
the servos and amps are still functional, so all I'd need would be EMC -
preferably loaded onto a computer and working, with a CD "rescue disk" as a
backup, a STG board, the Estop board you mention, wires and cables, and
clear instructions as to which wires go where. I'm not interested in
"solder-it-yourself" kits- I'm sure there will be plenty of fun for me just
hooking things up and watching for smoke signals. In fact, I'd be willing
to forgo that dubious pleasure- if anybody wanted to come by and give me a
hand with that, I'd shower them with "green stuff" and even throw in a tour
of Oakland Technical High (bring your own humvee).
Do you think you could give a price breakdown for the items enumerated above?]
