Hi!
I just succesfully transmitted a few bytes across the joystick network
cable. As promised, the sources are in this mail.
Final bug was removed just 15 minutes ago, so don't expect optimized code ;)
There is still a weak point in the protocol I used. It can cause trouble if
you send one
that guy called
Murphy who made this up?

This however is very dangerous. Since there are two female
connectors on the cable, which both can be plugged into the
MSX, you will have the risk that people will plug the wrong
one in
Hi there,
No, No, NO! This will (for me) not do. In order to make this thing
really "plug 'n play", one connector side should be male and one
connector side should be female. In this way even 'newbies' could plug
in easily to this new network.

You are right. Most people only have 1 MSX computer. However, the big fun of

We could also consider DIN5. That's the one used for audio and for MIDI, so
it's probably more available.

Hi all,
There is also one thing I want to set straight. The connector I mean
isn't a jack (which only has three 'pins'). I meant a connector used
to connect professional microphones. It looks a bit like this (not
that it matters any more ;-) ):
