Seems not compatible to me for pins 8-3 are not used.

Correct. You can also make a simple-design 2-computer-cable, which will do
fine too.
: - Is NOT good to standartise that the cable will be always in port
1

:be able to connect it...
Ofcourse, but I'll add it to my homepage anyway. It shouldn't be too hard
when you're trying to detect the **name** (let's refer to it as 'JoyCom') to
try Joy-port 1 as well as Joy-port 2.
: - So, The port can be 1 or 2, and the new softs MUST detect in
which
:port is the cable, though F-16 and F1Spirit3d need the cable in port 2.
I'll add it.
: We think is not important to standartise pin usage or software.
Correct, but it will probably be useful to use a 'guideline'...
:If the hardware is the same, the compatibility is guaranteed. There are
many ways
:to establish communication between computers, and the algorythm and the
:protocol may vary a lot from case to case. So each programmer can use and
:call the pins just like he wants (D0, ACK, CLK, CTS, IN0, etc...).
Yup.
: We should make a official homepage to spread the new standard, with
:instructions and examples about how to make the communication and some
basic
:routines (but not standard routines). The MSX clubs shoud prepair some kits
:to show and sell in the next MSX fairs with some soft. The start is always
:hard, but the sky is the limit.
My homepage is (partly) dedicated to this project and contains all
up-to-date information.
: We would like to thanx Sean Young for the information
about
:F1Spirit3D, Laurens and Maarten for their ideas and work in way to make the
:new standard possible.
Thank you too.
: Yesterday (16/08/98) we made three new cables just like above and
re-programmed our game to work with the new pinout. Tomorrow the game in
BASIC and the whole source code in Z80 assembly will be in my Homepage to
download, and then you will have something more funny to test your cables.
That would be great!!! I'll link to your page as a 'JoyCom' software-source.
