This program, "4 on a row", should be able to play over a Interface1 or DISCiPLE network,
if one off those interfaces is connected to a ZX-Spectrum.
ofcourse you need 2 off those to have a network.

If you use an emulator it should work with RealSpec-DOS, under w3.11, win95 or win98.
XP has an win95-emulator but i have no idear atall if it will work.

IN RS-dos you first have to set up the TCP/IP connection for LAN use
that is key ALT-F8
there you fill in the IP adres off the OTHER PLAYER.

one player loads "4 on a row" and starts

the other player should receive a net-question to install on that speccie
then every thing should go by turn.

I hope it will work
it did work when i used w98 but now i have only one-pc and use w2k,
so if it is not working or bad PLEASE
