Why do you feel you need routers?
Why not just connect the PC to a switch and all the switches together?
Are these on separate sites?
Are you trying to keep the different nets from communicating with each
other and still allow the PC to communicate with each net?

It is perfectly fine to connect co-located switches together with
different units on different IP subnets. The switches will isolate the
traffic between nodes but if you are trying to isolate them then one
router would be sufficient I think.

If isolation is the goal or the sites are not co-located with the PC,
a single router at the PC with connections and static routes to
networks A, B, C would be fine. Place the PC on its own subnet
( and only allow it to talk to all three nets.

For information :

First test seams OK. So only the existing switches would suffice.

1 PC with / and another PC with / both linked to a same switch can ping themself.

I have an information on the differents LAN and this is not the same I said.
I will soon (perhaps monday) do more tests with the goods IP and I will
calculate the subnet mask for not to put 0 everywhere.

See you soon,
