I have two Zyxel ISDN routers here that need to go to a good home. We have no use for them anymore but somebody may be able to use them. Here are the details:
Zyxel Dual BR ISDN Access Router - Prestige 480 (£20)
Zyxel ISDN Internet Access Router - Prestige 202 (£10)
Maybe somebody could you them on a networking course or something similar.
