I got two responses, thanks to
        Kurt J Lanza <i won't post their email adress>
        Mike DeLooze <without their permission>

They gave me the hint to look at RFC 1340:

1340 Assigned Numbers. Reynolds, J.K.; Postel, J.B. 1992 July; 138
p.
      (Format: TXT=232974 bytes) (Obsoletes RFC 1060)

>From RFC 1340, page 12:

   gopher 70/tcp Gopher [MXC1]
   gopher 70/udp Gopher [MXC1]
...
   www 80/tcp World Wide Web HTTP [TXL]
   www 80/udp World Wide Web HTTP [TXL]

A quick look through some archie sources gave me the name 'prospero'
and the assigned ports, which i could verify in RFC1340, page 17+23:

   prospero 191/tcp Prospero [BCN]
   prospero 191/udp Prospero [BCN]
...
   prospero-np 1525/tcp prospero non-privileged
   prospero-np 1525/udp prospero non-privileged
