Congrats Camiel!
We had an C34 and an C220 in the Computing Centre of out university here
in Freiberg (Saxony). I don't had much todo with it, but I've used The Metrum
Robot with two RSP2150 later for Backups at a small ISP.
I have still some quarter Inch Tapes labeled with golden Convex Labes
here laying around..but the contents are'nt original anymore.
Regards,
Holm
