Yes, they do not even offer OS update for old Neoware terminals - HP support
sent me an e-mail with information that my model is not supported and they
recommend to buy new clients, of course HP-made ;-)
It's got a 300 MHz CPU and 32 MB RAM (probably SD-RAM, SO-DIMM), right?

I think so - I did not check details, but im sure of 32 MB RAM and 16 MB
flash disk with operating system. This is quite old stuff from the 20th
century...

Hmm, after first negotiations with management I think it will be easier to
buy new thin clients than upgrading old ones. I found some proposals on
levigo's website but no information about pricing and availability outside
Germany.
Above recommended hardware for thin clients should be published on OTC
website, the requirements for server could also be updated - no info on
server power per thin user is there (I have about 30 thin users - how many
cpu power/ram/hdd I need for comfortable work?)
