About that very high price: I think that may be a joke. DtCyber
certainly always used free and open source. And it still lives in the
FreeBSD ports tree. It's at least possible that this was done as a
move of protest against BT Consulting's move to stop granting free (or
even reasonably priced) hobbyist licenses for antique CDC software...
It really is a shame that the only company that treated the hobbyist
use of its old platforms as a good thing, was DEC. It's just a miracle
that HP is still allowing things like the VMS hobby license and the
36-bit hobby license to continue. If that ended, we'd be stuck the IBM
PD-era stuff as the only legally emulatable big iron :(
