We have a Digital DAT drive attached to Ultrix (later to become OSF) on 
which we use 90 m cassettes with a capacity of 2 GB (uncompressed) and
4 GB (compressed).

We will also acquire a Sun DAT drive to be attached to a Sun machine.

Moreover we will collaborate with others who will have an HP DAT drive 
attached to HP which they say to be able to write with a capacity of 8 GB 
on a 120 m cassette.

Can somebody enlighten me on the compatibility ?

1) I assume uncompressed (2 GB on 90 m) cassettes written on any of the
   three (DEC Sun HP) can be read on any

2) Can 90 m tapes with compression to 4 GB (readable and writable from
   DEC) be compatible with 4 GB tapes (read and write) from Sun ?

3) the same but from HP ?

4) I assume instead the 8 GB HP-written DAT will be unreadable on either
   of the other two systems
