Anyone got any idea what the following hardware would be worth (in
Australia)?  These models would have been first released about 1990, and
the particular machines have been in use continuously since about 1991.

I am not selling these, I just want to know estimates of their value as
I may buy some of this gear depending upon the price.  Values in other
countries would be useful - if so let me know the currency you are
quoting in.

All machines are Hewlett-Packard 9000 series

1. HP Model 710
   40? Mhz PA-RISC processor
   64 Mb RAM
   400 Mb internal slow narrow SCSI drive
   Additional empty slot for another SCSI disk
   10 Mbps ethernet (coax) - standard
   2 serial ports (max 38000? baud) and one parallel port - standard
   19" colour monitor (HP A1097D Southern Hemisphere monitor)
   HP-HIL keyboard and mouse
   HP-UX 9.03
   
2. HP Model 715/50
   50 Mhz PA-RISC processor
   112 Mb RAM
   2 x 525 Mb internal slow narrow SCSI drives
   10 Mbps ethernet (AUI) - standard
   2 serial ports (max 38000 baud) and one parallel port - standard
   19" colour monitor (HP A1097D Southern Hemisphere monitor)
   HP-HIL keyboard and mouse
   HP-UX 9.03
   
3. HP expansion tower
   7 slots for slow narrow SCSI devices
   3 x 1 Gb disks
   DDS-1 compressed DAT drive (faulty - ejects all tapes)
   CD-ROM drive (single speed?)
   SCSI cable and terminator
   
4. HP expansion tower
   7 slots for slow narrow SCSI devices
   2 x 1.5 Gb disks
   DDS-1 uncompressed DAT drive (faulty - ejects all tapes)
   SCSI cable and terminator

5. HP stand-alone external DDS-1 uncompressed drive (working)
   SCSI cable and terminator

Last question is how much does RAM cost for these machines?  I don't
think they take any type of standard PC memory.

All the disks are HP supplied, either HP branded or SEAGATE or QUANTUM.
All equipment is used and is about 7 years old and has seen continuous
use.  As you can imagine some of the disks are quite noisy.  Some of the
RAM is not HP supplied but is from Kingston.
