I can't answer specifics about the 4400, but I can answer general
question on Harris Equipment. (We are the happy owners of an HCX-9)

Harris supports SCSI and SMD on the VME bus so I would expect SCSI to
be available.
> Eithernet interface?
I know all machines support TCP/IP and Ethernet. Bets are on a 15pin AUI

Harris has an excellant compiler - hf77 (suprise :-) it supports most VAX
extensions and all the wonderful Harris H-series extensions

Don't know about any of the above.

Yes no problem here. We use it on the HCX.

I'm not sure. But it could be added easily.
>4. What will it cost in maintenance: hardware and software? Currently
Again depending on your configuration.

You didn't mention the OS you were getting (there are three UNIX versions
commercial, realtime or C2 secure) so I don't know the application.
Harris is very strong right now in real-time systems for data collection and
simulation. The Nighthawk's context switch speed is among the best in the
industry. If you have a real-time application Harris is your best choice.
Otherwise, its a more difficult decision to make.
