Questions about Personal IRIS

[James P. Loan]

I have a few questions about the Personal IRIS, and I'd appreciate
any help. I'd ask our sales rep, but it takes us a week to reach
each other. We currently have a 2400T and we are about to order
a 4D/25 (prod# W-4D20G-38). We have also ordered the software
development package (S5-DV01) and the X-window package (S4-X113D).
The two machines will be connected by a 10Mbit Ethernet line.
My questions:

(1) I assume that the Personal IRIS comes standard with a 19"
    monitor (it doesn't say so on our quote), so we'll have
    the old 19" (1024x768) monitor from the 2400T as well as
    the new one (1280x1024). What we'd like to do is be able
    to run graphics programs on one (or the other) cpu and display
    them on either of the monitors. The scenario is that
    someone sits down at one of the monitors and is able to
    runs graphics programs located on either machine.
    Is this possible? If so, does something need to be done
    to the system before it is shipped to us?

(2) We are getting the so-called Super Graphics Upgrade to
    give a total of 56 bitplanes. Are the 24 z-buffer planes
    ONLY for z-buffering, or can we use 48 for color w/o
    z-buffering so that we can use RGB mode in double-buffer
    mode?

(3) Does the SGI WorkSpace software and Diagnostics software
    come standard?

(4) Is the data cache write-through and/or virtual-addressable?


Thanks in advance,
