I^2s are cool.  Are yours teal (likely to be R4k) or purple (likely to be

They take 72-pin real-parity SIMMs, up to 16 MB (most teal ones) or 128 MB
(late purple ones) per SIMM.  You can, it seems, cram a gig of RAM into a
late R10K purple I^2.

They will run fine off the external SCSI chain until you find sleds.

The same CD-ROM drive that boots your Suns will boot the I^2s.

I think you can talk to them through the serial port, using a Macintosh
modem cable, and maybe a null modem.  That should be good enough to get into
the monitor and use the "hinv -t" command to get the specs on what you have.
