I have had good luck booting Ultra 1 boxes with that exact CD-ROM drive.
 Last summer I had a group of three Ultra 1 boxed I'd gotten at auction
that had no CD Drives, and a pile of PowerMac 7200s with that drive in
them. It was a no-brainer to scrap the Macs and put a CD in the Sun
boxes. I've booted Solaris and NetBSD with those drives, using 'boot
cdrom' from the OB prompt.

I have heaps of those Apple drives, if anybody ones one or a few for the
cost of shipping just write.

As to why the Ultra 1 was 'thrown out': there seem to be a scad of U1
boxes being surplused these days. Mine I got at auction for $12.50
each, and possibly would have gotten them cheaper, but didn't want to
play 'chicken' with the auctioneers, who sometimes have a tendency if
they think you're 'camping' to end the 'select item from the pile'
bidding and sell the whole lot, sadly too often to a PC-only drone who
ends up pitching or scrapping anything that won't run Windoze.
