Hmm, I remember 4D /25 and /35 machines being picky
about CDROM drives - the
/220 may be the same and you'll find you need to experiment a bit to get
something that works (512 byte block support is a must, of course - but even
amongst those drives, I ended up with one drive that'd work with Indigos and
not 4D machines, and another drive that'd work with 4D machines and not
Indigos :-)
Yeah, SGI machines are fussy about CD-ROM drives. I've got one that I
used successfully with Octanes, but they are a later breed of SGI box.
Do your machines come with a keyboard? [...]
There wasn't any listed in the lot, just the base unit. The SGI
keyboards are probably lumped in with another 100+ PS/2 PC keyboards
because we all know that keyboards on computers are interchangeable,
right? ;-)
I have some keyboards for my PI 4D/20 and 4D/35 though, so I should be
OK. Plus there's a guy that sells a keyboard adapter circuit on ebay
for $40.
I wonder what the /220 is like for speed? The /25 and
/35 machines were
slooooow, even for old versions of IRIX (although given the nature of this
list, that's not a big deal :-)
sgistuff says the 4D/220 has dual 25 MHz R3000s with 40 MIPS and 8 MFLOPS.

4D/20 has single 12.5 MHz R2000 (10 MIPS, 0.9 MFLOPS),
4D/35 has single 36 MHz R3000 (33 MIPS, 6.0 MFLOPS)

I have two of these Personal IRIS machines (4D/20 and 4D/35, I think),
along with a rebadged Control Data PI.
