I owned S1000PB and still own 1 S1000 as well as 2 S1100,- and because the OP mentioned compatibility w/ other samplers, I\ufffdll comment on p.ex. EMU too because I own a EMU E64 in addition.
1.)
All my non-HD AKAI Sampler models work w/ a CD-ROM drive, a HDD, a Syquest removable media drive and a MOD in a SCSI chain !
I did nothing to any of my AKAI sampler\ufffds SCSI-card internal termination (if it exists at all since there isn\ufffdt any HDD inside).
Successfull usage of a SCSI CD-ROM - drive depends on brand and type of the drive !
These should be normally 2x / 4x speed,-\ufffd 8x speed sometimes works too.
Old Apple 4x drives work for sure, I\ufffdm using a very old one w/ a caddy and another one without caddy.
Old TEAC work too.
If it is the last drive in a chain, it should be terminated, mine work w/ passive and active termination alternately.
2.)
SCSI-drives tested/ working w/ other sampler brand/model, p.ex. EMU (or Yamaha, Kurzweil etc.),- often don\ufffdt work w/ old AKAI S-series samplers.
3.)
Compatibility also might depend on firmware version of the optical drive, not only brand/speed.

\ufffdwhen I first tried to connect a cd-rom drive to my S1000hd I
discovered that the SCSI card was terminated on the inside. I had to
remove the terminating resistor packs before it would work with
external.SCSI devices. and use an external terminator after the cdrom
drive.
both ends of a SCSI chain must be terminated, always.
