Akai S1000 / S1100 samplers

when 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.

ewan.

yes, they are all slightly different,  but they all share the exact
same SCSI card, so the configuration rules are the same. terminate
both ends, and nothing else.

I would expect to find the internal scsi connector terminated on
Samplers without an internal HD fitted. but not the external one.

I was pretty surprised that I had to remove the resistors from inside
the Sampler. but when you remember the SCSI rules, it makes prefect
sense.

I also have an apple cd-rom drive and it works perfectly. and a zip drive.

I found all my SCSI devices and cables at a fleamarket, it took some
hunting, but eventually i found them all. much cheaper than ebay!

terminators are either resistor packs that fit onto a circuit board,
or and external "useless plug" with no cable, but maybe a passthrough
connector.
on more modern SCSI devices you might find a switch to enable
termination or even automatic termination.

its quite likely that you cdrom has internal termination

you are right,  SCSI ID 5 is the default place to load an OS from.
the s1k samplers can only speak to one SCSI drive at a time. the hdisk
subpage of the disk page lets you change the SCSI ID that the sampler
is trying to talk to. but this is reset to ID5 on startup
you can also eject a CD/Zip by choosing PARK. in the hdisk page.
although it is designed for turning of harddisks nicely.

if it works then don't change anything though!


one thing to remember is that after changing cdroms you need to try
accessing the cdrom drive a few times before it gets read sucrssfully.
its perfectly normal on my setup anyway.

ewan.

Apple CD600i should work, yes.

Again,- internal S-1000 / S-1100 SCSI ID is #6,- period.

You access SCSI ID #5 from AKAI menue WHEN your ext. drive is set to ID 
#5 ...
understand ?

There�s normally NO harddrive installed in an AKAI S-1000 or S-1100 !!!
Only when the model name is S-1000HD (or S-1100HD, if that existed).
There are no mounting brackets or HDD cage available inside a S-1000 or 
S-1100.
