Akai S1000 / S1100 samplers

Hi,

I have S1000 with SCSI board, OS3.0. I can not read any of my CD-ROMs (I used the same Toshiba drive with Kurzweil K2000, Apple Mac SE and my older Akais S3200XL several years ago).

When the CD-ROM drive is on and S1000 is then switched on, the LED on the CD-ROM light up and the drive starts to make a noise (disk is rotating). Then "Waiting for hard disk ready" appears on the S1000 and CD-ROM drive stops to do anything. 

There are three jumpers on the SCSI board. One is switched off.

I used to have S3200XL with the blown fuse problem (replaced and worked for years then). Is there the same system in S1000? Where is the fuse?
