[sdiy] Ensoniq EPS SCSI question

[rkmoore at memphis.edu]

Hi everyone,

Sorry for the "how do I fix it" question, but since ensoniq's death, 
repair of their keyboards has become a DIY task.

If anyone has experience with the SCSI interface of an EPS, please read 
on:

I have an original EPS with a 4x expander, the ensoniq scsi interface, 
O.S. 2.49, and ROM version 2.40.  I'm trying to connect a MASS 
microsystems syquest 44MB SCSI cartridge drive to it and am using an 
external terminator plug.  I have been using info from the Chicken 
Systems website as my only resource.  

The sampler doesn't seem to recognize the device.  When I try to access 
or format the SCSI drive it tells me "invalid scsi device" or "SCSI 
device not connected".  I'm not using SCSI ID#3, and I have a couple of 
different cables just in case one is bad.  One curious thing is that 
when the sampler boots up it displays "SCSI INSTALLED", but it doesn't 
follow it up with "SEARCHING FOR SCSI DEV" as it is supposed to do.  
Also, the drive's access light never blinks in response to 
a "negotiation phase" between the sampler and the drive.

Any insight would be greatly appreciated.  I have very little 
experience with SCSI drives.

Thanks,
Richard Moore
