Emax

Jammie-

Wasn't speaking in regards to this, and you.... I have had several emails over the past days that indicate this may be a problem - that how SCSI works in samplers and in relation to the drives isn't being explained by other places selling these drives.


Thanks,
Ted

thanks ted yes i have your original message

i dont think there are any samplers that allow luns 

luns where set up for multi cdrom machine drives so that you could access different cdroms 

basically a server type multidisk

great for pc and mac but pita for scsi samplers especially scsi 1 like the emax

our problem was the actual software for the emax was the problem they were not working

as i put your drive that i had from you and it would not work either even though i it did before it was the os that i was using from the files section

so i new it was not your drive and not my new drive

thats when i decided to get my archive drive out and find my
e2 files and os files that i had backed up

once i found the os i loaded it onto a new floppy which i formated in the emax then i loaded that into the emax with your drive and it worked then i swapped drives and it worked on my new drive 

so all was good i have updated the os,s in the files section to include the proper se 1.1

the sehd 1.1

the hd plus 1.0

thanks for your help

can you give me a price for the 2 chips thanks jammie

Subject: [emax] PCD-50b drive in Emax

I think perhaps it needs to be stated for folks buying these drives from other sites about its known limits when using the PCD-50b drive in the Emax.
I believe I was quite clear in my statements when selling the batch of drives I had, but perhaps the other sites are not explaining the compatibility.

Emax is SCSI-1 TARGET only (SCSI ID) based SCSI, which has no support for LUNs.
PCD-50b drives are TARGET (SCSI ID) and LUN (Logical Unit Number) based SCSI (which was added in SCSI-2 or SCSI-3 specification).

Therefore, Emax can ONLY access TARGET (ID - which is set with the ID jumpers) LUN 0, because it cannot detect or send to specific LUN #s.

Where a LUN # isn't specified, a SCSI command will be interpreted by the drive as going to LUN 0.
It so happens that the PC Card slot is LUN 0, and therefore that slot works with Emax.
No other slot will work in the Emax.
The other slots are LUN 1, LUN 2, etc.
There is no known way (unless there is a firmware hacker somewhere on the forum) to make a different slot LUN 0.

I hope that clears up the misconceptions out there floating about.

Regards,
Ted
