Emax

So if you switch SCSI ID's on the Emax I and put in a different Card it won't recognize it?  I've switched Zip disks that way before and It was fine, maybe even without changing the ID.  I only have one CF card in an external scsi box. so I can't check.

 

Jammie, does the emax internal cf card have the problem you mentioned with Ensoniqs?

its all down to the scsi interigator of the samplers some samplers only interigate at start up so if you switch of the cf card reader then it would not see it when switched back on unless you reboot the samplers some samplers like the later akai,s sxxxx range do interigate when you move from scsi id they have the option of mounting drive so it rescans the bus 
the kurzweil kxxxx has the same option as do the yamaha axxxx range

the problem with the cf-ide adaptors is that the cf is seen as the hard drive when removed it loses the drive

the scsi to pcmcia card drives are different as the scsi bus see,s the pcmcia interface and see,s this as the hard drive thats why it can see 2 drives with there own scsi id

removable media was not out when these samplers were built thats why they had fixed drives and why they only had 20mb capacity back then 20mb was massive in terms of storage same as samplers that had 32mb memory was seen as never needing to be surpassed but now we have samplers with 256mb memory and hard disk streaming

but back in 87 cdroms was the thing and hard drives was only for the rich as a hard drive was almost as expensive as the sampler its self

the scsi to ide adapters are for making a hard drive system into an bootable imbedded system they used solidstate drives for this for military and dangerous locations were a ram drive was better with no moving parts to go wrong

they were also designed for using cheaper ide equivelants hard drives and cdroms because they were more mass produced for the pc market

they were never intended for use with samplers it was just us engineers and hobbyists that tried the cf-ide and scsi to ide cards with different samplers some cards work with some some cards work with others

i use both the acard and the iodata scsi -ide adapter cards as some work for 1 sampler type were as some work for others and it also depends on the cf-ide adapter and what cf cards are being used

i use type 1 san disk 32mb cards for the emax 
and i use 512mb type 1 for the emax 2 i found that the ultra type 2 cards are to fast for the scsi implimentation of the older samplers but they are good for the later models of samplers

some only work externally especialy on the ensoniqs as the floppy drive power is boot driven from the rom and because of this there is a delay when switching on the machine and the floppy power bringing the scsi cf drive into play missing the interigator scsi buss scanner and so it says no drive

I can't directly comment on the emax2, but if it uses the same 5380 SCSI
controller, the SCSI bus controller does not implement hot swap capability,
I believe that is done in software or in the SCSI BIOS.
Floppy drives have a signal on the bus called the "change line" that
indicates that you removed the disk and inserted a new one.
SCSI implementation on this IC doesn't have any sort of "changeline"....
Even so, the Emax 1 firmware doesn't implement removable media.....

From my experience with my Emax 1, I could swap the cards successfully
sometimes for formatting purposes (not always).
But if I had a card with banks, and swapped it, my Emax 1 still thought the
old catalog banks were there from its initial read, not new ones.

My MicroTech DPAI-SCSI has 2 slots, so I have 71 banks at 1 time (including
the floppy)- for me that is enough.....

I am using 32MB Sandisk Transflash on the Emax 1 with a generic 5 in 1
adapter. I have also used the Dazzle SD adapter as well.

Ted
