Emax

Garth-

I have the binaries (from Emu) for SCSI and recreated the chipset to install SCSI on the REV2 / REV3 board.
It is available.

It is 20MB drive size and holds 35 full disk banks per target (SCSI ID #) with a total of 6 possible connected drives.
With PLUS OS, the transpose key switches between SCSI target #.

All 35 banks from each target are available from the Emax menu for load / save.
It�s not hot swap (Emax limitation, not the drive limitation), but I have a 2 slot (target not LUN based) MicroTech drive, so I have 70 banks (+1 floppy).
I can copy from 1 target (PC card slot) to another to make a backup of the full 35 banks without power off, etc.

I also still have slim floppy in there, because diagnostics, etc run off floppy...

Regards,
Ted

OK, thanks. That's what I thought. The earlier Ensoniq's were like that too.

OK, thanks. I'll have to start including in our programs a bulk thing that standardizes the OS over many images. Shouldn't be difficult. We are in the last stages of writing and creating Emax I floppy images, mostly for the purpose of floppy emulator use. Chicken Systems programs read any Emax disk or image but doesn't currently write to them.

Lastly, we have a Emax SE here. They didn't come with SCSI (the SE Plus did). I see posts here going back to 2010 about a 3rd-party SCSI. Is it available, do most Emax I people use them, and how useful is it because as I understand the Emax is only 0.5mb as most? (SCSI is fast and fun but if you only have half-a-meg it devalues SCSI quite a bit.)
