Emax

Does anyone know how the internal and external scsi connectors are wired
together?  If I plug in an external zip drive, I either get no drives 
(termination
off) or only the zip drive (termination on).  The internal HD only shows up
if I unplug the zip drive.  Is there any way to use both at the same time?

Louis

Hello Louis,

What SCSI ID have you assigned the Zip drive? I'm no expert, but my first thought is that 
you have assigned the external Zip drive the same SCSI ID as the HD.
I might be barking up the wrong tree, but it's just a thought.
Happy holidays.

All the best

Dave

Yeah, ID mismatch was my first thought as well, so I tried different 
ones on the zip,
but the result is the same for all of them.

Termination is on (that's what I said in my first post).

I've tried all IDs from 1 to 6 without any luck. If it boots from
the HD, it only sees the HD.  If it boots from the ZIP, it only sees
the ZIP.  It won't see both.  It's just as if it stops scanning after
finding the first bootable scsi device.

By they way, this is a regular scsi ZIP (with all IDs available), not
the crippled blue box with only two IDs.

I finally got my Emax back in action after a long time of not being able to set it up for propper use (Emax HD/SE with Plus OS and internal SCSI )  After I got the HD working and everything seemed to work ust fine, the HD died.  To be expected I guess, and although I have and use an external Zip, the ID 5 /6 thing keeps me from booting from it.
 
The only reason i liked the HD was because the software booting from it makes using the Emax much faster than dealing with floppy access times when booting from Floppy.
 
So dead HD, and I start digging through my scsi crap, and I find an external SCSI card reader I got years ago for my MPC-60, also retired at the moment in favor of the MPC 1000 (yeah yeah, blasphemy I know, but JJ got it right, and it's small which is nice when space is an issue).  So this external drive can select any scsi ID, so I aimed to get it to be my boot drive.  Interestingly enough, with the internal HD dead (not spinning and when it was spinning giving me HD format errors whenever i tried to format it) the external card reader would not be recognized at ID 0.  I guess there still was conflict, as I couldn't get to it or format it.  So I unhooked the power and internal scsi cables from the internal HD, and got the external card reader to format (took a lot longer than I thought it should, but it has been a while) and be my boot drive.
 
I still use Zips since I have a bunch of them with sounds, and I still have a fair few floppies and like having the floppy drive around in case of whatever finding old disks, making someone else a disk, etc.  But I kept toying with the idea of mounting the card reader internally instead of the HD, just to reduce clutter and have it neat and tidy in the rack unit, but it would be a waste to just have it in there without having access to it.  So...
 
is it possible to fit an internal card reader and a new floppy drive in the emax disk drive slot simultaneously?  I don't want to lose floppy functionality, maybe with a laptop floppy drive?  Has anyone done this?  I think I may have seen this before, and I am pretty sure I am not the first to think of this or try to do it.
 
As for the card reader, I have to say it is amazing how quiet the emax is now without the internal HD.  I must say I will probably miss it's 'Wirrrrrrrclickzipzip... Wirrrrr' start up sound, but it is so nice to have it be quiet now.  So if you're thinking about it, get one!!
 
So yeah, I'm ranting a bit, I am just happy to have the emax back in action, I thought some of you might understand ;)

you should search the archives, one of the forum members, Ted, has done this
and i am currently in the process of doing this (as of now just trying to
figure out the best way to mount the drive properly since the brackets in
the Emax won't really work).

check out Ted's page here w/ pictures of the card reader + slim floppy both
installed in the Emax.  pretty cool!!!

I had a LCD full of solid blocks save one line straight across near  
the bottom.
All LED lights were on except Transpose and Preset Def.

The issue was not the Echip.

I wonder how many boards have had this failure and people threw the  
emax away thinking it was an Echip problem after replacing the LCD  
display which did not solve it....

Anyways-

If anyone has dead Emax logic. Send them to me and I can check them out.
I have a Rev2 and Rev3 board so can rule out if the Echip is dead or  
not.
Both types- the PLCC (little square on the Rev3 board) and the  
standard DIP style (rev 1 and 2 boards).
I can also quickly rule out any of the other somewhat hard to come by  
chips as they are socketed.....
SCANNER CPU, etc.....

Any of the other chips are fairly easily found and can be replaced.

Contact me and we can discuss terms.

Best Regards and Happy Holidays!
Ted

On an Emax II the MASTER 9,6 combo helps determine what it is
searching for first, and the DRIVE SELECT with the DATA slider shows
you what devices are connected and where on the chain.
