EZ135 SCSI Internal Manual

[Shift838]

Anyone have a manual to the Internal SyQuest EZ135 SCSI drive?

 

i'm looking for the jumper settings. I believe I have a failed SCSI drive and want to set this one up to test. There is no jumpers which sets it to SCSI ID 0 which is SCS1 for the TI.

 

I dont' know the jumper settings to set it SCSI ID 2

When these drives are in their external case, the selector is attached to the drive via a ribbon cable with a 6 pin header. Pretty sure the three sets of pins start with pin 1 as labeled on the PCB.

 

If this isn't clear I can try to take a picture. My current test EZ135 still has the selector attached, even though I use it as an internal drive.

it's selected via the ribbon cable? I thought it was a jumper like some of the other's I've seen..

[+InsaneMultitasker]

No, the selector is attached via a 6-wire ribbon cable when installed in an external case. Otherwise, the jumpers are used. Same pins, different setup. I mention this because some people's internal drives were simply removed from the external case.

when you get a chance snap a pic for me.

I owned one and liked it till I busted the head extracting a cartridge. It was also external. The link Insane posted has an illustration that may help. Just bridge the second pair of pins, starting from the pair nearest the center of the board, on the rear of the component side.

Here is a link to a site for the manual and some drivers:

yeah, that link doesn't work and it's also the manual for the EZ135 Parallel port version. I searched like a mad man yesterday - had to google the file name to find out it was not the SCSI version of the manual.

Found this while looking for a few MDOS files today. I don't know the source - I had captured it in a text file back in 2001. I think it will give you what you need.

 

SyQuest Internal SCSI Drives

EZ135, SQ3270 and SQ3105 Internal Drives

All SyQuest EZ135, SQ3270 and SQ3105 internal SCSI drives ship with two

pin resistor packs installed on the bottom of drive immediately behind

the 50 pin SCSI connector. To remove termination, simply remove these

two resistor packs. To restore termination, reinsert the resistor

packs into their receptacles.

=============================================================================»

a. Locate the SCSI ID jumper block on the bottom right of your SyQuest

drive. The SCSI ID jumper block is a row of 8 pin pairs. Refer to

the figure in your installation guide.

NOTE: Store unused jumpers on one pin of positions 1, 2, and/or 3

by inserting the jumper onto one pin only.

NOTE: If you will be attaching other SCSI devices to your SCSI

flat ribbon cable, you must terminate the last device on the SCSI chain.

It is the physical location of the drive, not its SCSI ID, that

determines the need for termination. Terminate only the last physical

device in the SCSI daisy chain. You must remove termination from all

SCSI devices that are not the last physical device in the SCSI daisy

chain.

Cabling SCSI Devices

SyQuest fully endorses the Apple Macintosh SCSI cabling standard. All

SCSI cables should be 26 AWG (gauge), twisted pair and fully shielded.

TERMINATION:

SCSI Terminator should be ACTIVE when used with a EZ135 and WHT SCSI card.

Passive termination may result in errors.

Errors will usually occur during copies.

very helpful.

Let me bump this, I'm look for the Syquest EZ135 SCSI Manual, does anyone have that?

 

Failing that, when my drive comes on, it makes a clicking tone, the insert/eject lever then 'kicks open' on it's own.

 

I'm guessing it doesn't like that platter anymore?

[+FarmerPotato]

I used a lot of EZ135s (SCSI, external) in the 90s. I recall that clicking sound meant the end. Unless it is a problem with the drive.

I found the EZ135 drives to be more reliable than the Syjet 1.5G, too (trashed one of those drives).

[+InsaneMultitasker]

The clicking/lever issue you describe happens to me if the platter is slightly out of alignment.  Try ejecting then insert/remove 2-3 times before locking the lever.  It the platter is rejected and other platters are OK, it's better to put it aside or trash it.  Like FarmerPotato points out, the drive could be at fault, too.

 

I've been using EZ135's in my main system (and Heatwave) for ~20 years.  The platters can get ornery after 1-2 years of constant operation.  For my primary drive, it looks like I retired the platter every few years based on the ones still sitting in my storage bin.

[+dhe]

My time being essentially free to me, I put another platter in.

I used du2k to format, reboot.

I then used dm2k to copy from scs2, to scs1.

Finished without errors.

Did a dir of SCS2, no errors.

Tried to read a subdirectory on scs2, lockup.

Rebooted

Tried several subdirectories on scs2, all read without errors.

So essentially back to where I started! ?

 

O'yea, EPSON printer ribbons get mighty dry after 10+ years, now I'm back to where I started with that also.
