MPC 2000 SCSI Issue - Blown fuse?

Hey Gang- thanks so much for checking this. We are a non-profit music school that offers free hip-hop classes and the kids are dying to get back on the 2000!!!

We've been using this old 2g for a while. It came to us with a bad floppy drive and a zip with the OS disk which has been working fine. I forgot the SCSI power supply one afternoon and in a panic at the school I tried to power the zip with my laptop adapter (same size end). It lit up, then turned off, never to work again even with its original Iomega power supply.

Since then we have replaced everything but the SCSI cable itself, running a new functioning Iomega Zip. Here what happens when we try to load it:

-MPC starts and recognizes the Iomega Zip on SCSI port 5
-This lasts on about a second, then it move on looking for different ports
-When it hits SCSI port 5, during that small amount of time, the zip drive lights light up as you would hope, but it just doesn't get at the OS disk for some reason
-After it passes port 7 it asks us to insert the OS disk

Thanks so much for your help and advice! These kids really love the MPC - who wouldn't???

Hmm, it takes 5V 1A power supply to power up the scsi zip drive. if your laptop power adapter has a different power requirement beyond the 5V 1A, then the zip drive may be ruined. the problem is if it has spread to the sampler.

try geting your hands on another scsi ziip drive (termination switch and scsi id switch) and try it with the mpc2000 to see what results you get.

just remember, the zip drive requires a 5v 1 a power supply.

LADiego:

Thanks for the reply. I have a new zip including a new os disc and its still not functioning well. The problems I listed (stalling on SCSI 5 for a sec, then moving on) are all based on using the new, proper zip.

damn zip drives... O.o... would be cool to look for an alternate storage medium

Yeah, I home-installed the internal CF card reader from JD on my personal 2000 and its been working awesome.

Unfortunately this is not in our budget at the non-profit, so I think zip is the way to go. Unless someone knows a more cost effective alternative. I actually love the old zips when they're working well...

when they work it's great, but that is where the problems begin... cause they aren't reliable.

you know what? cause you and I both know the cf card readers (scsi) are expensive... maybe take a look into a scsi hard drive or something. obviously the ones marketted as "for the mpc 2000" will be pricey... but maybe you can find one that you know is compatible.

make sure the termination switch is set to on.

Yep- We have a zip with the termination on-off switch and the scsi 5/6 switch.... and I've tried every possible combo honestly!

Realizing that it should work with the term set to on and the scsi to 5.

A bad SCSI cable can cause this kinda problem.
If you didn't get one with the new drive, the 25 pin to 25 pin SCSI cable you need usually sells quite cheap on ebay. It's the next logical step to take in trouble shooting before you go to the hassle of getting the fuse checked/replaced.

If you do need a new fuse, then someone with some soldering skills should be able to replace it. I don't have the specs but, self resetting fuses are available now and some are suitable as SCSI fuses. With one of these you should never need to solder in a new fuse again.
