Share your knowledge on these two classic MPCs

Let me preface this post by telling everyone that I have done the SCSI Card Reader modification in my 2000XL and I have built many a computer plus I have searched, and I frequently visit www.mpc3000.com for reference, so keep the flames in your thrower.


Now, I have purchased all the parts necessary to make the hook up and it seems like a very simple job. I've opened the MPC 3000 and Im ready to get goin, seems like at most a 15 minute job. But here's the thing.

The Power Connector.


The power connector on the back of the ZIP I receieved resembles a normal small four pin floppy connector. I have extra power connector parts and the floppy connector I have fits perfectly.

This is diiferent from the internal SCSI card reader mod I performed in that that reader accepts the large four pin power conenctors that all IDE devices take as well. So I had to peform the famous power connector modification.

My first question is will this drive work correctly with the 3000? If yes, would a power connector mod even be necessary as the power supply in the 3000's floppy looks like it would fit into the zip without a problem. I am just not sure that that power connector is supplying the right voltage to power the zip without any modification......

Zip Model is Z100Si
S/N: SJ3U36D42F

Your insights are greatly appreciated!

I performed the same card install in my 2000XL with the power cable modification. On the 3000, voltage shouldn't be a problem and yes, the ZIP drive "should" work in the 3000, so long as the power connector actually fits the ZIP drive. I've been sysadmin/network engineer for the last 13 years and I can say that the power requirements for a floppy drive and an IDE/SCSI device are basically the same.

Thanks for the reply.

Whats bugging me out is the fact that on www.mpc3000.com there is a clear power cable mod for the internal zip install. I am wondering if some zips take the normal large 4 pin IDE type power and others take the floppy power?

Not sure.

yo, why not try to fit a card reader in the 3k? all that effort isnt worth it for a zip... nevermind, i just read your other post..
