Is it worth it the effort?

Why don't just buy a new 900? :?

Definitely worth the effort. Takes all of 3 minutes to get a bunch of extra features. As far as I'm concerned, I've extended the life of my R700

WORTH THE EFFORT? Are you kidding? It is sooooo much easier to push a few buttons on an MZ-R700 than to spend all the extra money to buy an MZ-R900. If you have enough money to easily drop the extra bucks for an R900, then could you do me a favor and buy me an MZ-N10? Hey, Christmas is coming...

By the way, don't try this trick on an MZ-N707. It works, but it makes the buttons go screwy. You get in extra trouble with an MZ-N707 due to the keypad layout. When the buttons change, the stop button becomes the volume down button but the pause remains the same. That creates a problem because the stop and pause buttons are on opposite sides of the little button rocker thingie. I had to take my recorder apart, find the right spot to solder to enter service mode (somewhat of a challange with a service manual...speaking of which, anyone have a service manual for a MZ-N707?), and use the remote to navigate the system to change the vaules back (mine were A0 and 50.) Unless you'd like to change your control layout on your recorder in exchange for adding a few features, don't bother trying this trick out.

Are you forgetting something? An R700 is soo huge!!

I prefer my R37 to an R700. At least it's about as slim as an R900..

I'd easily fork out for an R900 (wow, they're so expensive :roll: ) than have a bulky R700. If I had an R700 already, then yeah, I'd do it. Providing I didn't press pause in the wrong place :D

How did they find out about this?

Maybe it's also possible this way to find out how the PC->MD transfers on NetMD recorders work and to add MD->PC functionality?

Hey guys!

I posted this because i want to get some things clear

-this mod rulez if somebody misses he PLAYLISt function in the 900

-I did it with help of the Service maual, my thoughts, luck, and a month of ork, when i rendered my recoreder unoperable about times, resetet it and started all over again.

-It was not EVER meant for the NetMD, beacuse i do not own one.

Im still waiting for one though, so ill start my work on it when i get it. and it will work with all the buttons normal and so on. i just need time.

And also i dont think it has the MD->PC transfer there, beacuse somebody from OpenNMD would find it sooner (or am I just that smart ;))

Anyway, ill tell you guys everything when im done.

If you ever try the hack on the 707 as someone told the keys will be screwed up.. (I tried it myself)

But you don't have to open the unit to get back into the service mode... just replace the vol - key by group/cancel and follow the same procedure... that will work....

Hey MoV1, how did you reset your recorder? I've been playing around with the service mode on my MZ-N707 and fixing large errors is getting to be a pain. How can you reset the whole system, using an NV Reset? i thought that only did power stuff...

Hey, Peter (MoV1)

I own an MZ-N707. When you get your NetMD and maybe try to figure out why the MZ-R700 trick messes up the buttons on the NetMD, if you need any help testing, researching, trying different combinations of settings, or whatever, give us a hint of what to do. I'd like to be a part of the project to get this thing working on the NetMD, that'd be great. Thanks.

Hey, guys,

I've been playing around with my MZ-N707 trying to get this R900 hack to work. It seems I have finally found the problem. In order to get this thing to work, do only the second step of the hack and skip the first one. In other words, do the following:

1). Enter the serice mode.

2). Press VOL + -- you should see "MANUAL" displayed on the left and "0 00" on the right.

3). Press PLAY -- you should see "Laser" on the left and "0 10" on the right.

4). Press VOL + 5 times -- you should see "F Code" on the left and "0 60" on the right.

5). Press PLAY 2 times -- you should see incrementing numbers in the first 3 digits of the left display and "0 62" should appear in the right display. The last two digits of the left display are the value you want to change (it is "50" on my MZ-N707, but write this number down!).

6). Press VOL + repeatedly until this reads "7B" (you can press VOL – if you go past it).

7). Press PAUSE

8). Exit the service mode.

That's it! All buttons function normally.

UPDATE: After testing the M-Timer and Personal Disk Memory options, I determined that only the M-Timer option actually functions correctly. So far I haven't been able to use the Person Disk Memory, although it is listed in the menu and appears to be operational. It is really not.

Anyone tried it on a MZ-R500 yet? Tell me how it works out, please.

This hack is perfect for the MZ-R500! I always wondered if there was something like this out there. Anyone who thinks it would be better to just go out and buy a 900 machine is nuts. It took me all of 5 mins to do the mods, and I've never even messed with service mode before. I've noticed no adverse reactions to the hack. It does add a headphone/line out switch which wasn't mentioned in the instructions. Ah, the beauty of mass production... (Now only if I could get my fiance to give it back to me :wink: )

i did the hack and i don't like the way the sound settings 'sound.' i think they sound way shittier. i'm using the headphones that came with the r700 and a pair of the new sport style ones...but if the players sounded better with out the hack, you think i should change it back?

or am i missing something? do you absolutely need the lcd remote to access the other functions?

well in that case you should try listening to ur r700 on like better headfones 2 c if this is the case (say the mdr-e838's will b suffice or if u can manage 2 get a pair of e888's then that would b even better :P but otherwise u should try ur sport style earfones)... if on these headfones they do indeed sound worse then you should undo wot u did in the service mode....i'v tried the hack myself on a r700 and i think it sounds the same....

and no you do not abosolutely need the lcd remote 2 access the other functions, u could buy 1 if u wanted to but i c no point in doing so other than it being able 2 access some other functions that the r700 remote can't...

Streetstyles phones aren't much better - look for some Sennheiser MX400/500s. Super cheap earbuds, ~$17US, and super sound. Excellent treble, and bass response that is amazing from an earbud.

Hey, guys,

I've been playing around with my MZ-N707 trying to get this R900 hack to work.  It seems I have finally found the problem.  In order to get this thing to work, do only the second step of the hack and skip the first one.  In other words, do the following:

1).  Enter the serice mode.

2).  Press VOL + -- you should see "MANUAL" displayed on the left and "0 00" on the right.  

3).  Press PLAY -- you should see "Laser" on the left and "0 10" on the right.

Are the NetMD functions still working if you twaek MZ-N707 to MZ-R900 :?

Yes, it should - all it does is change the sound settings, and playback settings, nothing that will affect NetMD operation.

Ok guys. I found something new.

First of all, i figured how come I have Mic Sensor and you guys do not.

My first value is not F7 but FE. The article should be updated shortly.

For the N series reset- Every model has a different reset procedure, and I do not own one as for now. But don't worry about it. Eric is trying to fix me one, so I can start hacking the N series too. I don't know how Erics timing is going, but from the time I get the unit, it should take max. 1 Month.

As for the PERSONAL function- IT WORKS BUT,

as you all know, the 900 has a FLAT battery. That means that

a) the user doesn't change the battery frequently

b)if his batteries run out, he usually charges it or plugs in the AA part.

The significance of this is that the unit has enough power to keep the memory alive. (or I'm wrong).

Just try it out. Do some wild stuff on the MD (like a playlist), run PERSONAL, take out the MD and put it back. You will see the PERSONAL show up again and setting up the values you saved. The rpoblem is that the AA battery works differently (after about 10 mins it TOTALLY quits using the battery) so it clears the Memory.

And about the Mic sensor, according to Eric the 900 has extra circuitry on the Mic in, so we believe that the Sensor won't work. Try it out people and tell me if it works.

I guess that's all.

And for the N series hack, try it out yourself, but once I get the unit ill write a paper on everything.

and if somebody screwed up their R series unit, im in progress of writing a paper that shows how to reset and adjust everything back (hey, once you reset the EEPROM you lose everything, inluding the laser settings!! But don't worry, the unti has an auto adjust feature :)

See ya!
