Hi folks. I'm new to the forum.

I'm totally disappointed, initialy my KN6000+EW65NX was in version 7.0

After found the 2 floppys downloded from Web of the 7.1 OS, I start the upgrade !! But failed during the second disk read. -> Only one solution, power off my KN.

And now, after a power on, blue screen and no sound !!

So what can you suggest me as help and repair the situation ?

Maybe have you a good copie of disk 7.1 for give me to try a new one the upgrade ?

Thanks a lot for your help.

Brgds, Maxquad

I have a horrible feeling you will get no further with the 6000 now. One of the operations during the upgrade is a wipe of the existing OS and once it is gone you are relying on the rebuild from the floppy disks to put the OS back on the machine so it will boot up again. With a crashed load I think you are highly unlikely to get it back. I don't actually know of a way to do it without removing the IC's which since Panasonic really don't deal with these things anymore it is highly unlikely you can put it back. The 6000 doesn't have a back up OS that can be loaded by pressing keys at start up. The machine is effectively empty. It is a set of PROM's all of which have to be in the right slot to load as an OS.

Hi Dave, thanks for your reply.

Have you an idea where I can find/download the good floppy disks of KN6000 OS7.1 ?

Thanks in advance

Big issue is if the OS on the 6500 is gone then there is no way for you to get the floppy to read and upload to the synth. The only way to do it I know of is to change the proms from the main board and to be honest you have to find some of them or someone that can blow your existing ones with copies not based on floppies but from original ics. I have a feeling that any upgrade done via floppy is liable to give the same sort of results as no matter where the OS source comes from across the internet I think they are all incorrect for these machines So once it is gone it is gone. There is no back up. It doesn't work like that. The machine needs the OS to start and part of the process to over write it is to delete the original so if it fails mid process there is nothing left for you to work with.
I have explained this before here. There is very little to be gained by changing the OS you would be far better to go and buy a more recent synth.

Hi ! I am not a expert on these issues but I always heard "go buy a more recent keyboard, or a synth " !
I have 2 Technics Keyboards. I have 3 Yamaha workstations. Never, never had such problems to upgrade or to update and I already installed several startup disks on them.
I have a KN 6000 with no data in the screen. I have power , the screen is lighted without any data on it and the floppy disk drive is green led light on.
No life from the keyboard. The last message I read from the screen was CPU error.
So, following your words : nothing to do, buy a new keyboard. Sorry but this can be happen with you brand.
I expected more from a brand which I already had 6 and I 2 keyboards now concerning to technical issues.
At least put them playing something would be nice.

You cannot do anything about this. It is a straight forward issue. You can only repair this situation with the technology that is out there by having another 6000 removing the eeproms, duplicating them on a eeprom duplicator and putting them back in your machine. There is NO OTHER SOLUTION! Without the operating system on the machine you cannot boot it to a floppy image and therefore you cannot re-write the OS back onto the machine. ALL the downloads that suggest that they are a valid upgrade are copies of a faulty piece of code and should NEVER EVER be used! For the sake of very minor upgrades do not be fooled into thinking that you are going to get a better machine by doing these so called upgrades. It is really not the thing to do.

Re: Need help to reinitialise my KN6000+EW65NX - looking for OS 7.1

OK ! Thks ! But let me ask you why Technics or Panasonic don't help these customers to get new EEPROMs or at least to get the data to
be burned into a new ones ?
Why force the client to get a second keyboard to dis solder the EEPROMs to do a copy of them ?
This is to force the client to get a new 7000 keyboard ?
Do you think sincerely that is the best way, the best policy to keep the brand on top reviews and get more clients ?
The keyboard 6000 is not a OLDER OLDER keyboard as you are saying. The KN 1400 SX or 701 OK, these are old.
I am no problem in to burn new EPPROMs if a have the data to do it. To get a 2nd keyboard, to convince the owner to let me do it that's the problem and if you
know that guy please tell me.
To me Technics, in the discontinued models should give the chance to replace the software in own machines.
Telling me "get a new car" because we don't have the electronic part for that one, is not be responsible.
One thing is sure : with the problem I have with the 6000 I'll never buy a 7000 from Technics.
Thanks for your help.

Re: Need help to reinitialise my KN6000+EW65NX - looking for OS 7.1

Firstly lets put a few thing straight. 1/ There is NO legal obligation for any product manufacturer to supply replace/spare parts for any item once production has stopped, this applies both in the UK and the EU. I cannot say what the law is outside these areas. 2/ The fact there may be some spare parts still in stock is good fortune, as many parts are outsourced from component suppliers who often produce a one off production run.
To relate to your post please note your keyboard is now 19 years old and Panasonic Technics stopped all Electronic Music Production in 2004. so any spares are now in the hands of specialist parts distributors, and the number of parts left is ever decreasing. Another thing is this problem not only applies to Technics but companies like Yamaha ( both musical and automotive diversions ) and larger companies Toyota,Ford, BMW, just to name a very few. Sadly Technics stopped making any form of musical instruments and have joined the ever longer list of well known names like GEM, Farfisa,Solina and even the likes of Hammond (USA) now in the hands of the Japanese as Suziki -Hammond. that have gone out of production or been taken over with no after-sales for older products
Sadly all of us are in the same boat, hoping our beloved instruments keep going that bit longed
Regards John..

OK thks by your attention and patience in your reply.
The only thing I can not accept is the fact we have a problem in a CPU and the brand can not give the data to flash a new one.
At same time avoid the user to use the floppy disk drive to pass any kind of programming.
Today you can have a very old computer but you can install any time new or old firmware on it without complications or you can get a new motherboard.
The electronic stuff as always lot of options to do it less here with keyboards.
Here you can not do nothing. You have to ask for a 2nd keyboard to copy the BIOS for a new EPROM. This is what I think incredible.
Only this I claim because I am forced to put this keyboard in the trash without any king scratches almost new only because I don't have the data to flash a new
5 Euros component.
Only this, John ! This turn me on crazy ! But what I can do against this ? Nothing ! And avoid to buy new Technics keyboards.
I hope sincerely that 7000 users don't have this usual 6000 CPU problems because I would like to know what would be the solution to them.
Best regards and thank you so much once again for your patience.

Re: Need help to reinitialise my KN6000+EW65NX - looking for OS 7.1

This keyboard is not like a computer but a dedicated piece of computer like hardware. It is the same as a computer without its BIOS eprom plugged in. You could not do anything without that as the BIOS is the low level part of the OS that then interfaces with the software to give you a complete working computer. Think of the BIOS in a computer as a set of basic pointers that tell the processor where to look for the boot partition for the operating system which then loads it to give you your lovely working PC. The KN6000 Keyboard is the same in that, once you have wiped the EEPROM (the BIOS) there is absolutely nothing that can be done to put it back. There is no support, floppy disk, or anything else to make this magically work as for the machine to find the code to write back to the EEPROM it has to read the EEPROM to get instructions to know where to look for its operating system to be able to read the floppy disk so basically it cannot and will not work. As I say the only way is to have either a new set of eeproms from the manufacturer which as you should be aware Technics has not made or supported any of its keyboards for best part of 28 years so there are none of those available, or to find an old working machine that you can have the eeproms professionally copied so think at least £150. Worse is I think the eeproms are soldered in in most of these keyboards and are thus not generally removable so add in another £100 to have them removed. I can't explain in any better than that. This is a fundamental failure of the low level code that makes the keyboard work and because of that it is now worthless scrap. This is NOT Technics fault. It was a straight forward facility to allow for updates for keyboards capable of doing more when additional cards were added to the machine. It wasn't intended to allow people just randomly to keep upgrading in the hope of getting something for nothing.
