Modular G1 freezing at startup - EPROM Damage? Subject description: Is there a way to reflash firmware on 27C040 |
|
|
Hi, I own a modular G1 since ~1999 and it's not booting anymore. Some of the lights go on, Display is illuminated and shows a couple of lighted bars on top...
Since we checked for the really obvious, like PSU etc, I found that there is a 27C040 Eprom inside, with a lable "Ver 1.10" on top. I had two updates a couple of years ago, though.. I can't tell, but I suspect the EPROM programming to maybe have "faded", something that is said to happen with this kind of UV-erasable cmos EPROMS sometimes.
If there's an easy way to reflash firmware to this chip, I would be very glad to try this out. As said, it doesn't boot now and is not recognized by the editor at all.
Any ideas? I don't plan to send it somewhere and wait for months to get it back We're quite used to repairing our stuff ourselfes... And there's a major project in may we would need the Nord for.
Used prices are MUCH too high at the moment, otherwise that would have been another possibility
Thanks! best |

It has been a while since I looked at it .. but I think:
The EPROM just holds the boot loader - not the OS. The OS is in flash memory and that one is more likely to have faded.
Did you try if the OS update tool still recognizes it?
to download: http://www.nordkeyboards.com/downloads/legacy/nord-modular
Just unzip and run the updater and it will guide you the thing seems to still work on win 8.1 ... although when I quit it halfway (as I had no intention to upgrade) it would hang ... _________________ Jan
also .. could someone please turn down the thermostat a bit.

I'm afraid it doesn't work. The problem is, it's not even getting to the start screen! It's supposed to go in update mode if shift/store buttons are pressed during power up, but it doesn't. Only the lights go on. Nord could not be found.
I suspect it could well be the bootloader...
We are stuck now. I am thinking about buying a used one, I really need this synth, since there's nothing comparable on the market, as it seems.
And I have years of experience and tons of patches for the nord.
And working with software synths is not an option, for many reasons.
Any experience with repairs of Nord stuff? I don't think too much of Nords support policy, as they have rather immediately dropped support for the G1 editor as soon as they released the G2...
And a working OSx version was announced, too, but then they just didn't bother. |

* bump *
Since it seems I don't get an answer from Nord's support department:
Anyone knows if there's a way to get this chip including the boot loader? Or just the software, to try and put it to a new 27C040?
It says Ver.1.10.
I would like to get my beloved Nord modular back to life, there seems to be no product on the market to replace it, and used modulars are expensive.
Any help or idea would be very much appreciated!
Cheers,
Richard |

Thanks!
As I need it fast for an important project that is ahead, I went the easy road and bought a used one for 500€
Don't know how much repair would cost, but I expect it to be not so much less, including two times shipping etc. So it's a good deal, and now I have spare parts for the time to come.
Still interested what the problem was. I will check out the forum soon.
Cheers, Richard |
