modular G1 ROM image

[Jasxon]

Hi everyone,

I’m still (well, getting back into) diagnosing my boot issues with my G1.
I have ordered some new EPROMs and will program them.
I’m hoping that someone here has a dump of the EPROM or knows where to get one.
Any help would be greatly appreciated.

Kind regards,
Jasxon

Hi Jasxon,

I turned on my Modular today and it doesn't boot. LCD screen lights up and after a while a few LEDS lit up too, but that hasn't repeated itself on subsequent power-ons - just a glowing LCD screen.

Just wondering how you got on with your issues ?

From reading around (and not being an expert) I can only guess (a) some issue with the boot loader from the EPROM, which could be (a) some degradation of the EPROM itself or (b) an issue with the power supply reaching pin 32 of the EPRom (should be 4.5-5.5v for a 10% tolerance chip, or +4.75-5.25v for a 5% tolerance chip). If its a power supply issue, most likely culprit would be issue with the capacitors.

I'll be poking around inside my unit today and will let you know what I find...

However, as a hep to the wider community, if someone could do an EPROM bin file dump of anything from v1.01 to v3.03 that would enable replacement of faulty EPROMs, that would be amazing.

A few years late here, but here's a dump of the Nord Modular G1 Rack. EPROM is labeled Ver 3.03.

I’ll be trying to recover my G1 this week with a new EPROM. I’ll let you know how it goes. Thanks for the .bin file.

Hi Inspector Jester,

I just brought my G1 back from the land of the dead thanks to your .bin file! Everything works fine except for a few things — I have the keys version, not the rack, so maybe that’s the reason?

Would you be so kind, if you have it, to share the G1 keys .bin file with me? The only issue I’m having is that the octave selector lights aren’t working, but apart from that, everything else is perfect.

You definitely made me happy, dude — the G1 is one of the centerpieces of my music.

Thanks a lot!

Hello, I am sorry to say that I only have the rack bin file and I only own a G1 Rack.

Thanks for the reply, I’ve only just seen this. I’ll have a go with this file, but I also have a keys version, not a rack.
Many thanks! I’ll report back when I get a chance to attempt to plan to flash a new chip.
Kind regards,
Jasxon
