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.
