Hi Siegfried! I just got a DSP4000 that I hope to fix, and I’m really interested in upgrading it now that I have it apart and am messing with it.
Where and how did you get a 4000 upgraded to 4500? Did you have it upgraded yourself or by a tech? I’d love to get in touch with someone who could give me the dumps of the EPROMs for the 4500 so I could do such an upgrade on mine, I have an EPROM burner. I’d, of course, pay for the images. I think the 4500 has a lot more presets (and hence EPROMs) than the DSP4000, so I’d need dumps of all of them. Do you maybe have a pic of the insides of the device?
Thank you very much!
