To be more precise, the 4500 FW used flash memory chips on which the software for the effects was stored. What’s needed is a working, programmed flash memory chip from which the 4500’s software can be copied. The software can then be installed (‘flashed’) on other 4500s whose flash chips were inadvertently cleared. Eventide discarded all its copies of its own old software when they superseded the 4500 with new models. If anyone has a working 4500, please please please respond so that we can resurrect this valuable, irreplaceable gem.

For those wondering how the chip got cleared, it seems that in the old days Eventide had a key sequence that could clear the chip so that they could re-program it if it wasn’t working properly… back when they still had the code to re-program it.
