there is no such thing as an upgrade for the DSP4000 to DSP4500. There was a PCMCIA “Alchemy 101” Card coming with Eproms V2.300 that added the last collection of Vsig modules and presets to a 4000, developed for the 4500.
Also, the 4500 came standard with a sampler board which the 4000 didn’t have. So a 4000 “upgraded” to 4500 would require sampler card + Alchemy Card + V2.300 EPROMs.
Another VERY important detail is that the 4500 didn’t have EPROMS as it was the first Eventide using flash memory… so things get almost impossible.
