I picked up a dual reverb card for my Lexicon PCM 90 but can't use it as my pcm90 has V1.00 ROM and the card requires a unit with the later ROM v1.01.

On the off chance anyone has a PCM 90 v1.01 and wants the extra algorithms and presets shoot me an email.

I looked for one on and off for a couple years before finding this one, paid 160 bucks only to find I'm (as Bugs Bunny would say) "a maroon".
