Ahh Steve, one word. Helicopter. 1988,89,90. Worked on Cue-List and MFX1 console.

Anyway, one IIx is working well. Do you know of any FCNs for IIx that brought Rev2 CMI-01As up to Rev3/4? I'm reverse engineering one now. It's going quite well. Built a daughter card to hold the SSM2045. Fewer parts than the CEM3320 based one. Quentin's re-do was nicely modular in that regard.

Best,

Joe
