WOW George, that's an answer... I'll need more time to digest it than you eating my Homemade pie!

I am taking things out of the boxes one by one. Now I am 'resurrecting' a DSP5000C and a 568.2. where I found a sloppy disk! A floppy! where I can find a floppy disc equipped PC today? I am lucky it's a 3 inches and not a 5 1/4!
G91 probably was connected as player only to the G68. Yes, probably the G68J is the good one but at this point do I have to change type for DSP5K from 5 as it is now to 1 suppose.
Now I am opening the system slowly, selecting only few parts. I’m probably going to connect the G68 and after this I let you know what happened.
THANKS!

PS Is what you are saying that speaker menu are available not only directly but also using a processor?
Maybe I have a firmware version that locks the menu system directly from the speakers... it's 5.040 and I remember this version is related to 24/96 version of DSP5K.
