I'll take a look at my records at home (I don't have these old documents in
the company). But I'm about to leave for a music fair for 5 days ("My Music"
in Friedrichshafen/Germany). The A-100 is shown within the synthesizer
vintage exhibition. Please send me a reminder directly to my email address
next week.

Best wishes
Dieter Doepfer
