All about the Roland Jupiter-series

Hello list,
Nice having a list about the jupiter series especially the jp-8 :))
I have some qeustions:
what are the serials of the last made jupiter-8's, not exactly but 
acoording to the beginning numbers.
(that of the service manual i already know)

Isn't there a nice story about the design/production of the jp-8?
sos article sucks, i only know mr Yamabusha (spelled wrong..?) was on 
the design team, on the web you can read nice design stories of 
emu/prophet etc, but no jp-8, so please share your knowlegde about 
the design, myths/reality all are welcome :))
Bye!
