Re: Nikon 8000 fluid mount 120 glass carrier

["Ernst Dinkla" <E.Dinkla@xxxxxxxxx>]

Strange, my Alpha 300XL with W2000pro special crashed while
sending this first message yesterday. The message wasn't in the
sent items box nor did I get the scan.leben list return. So I
wrote another message. Time to replace that nice computer, it
makes too much noise too.

Yes, I will put a picture on the net this afternoon. Maybe
followed by a PDF with more details in the weekend.
Commercialising of DIM gadgets isn't my forte. One dissatisfied
user of the 8 CIS Epson 9000 CIS systems I installed spoiled my
appetite for that kind of work. It would be nicer if Nikon who
probably follows this list picks up the concept. Epson followed
the 9000 list messages and got an answer to our complaints and
picked up our solutions where appropriate: result the 7600/9600.
Not my CIS system though while 5 Japanese Epson people saw that
solution in Amsterdam. It didn't fit their Gillette type of
marketing :-)
