roland DXY plotters

[n00dle0]

Hi!

I am desperately looking for the specs for the vintage Roland DXY
series plotters. What are the difference between DXY-880 and DXY-885?
Or the difference between DXY-980 and DXY-990? Also the specs for
1100/1200/1300 would be helpful? I just can't find any information on
the net. If you have manuals for these devices could you please share
their specs. Any other pointers to find this information would be
appreciated.

Thanks,
Ash
