I have a DoubleUp board from Sigma. It works very well and very quickly. I now keep all of my infrequently used software compressed and pay very little penalty (in terms of time) when I do want to use it. It works as another method of compression under DiskDoubler (you have a choice of different compression methods and "DoubleUp board" is one of the ones listed). All in all, a very smooth implementation. On the other hand, the version of DiskDoubler that was/is(?) shipping with the DoubleUp board is 3.2. This is only partially compatible with system 7.0. What I mean by partially is that the INIT portion (the part that tosses a "DD" menu onto your menu bar) does not work. Reportedly everything else does. I have not tried it with 7.0 yet, and am waiting until the hub-bub dies down a little before making the move from 6.07->7.0. There is a new version of DiskDoubler (3.7) that has a shipping date of June 1st (I think) which will be completely compatible with System 7.0. Does anyone know if people that got DiskDoubler as a part of their purchase of the DoubleUp board are eligible for the free upgrade to 3.7 as are regular purchasers of DiskDoubler? (the upgrade is supposedly free for those that bought the software after a certain date in April ... I forget when exactly). --Brad
