A friend of mine told me that the siquest removable media HD will not work on a n A3000. Is this true? Is it because of the reselect problem? Is it the driver? Any help will be apprichated. -- Amiga@ccwf.cc.utexas.edu .....Paul...... Listen to what I mean, not what I say.

Oops... you are right. The 2090 _does_ use a WD 33C93. -larry -- The only things to survive a nuclear war will be cockroaches and IBM PCs. +-----------------------------------------------------------------------+ | // Larry Phillips | | \X/ lphillips@lpami.wimsey.bc.ca -or- uunet!van-bc!lpami!lphillips | | COMPUSERVE: 76703,4322 -or- 76703.4322@compuserve.com | +-----------------------------------------------------------------------+
