Iomega Bernoulli Box 20+20 (A220H)

Ok, some small progress. The 5.25" Bernoulli Box II (20MB) is working. I have a newer set of software (RCD v4.7), DOS 2.1, and the Iomega PC2B-50 interface card all running in an XT. My previous problem is that the newer drive didn't like the older Iomega software I was using. As an aside, the newer version of the software doesn't work under DOS 5. I think they claim to support only DOS 2.x and 3.x. I'm in the market for any newer version of the Iomega software for a Bernoulli box is somebody has a it stashed somewhere. The newer software looks like it works with the older 8" drives - the diagnostic program recognizes the drive. But my 10MB carts are not recognized by the drive - it spins them up, and then spins them down. All of the Iomega software reports that the drive is not ready. This is baffling to me because under Linux they were spinning up and staying online. (I'll have to move back to a Linux box again to verify that nothing has broken.) That box really needs a 20MB cartridge to prove that it works. But it's close. If anybody wants the RCD v4.7 drivers give me a shout off-list. Regards, Mike
