TurboDOS

It went for $31, but shipping was double that. The only problem is it wants a login and I haven't guessed one in 10 minutes of trying. Thankfully, it tells you if the user name is wrong before it even gets to a password so that the brute force approach is perhaps tractable. My understanding is that turbodos stores the password file in plaintext, so another way to skin the cat would be to find a way to dump the disk. It is a Rodime RO 200, 10.5 MB model. This drive uses an ST406 type of interface, but IMS mounted some type of adapter board on the rear of the drive, and the disk controller plugs into this adaptor via a 40 pin ribbon cable. This system is configured with the 10.5 MB hard disk and controller that I just mentioned, plus a floppy disk controller and floppy (5.25" TEAC FC-55F), a 64 KB parity checked DRAM board, the master Z80 processor, and two slave processors (Z80 + 64 KB parity checked DRAM each). I've spent some time doing floppy disk recovery with IMD and catweasel tools, but I haven't messed with hard drives. Any recommendations on the best to dump the disk image? Thanks.
