SCSI-Zip250_Project
IT WORKS! Well enough anyway! [

A couple more pictures of the Winstation WFS7E5W13 and unacceptable results I had with this pair of drives in older Macs are there in the five year old thread. This one shows the business end of the adapter board and its carrier:

Tested it under 8.1 as I was rebuilding what's left of my 9500 because I noticed that the CD-ROM was a SCSI-2 device and SCSI-2 was enabled. I got a different result from the eject command. On the Mac Plus and Radius 81/110, the system hung dead as a doornail when I tried to eject the disk. That led me to believe that Deep in the dismount process thing went way bad. Playing around with it on the 9500 I came up with a workaround for the new problems where I'd failed in those earlier attempts.
Now when I "eject" the mounted, perfectly usable usable Zip250 cart, it doesn't eject, but it does "dismount!" However it remains in the drive producing the dreaded Unreadable Disk/Eject/Initialize dialog box. Hitting eject repeatedly in the window gives the same result. But by bopping the manual eject button on the drive while in the Eject/Initialize window the cart pops it right out, none the worse for the wear. Then issuing the eject command from the Eject/Initialize window completes the dismount/eject sequence and the 9500 remains up and running where the others had bombed.
I'm happy for now. At some point I'll probably play with it some more to see where in the Hardware/OS progression its behavior changes. I'm running off the inner black SCSI connector, the white one that points straight up doesn't appear to be functional. Are both SCSI-2 Spec with one or the other being Fast SCSI-2? Dunno which is which offhand. :-/
