SIMH images to Zip Disks

The earlier Zip drives shipped with an ISA card and some of the later drives had a PCI card. All the Jaz cartridge drives that I used that included an interface card all had a PCI card but apparently they had some with ISA cards as well. The later external USB Zip drives could also make use an optional Firewire/1394 interface module accessory. At one time I made heavy use of both the 100MB and 250MB Zip disks and 1GB and 2GB Jaz cartridges for disk image backups. I had only one failure of a 1GB Jaz cartridge and that was due to the metal tab on the shutter breaking. They were used in a relatively dust free environment though, which I'm sure had something to do with it. I do distinctly remember Jaz drives needing a BIOS update from a Windows 95 computer prior to use with a non-Windows OS in order to properly deal with Tagged Command Queuing. The drives themselves didn't support TCQ (or at least not properly) but the earlier BIOS versions would happily agree to use it, which of course caused all sorts of havoc with higher end SCSI cards. IIRC some drives also needed to be pre-configured with a Windows-only software utility to enable support for disconnect-reconnect (although now that I'm thinking about it, I may be thinking about a different drive). Here is an example of what these drives would do if the BIOS wasn't updated so that the drive would decline to use TCQ: http://groups.google.com/group/linux.dev.scsi/tree/browse_frm/month/1996-11…
