Yellowstone Universal Disk Controller Now Available

Big Mess O’ Wires (BMOW) has begun selling their new Apple II-series universal disk controller card, the Yellowstone Universal Disk Controller.

Yellowstone is a new disk controller card that can be used by retro computing enthusiasts in their Apple II-series machines, including Apple and clone machines, with an array of 5.25-inch and 3.5-inch disk drives from the 1980s. Further, Yellowstone also supports BMOW’s own Floppy Emu disk emulator and naked Macintosh 800k and 1.44MB drives.

Yellowstone is a universal disk controller card for Apple II computers. It supports nearly every type of Apple disk drive ever made, including standard 3.5-inch drives, 5.25-inch drives, smart drives like the Unidisk 3.5 and the BMOW Floppy Emu’s smartport hard disk, and even Macintosh 3.5-inch drives. Yellowstone combines the power of an Apple 3.5 Disk Controller Card, a standard 5.25-inch (Disk II) controller card, the Apple Liron controller, and more, all in a single card.

I am excited to have received my Yellowstone card this week because I also received a second unenhanced Apple //e. (Have I mentioned that I have a deep fondness for my first Apple computer?) I plan on using the Yellowstone card in one of my //e’s as a way to get 3.5-inch disk drive support since finding new old stock 5.25-inch floppy disks is a bit difficult.

I ended up ordering the “Everything Bundle” ($169). This bundle, as the name implies, includes the Yellowstone universal disk controller card ($139) and two DB-19 female disk adapters ($19/ea) so that I can connect two sets of drives to a single computer at a time.

My end result could look something like an enhanced Apple //e with the DuoDrive and the BMOW Floppy Emu connected for easy image-to-floppy creation or to archive the original floppies in my small collection. Another configuration that I am looking forward to trying is connecting my Apple 5.25″ drive and a Macintosh 800k floppy drive to the same system to make a bootable floppy disk with a few different programs on it.

And that is what makes these new cards for old computers so interesting – you can mix-n-match new and old parts to extend and customize the Apple II-line just like Woz intended.
