The Vintage Computer Festival last weekend featured racks and racks of old
minicomputers, enough terminals for an entire lab, and enough ancient storage
devices to save a YouTube video. These storage devices – hard disks, tape
readers, and 8″ disk drives – were only connected to vintage hardware, with one
exception: a DEC RL02 drive connected to a modern laptop via USB[1].

The DEC RL02 drive is the closest you’re going to get to a modern mechanical
hard drive with these old machines. It’s a huge rack unit with removable
platters that can hold 10 Megabytes of storage. [Chris] found one of these old
drives and because he wanted to get into FPGA development, decided to create a
USB adapter for this huge, old drive.

The hardware isn’t too terribly complex, with a microcontroller and an FPGA
that exposes the contents of the drive over USB mass storage. For anyone trying
to bootstrap a PDP-11 or -8 system, [Chris] could download disk images from the
Internet, write them to the disk, and load up the contents of the drive from
the minicomputer. Now, he’s using it with SimH[2] to have a physical drive for
an emulated system, but the controller really doesn’t care about what format
the disk pack is in. If [Chris] formatted a disk pack with a FAT file system,
he would have the world’s largest and heaviest USB thumb drive in the world.

Video below.
