DREM – MFM/RLL hard drive and Floppy emulator

Connecting old floppy disk drives to modern hardware is not easy. Resurrecting old MFM and RLL hard drives is even harder. The primary method would simply be to get an old PC with the legacy hardware to read the hard drives. But now there’s DREM.

DREM is based on the high performance FPGA platform and does not require the use of a PC for any file encoding operations. DREM is equipped with an VGA output, PS/2 keyboard input and file manager software. A user can browse the SD card and insert DSK images into virtual drives.

DREM uses DSK disk image files, which contain the raw dump of a disk. The raw image consists of a sector-by-sector binary copy of the source medium.

If you’re just looking for floppy emulation, I recommend GreaseWeazle or other solutions.

Also available, but doesn’t seem quite as well baked, is the pdp8online MFM board emulator.
