The world's largest USB-drive
Visitors festival retro computers in New Jersey saw a lot of nostalgia and amazing exhibits. Alone storage devices were so many that they could save a movie to MP4.
Among the drives are represented ancient HDD, tapes, 8-inch floppy disk. All are only compatible with the old equipment. With one exception: it drive DEC RL02 a >, which is connected to the modern computer by USB!
External Drive DEC RL02 worked with computers PDP-11 and PDP-8. Box weighing 34 kg in 70 years positioned as ultra-compact and portable device. But today it is the largest and heaviest in the world of portable USB-drive.
The information is stored in the cartridge with the plates 10, 4 megabytes. U disk exceptionally high performance for its time: the average search time - 55 milliseconds, the maximum - 100 milliseconds. Information is transmitted at a rate of 250 kilobytes per second sequential read.
Engineer Christopher Parish (Christopher Parish) developed a microcontroller to the FPGA to connect to a computer DEC RL02 and recognition as a device USB Mass Storage, so now he can always take to the road compact «USB-stick" to 34 kilograms. Not disappear as good: drive as much as 10 MB.
Circuit boards and other project documentation Christopher published on Github .
