Magnasee is a product used to visualize the magnetic fields recorded onto magnetic recording media such as magnetic tape, diskettes, and the like.

An upgraded version, the NC200, appeared in late 1993, featuring a 3.5" floppy disk drive able to read/write MS-DOS-formatted double density disks, 128 KB RAM, some extra software - most notably a spreadsheet and three Tetris-like games - and a larger, backlit screen.
The machine's hardware consisted of a 9 inch (229 mm) black-and-white monitor, a single 3½ inch 256 KB floppy disk drive and an IBM Selectric-compatible keyboard.
The Commodore 8280 were dual unit 8" floppy disk drives for Commodore International computers.
Commodore released a high-speed floppy disk drive for the Plus/4, the Commodore 1551, which offered much better performance than the C64/1541 combination because it used a parallel interface rather than a serial bus.
Offering either magnetic tape or diskette storage, the Model 1 could store as much as 204,000 bytes of information per tape cartridge or 1.2 million bytes on a single diskette; the Model 2 allowed only diskette storage.
It replaced the 16 MHz Motorola 68020 CPU and 68881 FPU of the II with a 68030 CPU and 68882 FPU (running at the same clock speed); and the 800 KB floppy drive with the 1.44 MB SuperDrive (in fact, it was the first Mac to have one).
For much of the early 1990s, the Gamesampler, a subset of the Entertainment Pack small enough to fit on a single high-density disk, was shipped as a free eleventh disk added to a ten-pack of Verbatim blank 3.5" microfloppy diskettes. Games on the sampler included Jezzball, Rodent's Revenge, Tetris, and Skifree. A "Best of" disk of several of the games was also available at times as a mail-in premium from Kellogg's cereals.
Distributed on floppy disk, the program is divided into several menus that allows one to access the data.
Users also had the option of paying $9.95 USD plus tax (for US residents) or $14.95 CAD plus tax (for Canadian residents) for CD-ROM or 3.5" floppy disk media along with a hard copy user's manual during that promotional period. This was requested either through a promotional mail-in card (was distributed in stores) or calling Microsoft directly. The freely downloaded (moneyweb.exe) version was the same as the paid 3.5" floppy disk version but no user's manual was available.
The Philips NMS-8250, (NMS is short for "New Media Systems") was a professional MSX 2 home computer for the high end market, with two built in floppy disk drives in a "pizza box" configuration.
NTLDR is typically run from the primary hard disk drive, but it can also run from portable storage devices such as a CD-ROM, USB flash drive, or floppy disk.
For personal computers, this size is used today in floppy-disk-drive cables and older or custom Parallel ATA cables.
Chipset: In addition to the Z80 and 6502, the system also included Intel 8255A PIO, Intel 8251A USART, Intel 8214 Programmable Interrupt Controller, Motorola 6845 CRT controller, Western Digital 1793 floppy disk controller, and OKI MSM5832 real time clock.
