DECtape II was introduced around 1978 and has a similar block structure, but uses a much smaller 0.150 in (3.8 mm) tape [25] (the same width as an audio compact cassette). The tape is packaged in a special, pre-formatted DC150 miniature cartridge consisting of a clear plastic cover mounted on a textured aluminum plate.

DECtape II was a low-cost, low-performance random access magnetic tape secondary storage system, proprietary to DEC.They were effectively a successor to the earlier DECtape.. They were primarily intended for booting and software distribution (although they could be used for mass storage), so in some sense they were an early alterative to floppy disks.. It used a DC-100A cartridge from 3M ...

Digital Equipment TU58 DECtape II emulation with a microcontroller and a SD-card. The emulator was developed using open soure hardware and software components.

The TU58 DECtape II magnetic tape drive used the DECtape-II cartridge, which could hold 256KB. A TU58 unit contained one or two drives, but with two, only one could be operated at a time. It was available in both a standalone case (suitable for desktop usage, or mounting in a 19" rack), or as a bare unit (for mounting in some other unit); in …

The Digital Equipment TU56 DECtape is the “classic” DEC minicomputer tape drive. It is block addressable, just like a disk drive. It contains 10 tracks – 5 tracks with 100% redundancy- a data timing track, a “mark” track and three data tracks. ... I have several TU58 DECtape II drive mechanisms and controller boards in my collection ...

A VAX-11/780. The VAX-11 is a discontinued family of 32-bit superminicomputers, running the Virtual Address eXtension (VAX) instruction set architecture (ISA), developed and manufactured by Digital Equipment Corporation (DEC). Development began in 1976. In addition to being powerful machines in their own right, they also offer the additional ability to run user mode PDP-11 code (thus the -11 ...

The TU58 DECtape II is a low-cost, mass storage device which may be used for a wide variety of applications. This Manual provides the information that a user needs to install, interface, and command the operation of the tape system.

The software emulates an TU58 DECtape II, which is controlled by the PDP over serial RS232 line. The "tape content" appears as plain files in a shared directory, and can be accessed on both sides. So you can easily exchange files between PDP-11 and your host, just by copying to and from the shared directory, even per drag'n drop.
