Bus and tag cables. Bus and Tag is an "IBM standard for a computer peripheral interface", [1] and was commonly used to connect their mainframe computers to peripheral devices such as line printers, disk storage, magnetic tape drives and IBM 3270 display controllers.
ESCON cable with connectors. ESCON (Enterprise Systems Connection) is a data connection created by IBM, and is commonly used to connect their mainframe computers to peripheral devices such as disk storage, tape drives and IBM 3270 display controllers.
FICON and its predecessors are the only protocols sufficient to communicate with traditional mainframe peripheral devices, especially for z/OS. However, most [dubious – discuss] mainframe operating systems also support FCP (SCSI command set over Fibre Channel). FICON is technically quite similar to more popular storage protocols, such as FCP.

Since the late 1950s, [NB 3] mainframe designs have included subsidiary hardware [NB 4] (called channels or peripheral processors) which manage the I/O devices, leaving the CPU free to deal only with high-speed memory. It is common in mainframe shops to deal with massive databases and files. Gigabyte to terabyte-size record files are not ...
Uniscope was a registered trade mark for a set of Sperry Univac dumb terminal products. The trademark was applied for October 13, 1969. Several models were produced: the Uniscope 100, Uniscope 200, Uniscope 300, the UTS 400, the UTS 10, the UTS 20, the UTS 30, the UTS 40 and the color UTS 60.
A direct-access storage device (DASD) (pronounced / ˈ d æ z d iː /) is a secondary storage device in which "each physical record has a discrete location and a unique address". The term was coined by IBM to describe devices that allowed random access to data, the main examples being drum memory and hard disk drives . [ 1 ]
The IBM 3704 was an entry-level version of the 3705. It was restricted to 26 half duplex lines (assuming Type 2 Scanner). DMA devices were not supported on the 3704. Performance was about the same as a 3705-I. A 4704 (a 3704-compatible device) was planned, but was never introduced.
