to read the Job Control Language cards that defined the stack of jobs to run and to read in transaction data such as customer payments. The operating system was held on tape or disk, and results could also be stored on the tapes or hard drives. Stacked job processing became an exciting possibility for the small but adventurous computer user. A little-known and little-used suite of 80-column punched-card utility programs known as Basic Programming Support (BPS) (jocularly: Barely Programming Support), a precursor of TOS, was available for smaller systems. Component names IBM created a new naming system for the new components created for System/360, although well-known old names, like IBM 1403 and IBM 1052, were retained. In this new naming system, components were given four-digit numbers starting with 2. The second digit described the type of component, as follows: Peripherals IBM developed a new family of peripheral equipment for System/360, carrying over a few from its older 1400 series. Interfaces were standardized, allowing greater flexibility to mix and match processors, controllers and peripherals than in the earlier product lines. In addition, System/360 computers could use certain peripherals that were originally developed for earlier computers. These earlier peripherals used a different numbering system, such as the IBM 1403 chain printer. The 1403, an extremely reliable device that had already earned a reputation as a workhorse, was sold as the 1403-N1 when adapted for the System/360. Also available were optical character recognition (OCR) readers IBM 1287 and IBM 1288 which could read Alpha Numeric (A/N) and Numeric Hand Printed (NHP/NHW) Characters from Cashier's rolls of tape to full legal size pages. At the time this was done with very large optical/logic readers. Software was too slow and expensive at that time. Models 65 and below sold with an IBM 1052-7 as the console typewriter. The 360/85 with feature 5450 uses a display console that was not compatible with anything else in the line; the later 3066 console for the 370/165 and 370/168 use the same basic display design as the 360/85. The IBM System/360 models 91 and 195 use a graphical display similar to the IBM 2250 as their primary console. Additional operator consoles were also available. Certain high-end machines could optionally be purchased with a 2250 graphical display, costing upwards of US $100,000; smaller machines could use the less expensive 2260 display or later the 3270.
