well, This 5160 Personal Computer XT (eXTended) came equipped from IBM with lots of good stuff, including 256k RAM on the motherboard, plus a 256k RAM expansion card (with "flipchip" IBM 64k x 8 chips), an asynchronous communications port, one 5.25" full height IBM 360k floppy drive, a 10m IBM (Seagate ST-506)) hard drive, and a Color Graphics Adapter driving an IBM 5153 color monitor, plus the Monochrome Display Adapter, which also drives the printer. I have the original IBM Guide to Operations, which includes the diagnostics disk, and a cool "getting to know your IBM PC" educational disk. This one has IBM DOS 2.10 (1984) loaded on the hard drive. This computer does NOT have a real time clock, you must enter the time and date every time you boot it up. I have an AST Six Pack Plus memory/clock/comm/gameport board, with the software and manual, but I don't want to put any non-IBM cards in this computer, as it is just too original to mess with.
Some differences between the PC and XT include the type of power supply originally included--63 vs 135 watts; the number and spacing of expansion slots--5 vs 8; the PC has a cassette tape interface connector on the back, if you couldn't afford to order the floppy with it...drives were expensive back in August, 1981, when it was introduced. The XT came standard with the 10m drive, but it cost close to $6000 (configured like this one) when introduced in 1983. I bought the XT computer used 15 years later for $8.

z/OS is designed to deliver the highest qualities of service for enterprise transactions and data, and extends these qualities to new applications using the latest software technologies. It offers a highly secure, scalable, high performance base on which to deploy SOA-enabled applications using Internet and Java™ technologies, designed to provide a comprehensive and diverse application execution environment coupled with a highly secure and resilient enterprise data store. z/OS.e V1.8 is the last release of z/OS.e. It is no longer orderable. IBM plans to withdraw service for z/OS.e V1.8 in September 2009.

Linux on System z
Linux on System z combines the advantages of the IBM mainframes with the flexibility and open standards of the Linux operating systems. Linux can play a major role in the simplification of the IT infrastructure—not only because it helps simplify business integration through the use of open and industry standards, but also because it supports deployment of new solutions more quickly and accelerates time to market.

z/VM
The z/VM hypervisor is designed to help clients extend the business value of mainframe technology across the enterprise by integrating applications and data while providing exceptional levels of availability, security and operational ease. z/VM virtualization technology is designed to allow the capability for clients to run hundreds to thousands of Linux servers on a single mainframe running with other System z operating systems, such as z/OS®, or as a large-scale Linux-only enterprise server solution. z/VM V5.3 can also help to enhance productivity by hosting non-Linux workloads such as z/OS, z/VSE™ and z/TPF.

TPF
TPF remains the "high volume transaction processing" (HVTP) platform of choice for many of IBM's largest customers for many years. These customers cover several industries, including airlines, lodging, finance, health, and travel.

z/VSE
z/VSE, the follow-on product for customers with VSE/ESA installed, is designed to exploit selected IBM System z and IBM Systems Storage technology and help address the needs of VSE clients. z/VSE continues the focus on interoperability.
