The HandBook 486 also has a pointing device similar to the IBM trackpoint located on the right hand side of the keyboard just above the enter key. The Gateway HandBook remains one of the smallest laptops ever produced and was a precursor to Netbooks such as the Asus Eee PC , the Dell Inspiron Mini Series , and the Acer Aspire One .
The Intel 486, officially named i486 and also known as 80486, is a microprocessor introduced in 1989. It is a higher-performance follow-up to the Intel 386 . It represents the fourth generation of binary compatible CPUs following the 8086 of 1978, the Intel 80286 of 1982, and 1985's i386 .
The Pentium (also referred to as the i586 or P5 Pentium) is a microprocessor introduced by Intel on March 22, 1993. It is the first CPU using the Pentium brand. [3] [4] Considered the fifth generation in the x86 (8086) compatible line of processors, [5] succeeding the i486, its implementation and microarchitecture was internally called P5.
Industry standard ISA/PCI architecture, [1] first IBM machines with USB.Processors ranged from the 486DX2-50, 486SX-25, 486DX4-100 to the Pentium 200 and in case of the Models 360 and 365 the Pentium Pro. 486 models had a selectable bus architecture (SelectaBus) through a replaceable riser-card, offering the choice of either VESA Local Bus/ISA or PCI/ISA.
Pentium OverDrive for 486 systems Die shot of Pentium OverDrive for 486 systems The Pentium OverDrive is a heavily modified, 3.3 volt Pentium P54 core manufactured on 0.6 micrometer technology. It is fitted with a 486-compatible bus unit (though with an increased pin-count), an integrated heatsink and fan, and 32 kB of level 1 cache , double ...
80486SL. The Intel i486SL is the power-saving variant of the i486DX microprocessor. [1] The SL was designed for use in mobile computers. It was produced between November 1992 and June 1993.
The ODPR chips had 168 pins and functioned as complete swap-out replacements for existing chips, whereas the ODP chips had an extra 169th pin, and were used for inserting into a special 'Overdrive' socket on some 486 boards, which would disable the existing CPU without needing to remove it (in case that the existing CPU is surface-mounted). ODP ...
MIL-STD-498 standard describes the development and documentation in terms of 22 Data Item Descriptions (DIDs), which were standardized documents for recording the results of each the development and support processes, for example, the Software Design Description DID was the standard format for the results of the software design process.
