IBM PC Series

The IBM PC Series personal computer was the follow-on to the IBM PS/ValuePoint and IBM Personal System/2. Announced in October 1994 and withdrawn in October 2000, it was replaced by the IBM NetVista, apart from the Pentium Pro-based PC360 and PC365, which were replaced by the IBM IntelliStation.

The PC 100 was a budget model, available only in selected markets.

The PC 140 was a budget model, available only in selected markets.

Industry standard ISA/PCI architecture, first IBM machines with USB. Processors ranged from the 486DX2-50, 486SX-20, 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. Within the 300 series the following models appeared:

Its last sub model used the Pentium P54C processor clocked at 100, 133 or 166 MHz. It had, depending on the sub-model up to 4 ISA and/or 3 PCI expansion slots and four (2 external 5.25 inch, 1 external and 1 internal 3.5 inch) drive bays. It had in its latest version, the 6577, 1 DIMM-168 and 4 SIMM-72 RAM slots, and featured an IBM SurePath BIOS. This PC has 2 USB 1.0 slots in the back. The latest operating system which can be installed in this PC is Windows 2000 or Windows ME. Windows XP can be installed, but the speed will be much slower than Windows 2000 or Windows ME, and it is nearly unoperable with Windows XP.

It comes with an 5 volt SDRAM slot which is not compatible with the 3.3V (the common used SDRAM). The slot looks same, but the keying is different. Trying to push a 3.3V SDRAM on the 5V SDRAM slot could make the slot faulty and/or broken RAM chips.
