The IBM PC Series 300 is the range of IBM business desktops sold under the IBM PC Series name between 1994 and 2000. The PC Series was announced in October 1994 as the successor to the PS/ValuePoint and withdrawn in October 2000, when IBM NetVista replaced it.[1][2] The first machines carried model names (PC 330, 340, 350, 360 and 365); from 1997 the range was sold as the PC 300GL, PC 300PL and PC 300XL, and in 2000 simply as the PC 300.[2] The PC Series 700 was the higher-end range sold alongside it.[3]

IBM's machine type numbers for the 300 Series begin 65 or 62; in IBM's scheme the first two digits identify the commercial desktop series (65 for 300, 68 for 700), the third the number of slots and bays, and the fourth the system board or riser type.[3] The PC 300PL types 6862 and 6892 and the IntelliStations also begin 68, so the type alone does not identify the series; check the name on the machine's label.

The 486 models have IBM's SelectaBus riser, which can be changed to give either VL-Bus or PCI local bus slots.[2] Wikipedia states that the PC 350 with type 6586 has an Intel-designed system board with an Intel/AMI BIOS.[1]

Power supplies

[edit | edit source]

IBM's maintenance manual gives the supply capacity on each type's specification page: 145 W for types 6265, 6275, 6272, 6282, 6284, 6561, 6562, 6862 and the 6X7X group; 200 W for types 6285, 6560, 6588, 6589, 6591, 6592, 6598, 6892 and the 6X8X group.[3] The PSREF gives 145 W for the PC 330 and PC 340 and 200 W for the PC 350.[2]

On types 6265, 6275, 6285, 6561, 6591, 6562, 6592, 6862 and 6892 the 20-pin main power connector is on the riser card; on the PC 360-S150 it is on the system board.[3] IBM's service limits, measured with the supply connected, are +4.75 to +5.25 V on +5 V, +11.4 to +12.6 V on +12 V, −4.5 to −5.5 V on −5 V, −10.8 to −13.2 V on −12 V, and +4.75 to +5.25 V on Power Good. The +3.3 V output is checked at 3.3 to 3.46 V on the system board and 3.17 to 3.46 V at the riser. If the voltages are wrong and the power cord is good, IBM's instruction is to replace the supply.[3]

Battery and BIOS

[edit | edit source]

The CMOS backup battery is a 3 V lithium cell, IBM FRU 33F8354, on the types in IBM's maintenance manual.[3] IBM's checkout procedure has the latest BIOS installed before any part is replaced, because an old BIOS can cause false errors and unnecessary system board replacement.[3]

Known problems

[edit | edit source]
  • On the PC 300PL 6862, the AGP slot sits away from the riser and needs an NLX-format video card with its connector mounted high. A review of a 6862 found that the label under the cover gives switch settings for Pentium III processors up to 550 MHz; with the latest BIOS the reviewer ran an 800 MHz Pentium III, and a 1.3 GHz Tualatin on a PowerLeap adapter.[4]
  • The same reviewer found that a PC 300XL (6588) asked for Setup to be run after any configuration change, even unplugging the mouse.[5] The 6588's DIMM sockets take EDO memory; a commenter on that review notes that SDRAM DIMMs fit but do not work.[5]
  • One owner on the Badcaps forum found three CHHSI 560 µF 25 V capacitors (WG(M) series, date code 9846) on a PC 300PL with intermittent faults. Another member advised replacing every CHHSI capacitor; replacing those three did not cure that machine.[6] See IBM PC Series 300 Capacitor Replacement Guide.
  • IBM's G51 and G51t CRT monitors (6541-02N, -02E, -02S, -Q0N, -Q0E, -Q0S), sold from June 1997 to December 1998, were recalled for repair in 2003 because the circuit board can overheat and smoke.[7]
