J9 CPU bus clock select - up: 33 MHz, down: 25 MHz (the "up" position is closer to the CPU socket/top of the unit; thx Lionel)

J11 Clear CMOS Jumper - CMOS configuration is cleared by switching the jumper from one position to the other. The jumper remains in its new position until the next time you decide to clear CMOS.

U71 Instead of multiple discrete oscillators this planar uses a PLL clock generator (IMI SC422BXB) to synthesize all required system clocks from a single 14.318 MHz source (Y1). The only exception is the 22.1184 MHz UART clock that is generated by a dedicated oscillator (U16).

TurboProcessor w/ Blue Lightning CPU "MODEL 60/80 UPGRADE BOARD", "ASSY 0500340"

IBM FRU 71G2610 [P]

Notable differences:

  • soldered-in Blue Lightning CPU (U79)
  • slightly modified layout with one additional oscillator (below slots Z1 & Z2)
  • U86 & U87 populated (?)
  • U85 populated (PAL)
  • regulator Q1 populated (CPU core voltage?)
  • possibly different system firmware (POST/BIOS)
  • possibly different programming of some PALs

The rest of the board appears to be identical with the one shown above. UMMR has this variant.


  • 486DX/33 or 486DX2/66 processors (standard options at time of order); support for 487SX processor
  • Standard 4 MB of RAM, expandable to 128 MB
  • An integrated video controller with up to 1024x768 pixels with 256 colors, non-interlaced; or 1280x1024 pixels with 16 colors, interlaced. The controller is supported by 1 MB of dedicated video memory.
  • One serial port and one parallel port
  • Diskette drive interface that supports 1.44 or 2.88 MB diskette drives or tape backup unit
  • Integrated hard disk interface that supports a maximum of two ATA hard disk drives
  • PS/2-compatible keyboard and pointing device ports
  • Clock/calendar with integrated battery (10 years)
  • Seven full-length 32-bit Micro Channel expansion slots, including one with extended video and one 16-bit full-length Micro Channel expansion slot
  • Secondary Cache Module
