TurboBoard w/ Blue Lightning CPU
TurboBoard 60/65/80 (DX2-66/0MB P/N 05003417)
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).
TurboBoard w/ Blue Lightning CPU (IBM FRU 71G2610, ASSY 0500340)
- 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 4MB of RAM, expandable to 128MB
- An integrated video controller with up to 1024 x 768 pixels with 256 colors,
non-interlaced; or 1280 x 1024 pixels with 16 colors, interlaced. The controller
is supported by 1MB of dedicated video memory.
- One serial port and one parallel port
- Diskette drive interface that supports 1.44MB or 2.88MB diskette drives or tape
- Integrated hard disk interface that supports a maximum of two ATA hard disk
- 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
