Description
The IBM 5100 is based on a 16-bit processor module called PALM (Put All Logic in Microcode). The IBM 5100 Maintenance Information Manual also referred to the PALM module as the controller. The PALM could directly address 64 KB of memory. Some configurations of the IBM 5100 had Executable ROS (ROM) and RAM memory totalling more than 64 KB, so a simple bank switching scheme was used. The actual APL and/or BASIC interpreters were stored in a separate Language ROS address space which the PALM treats as a peripheral device. Prices ranged from $11,000 (16k model) to $20,000 (64k).

Famous quotes containing the word description:
“I was here first introduced to Joe.... He was a good-looking Indian, twenty-four years old, apparently of unmixed blood, short and stout, with a broad face and reddish complexion, and eyes, methinks, narrower and more turned up at the outer corners than ours, answering to the description of his race. Besides his underclothing, he wore a red flannel shirt, woolen pants, and a black Kossuth hat, the ordinary dress of the lumberman, and, to a considerable extent, of the Penobscot Indian.”
—Henry David Thoreau (1817–1862)
“God damnit, why must all those journalists be such sticklers for detail? Why, they’d hold you to an accurate description of the first time you ever made love, expecting you to remember the color of the room and the shape of the windows.”
—Lyndon Baines Johnson (1908–1973)
“As they are not seen on their way down the streams, it is thought by fishermen that they never return, but waste away and die, clinging to rocks and stumps of trees for an indefinite period; a tragic feature in the scenery of the river bottoms worthy to be remembered with Shakespeare’s description of the sea-floor.”
—Henry David Thoreau (1817–1862)
