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:
“Do not require a description of the countries towards which you sail. The description does not describe them to you, and to- morrow you arrive there, and know them by inhabiting them.”
—Ralph Waldo Emerson (1803–1882)
“The type of fig leaf which each culture employs to cover its social taboos offers a twofold description of its morality. It reveals that certain unacknowledged behavior exists and it suggests the form that such behavior takes.”
—Freda Adler (b. 1934)
“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)
