The IBM AP-101 computers originally had about 424 kilobytes of
magnetic core memory each. The CPU could process about 400,000
instructions per second. They had no hard disk drive, and load
software from magnetic tape cartridges.

In 1990, the original computers were replaced with an upgraded model
AP-101S, which had about 2.5 times the memory capacity (about 1
megabyte) and three times the processor speed (about 1.2 million
instructions per second). The memory was changed from magnetic core to
semiconductor with battery backup.
