HP 3000 Series 33

The 3000 Series 33 was a step down from the Series III. The Series 33 was the first HP 3000 that didn't come in a standard 19-ich rack. The Series 33 came in an integrated desk configuration (a configuration that HP would use for another 7 years). Like the Series III, the 3000 Series 33 ran the MPE III operating system. It came standard with 256 KB of memory, expandable to 1 MB (rather than the 2 MB supported by the Series III).
