First page has a title written by hand with a Marker which reads: "SYS/38 Hands-on Lab" (Please leave on Console) * Appears this was the main copy used to learn the basics of the program. Each Printed page is numbered, if the numbering system is correct there are 135 pages total, all still attached using the continuous tractor feeding paper of the era. All pages have an alternating color scheme with a green bar alternating with a white bar. The edge of the pages is marked Printed in the USA. Each page has numbered lines which correspond to the lines where the computer is likely to print text on from 1 to 57.
Top page has some dark foxing on the edges but the yellowing fades substantially by the next page and it is not visible by the page that follows that one.
The System/38 is a discontinued minicomputer and midrange computer manufactured and sold by IBM. The system was announced in 1978 and delivered in 1980. The System/38 had 48-bit addressing. The predecessors to the System/38 include the System/3 (1969), System/32 (1975), and System/34 (1977). In 1983 the System/36 was released as a low-end business computer for users who found the System/38 too expensive for their needs. The System/38 was succeeded by the AS/400 midrange computer family in 1988, which originally used a processor architecture similar to the System/38, before adopting PowerPC-based processors in 1995.
