Vintage 1989 official IBM technical documentation binder containing both the MVS/ESA JCL User’s Guide (GC28-1830-1) and MVS/ESA JCL Reference (GC28-1829-1) for MVS/System Product JES2 Version 3 and JES3 Version 3. Housed in an original red IBM heavy-duty 3-ring easel binder, this complete documentation set covers IBM System/370 mainframe systems.

Vintage pre-owned condition with visible signs of age and shelf wear. Pages exhibit mild overall age toning/yellowing along the outer margins, but text remains clean, crisp, and fully legible with no torn pages observed. The original red IBM 3-ring binder shows minor surface scuffing and light storage wear around the edges. Please see photos for full cosmetic condition.

Please refer to the photos for exact measurements.

​An essential piece of computing history and a rare find for serious vintage tech collectors or legacy IBM mainframe preservationists.
