Quarterdeck Manifest 1.x

Manifest is an easy to use diagnostic program that provides incredibly detailed information about DOS resource usage, loaded programs, IO devices, and memory usage including EMS, XMS, and UMB memory. It was available as a standalone program and bundled with QEMM and Deskview. Tools like this were essential for resolving compatibility problems between poorly behaved DOS programs and highly customized environments, especially in task switched or multitasking environments.

Notably, Mainfest can measure the speed of different sections of RAM or ROM. Commonly, speed could differ when memory was located on different devices such as ISA RAM cards. Sometimes performance could be improved by moving resident programs or ROM in to faster parts of memory.
