Installation (Compaq Tru64 UNIX)

You can then display the values set for particular parts of a given subsystem, such as "vm" or "proc", as shown:

#sysconfig -qsubsystem_name

In this command, the value of subsystem_name is "vm" or "proc".

The /etc/sysconfigtab configuration file is read during bootup, and sets the values appropriately.

When using CAD/CAM/CAE or similar three-dimensional graphics applications on Tru64 UNIX, one step that frequently helps improve performance is to add the following line to the end of the /etc/sysconfigtab file:

vm: ubc-borrowpercent = 50

More advanced tuning of your Tru64 UNIX system depends on the type of user activity and data files. For example, if you perform occasional assembly modeling operations with numerous view and edit operations on individual components, adding the following lines to the end of the /etc/sysconfigtab file can also improve performance:

vm:

vm-maxvas = 1610612736

proc:

per-proc-data-size = 268435456 max-per-proc-data-size = 1610612736 per-proc-stack-size = 4194304 max-per-proc-stack-size = 48000000 max-per-proc-address-space = 1610612736

This technique is a suggested first level of tuning to try for average workloads. To achieve the best possible performance on your system, however, you should consult the Tru64 UNIX tuning documentation, experiment with the different tuning techniques proposed, and monitor the results while your application is running.

The 486 architecture enabled users to run more complex applications, enhancing productivity and making it suitable for tasks ranging from word processing to graphics editing.

In terms of memory, the Compaq 300 supported up to 16MB of RAM, which was substantial for its time, allowing seamless multitasking of programs. The system typically included a 120MB IDE hard drive, which facilitated ample storage for documents and software, a critical aspect for users who needed to manage large volumes of data.

The Compaq 300 featured an integrated graphics card based on the popular VGA standard, enabling clear display quality for applications and gaming. Notably, its 14-inch CRT monitor that accompanied the system offered crisp visuals and an optimal viewing experience for users.

Another characteristic of the Compaq 300 was its expandability. The desktop came equipped with several expansion slots, allowing users to easily add components such as sound cards, network cards, or additional storage drives. This feature provided users with the flexibility to upgrade their systems as technology evolved, ensuring longevity in a rapidly changing landscape.

The Compaq 300 also showcased advanced connectivity options for its time. It included multiple serial and parallel ports, providing versatile connectivity with peripherals like printers, scanners, and modems. This adaptability was crucial, especially as businesses began to integrate more technology into their operations.

Durability and reliability were hallmarks of Compaq's design philosophy, and the Compaq 300 was no exception. Its solid construction and dependable components appealed to users who required a trustworthy system for daily tasks.

Overall, the Compaq 300 epitomized the intersection of performance, expandability, and reliability in desktop computing. Its innovative features and thoughtful design paved the way for future developments in the personal computer industry, making it a noteworthy entry in the history of computing technology.
