The cost of z/TPF architecture can vary significantly depending on several factors, including:

1. Hardware:

• Number of CPUs: More CPUs will increase the processing power and cost.
• Main storage capacity: Larger main storage capacity will be more expensive.
• Number of IOPs: More IOPs will improve I/O performance but also increase the cost.
• Channel bandwidth: Higher bandwidth channels will be more expensive.

2. Software:

• z/TPF operating system license: The cost of the z/TPF operating system license varies depending on the version and features required.
• z/TPF application development tools: Additional software development tools may be needed, which will incur additional costs.

3. Services:

• IBM maintenance and support: IBM offers maintenance and support services for z/TPF systems, which can be a significant ongoing cost.
• Installation and configuration services: Third-party vendors may offer installation and configuration services for z/TPF systems, adding to the total cost.

4. Infrastructure:

• Physical space: z/TPF systems require dedicated physical space with controlled temperature and humidity, which can be a cost factor.
• Power and cooling: z/TPF systems consume significant amounts of power and require dedicated cooling systems, contributing to the operational costs.

Additional factors:

• Customization and integration: Any customization or integration with other systems can add additional costs.
• Training and staffing: Training staff to operate and maintain z/TPF systems can be a significant cost.

Here are some general cost estimates for z/TPF systems:

• Entry-level systems: Starting around $100,000.
• Mid-range systems: $500,000 to $1 million.
• Enterprise-level systems: $1 million and above.

It’s important to consult with IBM or a qualified z/TPF reseller to obtain a specific cost estimate for your specific needs.
