Paying a monthly subscription just to emulate a 1970s green-screen terminal is absurd. So I built my own. Meet X3270: A free, native macOS TN3270/TN3270E emulator.

Built from scratch in pure C++ and Cocoa. No Java. No X11. No Electron bloat. It has implicit TLS 1.2+ via OpenSSL and full ISPF Query Reply support.

Free and open-source forever. Read the architecture breakdown on my blog: https://www.dockerr.blog/blog/modern-free-TN3270-terminal-client-for-mac-free

Getting #AI to work reliably in production requires not just new tools, but integration with the legacy tools that still run systems of record at many large companies.

Updates over the last two months to workload and #mainframe automation tools from #Broadcom, #BMC and #IBM will begin connecting #agenticAI to systems at the heart of the most critical enterprise workflows.

Check out my roundup of these updates here: https://www.techtarget.com/searchitoperations/news/366642753/Bridging-the-gap-Legacy-tools-gain-enterprise-AI-support

Are you paying for mainframe software nobody uses?

Many enterprises carry unused or obsolete software that still consumes budget and MSU capacity.

With Z Asset Optimizer, you gain visibility to identify unused assets, reduce license costs, and plan modernization more effectively.

Start with clarity before you modernize.
