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

First Alpha of UA is ready.
Write low-level code once with a clean, portable instruction set. Compile to x86-64, ARM, RISC-V, 8051, and more. No compromises.

One assembler to rule them all.

I'm building UA. A language that reads like high-level code but talks directly to the registers. The standalone asm compiler do PE, ELF, or raw binaries without any ext. linkers.

Full manifesto coming soon in the "BOOM".
