The Modern Terminal Built for IBM Z and IBM i.
AnikaZEE is a high-performance native desktop emulator built with Rust and Slint. It delivers seamless dual z/OS and IBM i connectivity, full PCOMM EHLLAPI drop-in parity, and an audited, zero-trust local AI assistant.
The Mainframe Terminal Re-Engineered.
AnikaZEE running on Windows and macOS: authentic 21-tool PCOMM action bar, dual TN3270 & TN5250 engines, operator-guarded AI assistant, and built-in host LSP code editing.

Engineered for Banking & Mission-Critical Infrastructure.
System/77 builds software that honors 40 years of mainframe reliability while delivering state-of-the-art developer ergonomics.
Dual TN3270 & TN5250 Enterprise Core
RFC 1576/2355 (TN3270/E for IBM z/OS) & RFC 1205/2877/4777 (TN5250/E for IBM i & AS/400). Native support for IBM-3278/79 (Models 2–5) and IBM-3179-2/IBM-3477-FC (24x80 to 27x132 colour).
- z/OS (SDSF, TSO, ISPF, CICS) & IBM i (WRKACTJOB, CL, RPG, OS/400) sessions side-by-side
- 5250 Write Structured Field (WDSF), subfile controls, Field Exit & ATTN keys
- RFC 4777 password substitution (IBMRSEED / IBMWSBPM) auto-signon
- Tabs, split-screen (side-by-side, 2x2 up to 3x3), IND$FILE & PDF print exporter
Agentic Mainframe AI Assistant
A dedicated side drawer that explains mainframe screens, diagnoses abends, and safely drives host sessions under explicit human operator oversight.
- Three execution modes: Ask (read-only), Edit (approves key-by-key), Auto
- Works with Anthropic, OpenAI, Azure, Gemini, Ollama & LM Studio
- Message Doctor underlines z/OS error codes with immediate fix actions
- Operator skills for SDSF job output, ISPF 3.4 datasets, and CEMT
Personal Data Shield & Policy Control
Built specifically for banking, government, and financial compliance. Ensures private user data never reaches external AI models or logs.
- Automatic regex masking for SSNs, credit card numbers, IBANs, e-mails
- Custom corporate regex pattern definitions
- Windows Registry (HKLM) & macOS MDM profile administrative lockouts
- Audit log trace and daily assistant token cap enforcement
Mainframe LSP Language Service
Built-in code editor for members and sequential datasets fetched directly from z/OS hosts, with full conflict checking before writing back changes.
- Built-in LSP client for host-connected language servers (COBOL, HLASM, JCL, PL/I, RPG)
- Semantic syntax highlighting, symbol navigation, and real-time diagnostic squiggles
- Member conflict detection before host dataset overwrites
- Local scratchpad and host file synchronization
EHLLAPI & MCP Automation Engine
Preserve your existing enterprise screen-scraping investments while adding next-generation Model Context Protocol automation for AI orchestration.
- Drop-in 64-bit hllapi.dll supporting standard IBM PCOMM functions
- Built-in Model Context Protocol (MCP) server for modern AI agent integrations
- Automated screen scraping and keystroke playback with operator speed controls
- Export session recordings to automated testing scripts
Enterprise PKI & Data Sovereignty
Smart card-enabled, banking-certified TLS encryption, secret security, and robust corporate proxy support.
- TLS 1.3 with client certificate authentication (CAC / PIV / Smart Card)
- Enterprise proxy traversal (SOCKS5, HTTP Connect) with Kerberos/SPNEGO
- Local-only execution with zero telemetry data egress
- FIPS 140-2 validated cryptographic modules
Built for Financial Institutions & Strict Governance.
System/77 designs AnikaZEE with zero-compromise security defaults. Bank security teams retain complete control over AI capabilities through central OS policy deployment.
Automatic regex masking replaces credit card numbers, SSNs, IBANs, and custom corporate patterns with placeholders before reaching any model.
Managed via Windows Registry (HKLM\Software\Policies) or macOS MDM profiles (.mobileconfig).
Connect to internal enterprise LLM gateways, Azure OpenAI private endpoints, or local Ollama / LM Studio runtimes.
Full wire traces, session logs, and key approval history stored locally for forensic auditing and regulatory reporting.
