Over 45 Years of Mainframe Solutions

Connect/MP — formerly ZIP/390 MP

Version 7 Is Available Now

ZIP/390 MP is now Connect/MP, and Version 7 is available now.

Upgrade strongly recommended. Version 7 is the current release, and all new development now occurs there — and the gap grows with each release. Your existing jobs run exactly as they do today, the same JCL, with no price increase. Version 7 does require a new license key, and that key is what switches on the new capabilities only Version 7 provides — a browser workspace, REST API and MCP access, and uniform TLS among them.

Email support@data21.com to request your Version 7 key.
