Vintage 1984 McGraw-Hill MIX Information Exchange Welcome Kit with Apple II Simulation Disk & User Guide

Step back into the dawn of classroom telecommunications with this exceptionally rare, complete 1984 welcome package for the **McGraw-Hill Information Exchange (MIX)**. Long before the modern internet took shape, MIX was a pioneering online networking service designed to connect schools, teachers, and classrooms via modems. Because this subscription service was marketed directly to educational institutions rather than the general public, surviving pieces are incredibly scarce—most were thrown away decades ago during school technology upgrades.

This remarkably well-preserved archive is a true time capsule of early digital culture and an incredible find for Apple II completionists, digital archivists, or vintage computing enthusiasts.

### What is Included in this Complete Archive:

* **Original MIX 5.25" Simulation Diskette:** Labelled "APPLE II SIDE 1 Startup," copyrighted 1984 by McGraw-Hill, Inc. This diskette allowed educators to boot up their Apple II systems and interface with or simulate the online network.

* **Official MIX User Guide:** A beautifully preserved booklet featuring iconic 1980s tech illustrations on the cover, detailing how to navigate the early online exchange.

* **Personalized Subscriber Welcome Letter:** A formal letter from McGraw-Hill's Eden Prairie, Minnesota headquarters addressed to the subscriber, complete with the original, unredacted 1980s "MIX User name" and "Password" sticker intact.

* **MIX Licensing Agreement:** The original legal terms and conditions document outlining the usage of the network.

* **Original Mailing Envelope:** The vintage, typed shipping envelope from McGraw-Hill Information Systems Company in Eden Prairie, MN, providing excellent provenance for the entire set.

### Condition Report

This set is in excellent, vintage condition. The paper documents, user guide, and licensing agreement show only minor edge wear and natural age toning, with no major tears or heavy staining. The 5.25" floppy diskette appears visually clean and well-kept inside its protective white paper sleeve. Please note that the diskette is sold **as-is/untested** for functionality, as we do not have a vintage Apple II setup to read or test the data.
