Hi all — I'm the original developer of the ADB I/O, a data acquisition module I designed years ago and distributed through BEEHIVE Technologies for classic Macs. I have 5 units listed on eBay if anyone here is interested, and I'm happy to answer any technical questions about it directly.​


This is a rare opportunity to own a piece of Macintosh computing history. Up for sale is an original Beehive Technologies ADB I/O unit, preserved in its original, unopened packaging for over 25 years. In pristine, "day one" condition, including the ADB I/O interface, original documentation, and any bundled software/cables as originally packaged.​

The cardboard is crisp and shows minimal shelf wear consistent with long-term storage. Colors are vibrant with no significant sun-fading.​


Seemed like a community that might appreciate it more than a random eBay scroller would. Link in comments / DM me for the listing.​
