Mike Padgett Archive

Introduction

In October 2025 Mike Padgett posted in the "SS50 & SS30 Computer Bus Chat" Facebook group page that he was the original owner of, and still had in his possession after 40+ years, a very complete Gimix system that he was putting up for sale. A few years ago it had still booted up.

Refer to the Mike Padgett Gimix system page for more information on the hardware of this Gimix system, including many pictures.

Mike also had 19 floppy disks containing software from Gimix, Microware, and Smoke Signal Broadcasting (SSB). One of the disks contains OS-9 GMX III (support ROM version), which nobody had been able to find -- until now! He had also kept a complete set of original documentation.

A few days later Mike sold this system to another member of the Facebook group, "Howard Michaels", a former employee of Gimix. This was so much better than if Mike had sold the system to an anonymous collector who then disappeared without making any of the documentation or software public. Thank you, Mike!

Since the new owner didn't take possession of the system for several weeks, Mike scanned much of the documentation while he still had it. The plan was that in the coming months the new owner would then scan the remaining documentation, capture the contents of all the floppy disks, hopefully capture the contents of the hard drive, dump the EPROMs, etc. All this valuable information would be posted on multiple web sites to ensure it remained available for many years to come. I am hosting one copy of these archives on my web site, with links on this page.

You are allowed to make copies of these files, and of the information on this web page. If you post those copies publicly, please credit Mike Padgett and me (David C. Wiens) appropriately.

Mike has asked us to refer to this system as the Mike Padgett Gimix system, to help him and future conservators keep track of this machine and its origin. Similarly, he has asked us to refer to the documentation scans, data, and code from this system as the Mike Padgett Archive.
