Sub-Etha Software

In 1990, Sub-Etha Software was formed in Lufkin, Texas. You can read all about it, if you are curious. Since then, much has changed. It’s hard to believe that was almost 25 years ago!

Although Sub-Etha hasn’t been active in years, for the past few months, I have been posting on my Apple site,, about my exploits with the Arduino platform. I haven’t done this much recreational programming since my days using the Radio Shack Color Computer. This has made me decide to dust off my old software company, Sub-Etha Software, and set up this website. Although I have had the domain for many years, it was just a subsection of one of my personal sites… until tonight.

I have now migrated all my programming-related posts from the Appleause site over to this one. I think they will fit in better here, and it finally gave me an excuse to do something with this domain.

So here it is – the all-new Sub-Etha Software website. Here you will find historical information about the original Sub-Etha, which started back in 1990 to offer products for the Radio Shack Color Computer and Microware OS-9 operating system. There is even a page which will eventually document the items we made for the Interactive Media Systems MM/1 computer, which ran OS-9/68000 (“OSK”). At some point, I may even make a page covering some of the items we sold after I took a job with Microware and had to shut down Sub-Etha. (Hint: Sub-Etha SoftWEAR didn’t sell software…)

Around 2001, I learned a bit of Perl programing and created a few simple scripts which I made available free under the Sub-Etha Software name, so Perl gets a page here, too. And lastly, some of my recent development efforts on the Arduino and related devices like the Teensy 2.0. I may even through in some BASIC Stamp talk at some point if I ever dig out my old hardware.

But since Sub-Etha started with the CoCo, it remains with the CoCo. There will be discussions about new CoCo related projects, and a listing of some CoCo websites I think all CoCoists should check out.

Take a look around! More stuff will be coming…

      Hey Carl – great to hear from you. You just missed the CoCoFEST! Brian Shubring (Glenside MIDI guy) had your Defeater and a copy of Photon. It would have been nice to have you there to re-show us how to use that. Drop me an e-mail sometime!
