TePhOS 9t9

You will find below (coming soon) our first official beta release of TePhOS and along with it some useful PDF manuals in regard to the Grommy2 hardware and over the coming weeks more useful manuals, disk images, and cartridge dumps being added, to be able to make full proper usage of our TePhOS release on your Texas Instruments TI-99/4(a) Home Computer systems and compatible emulators.
 

PLEASE NOTE: – As per the terms listed on our license page, you are required after using our TePhOS firmware on your system for more than 30 days, out of the kindest of your human heart, donate a small one-time payment of $20 USD to the developer, for each installation of the firmware. — Funds raised will go towards updates and support our future releases and more upcoming Texas Instruments software and hardware, and help support the overall improving the health and well-being of our main developer GaryOPA. — Thanks! 🙂
