What is new in Beta 5?
This is the first beta to run on real hardware! I am currently running Punix on my TI-92+. It's still highly incomplete, but the hardware drivers have been proven to work correctly on the Real Thing. As a real calculator has limited power (batteries), this release now supports power-off with the key combinations 2nd-ON or Diamond-ON.
This beta also includes a short clip from The Blue Danube Waltz (to demonstrate the audio capabilities) as well as preliminary grayscale support. The console font has been anti-aliased to take advantage of this new grayscale support.
For those who are interested in running this release on their own calculator, here are some quick installation instructions. First make sure that you have a GraphLink cable (or a homemade variant) and TiLP installed on your computer. TI-Connect might work as an alternative to TiLP, but I've never used it so I can't say whether it works.
- Start TiLP and navigate to the directory that contains the .9xu/.89u file.
- Pull out one of the calculator's batteries.
- Reinsert the battery while holding the APPS key until the bootloader screen appears (It will say "Press I to install product code...").
- Press "I". The bootloader should say "Waiting to receive..."
- In TiLP, drag the appropriate .xxu file from the computer side to the calculator side. If you have a TI-92+, drag the .9xu file. If you have a TI-89, drag the .89u file. (Sorry, only these calculators are supported currently.)
- Wait for the transfer to complete. This should take a couple minutes.
- Punix will automatically boot after installation.
Please be aware that Punix does not have an "Auto Power Down" (APD) feature yet, so you will have to power down the calculator with 2nd-ON when it is not in use.
