VirtualT, Tandy TRS-80 Model 100 emulator for DevTerm A06 & A04

I’ve pushed the changes I’m using to build VirtualT for DevTerm A06.

I’ll accept pull-requests and I’ve added a discussion area. This is not my code. I just hacked it to build on DevTerm A06.

todo: Fix fullscreen mode.

Added a quick hack to the makefile to allow building on A04. Maybe.

A04 users. please test and let me know if it works.

(Or send me an A04, of course.)

Hi Steven.

Really appreciate your work on this. I just tried running it on my A04 and it failed.

Many errors or warnings during the install.

Here’s my log of the make attempt:

Ah! I got fullscreen working by accident after a chaos filled hacking session. Now to figure out how. :wink:

P.S. Pushed a bezel cleanup fix to the repo. Also, you can upgrade without fear of overwriting your configs with these builds. Just a ‘git pull’ is all you need to do in the existing VirtualT-DevTerm directory.

Thanks to the 10 old-timers that appreciate this work. :wink:

This is definitely some amazing work. I love it. The only issue I have at the moment is some fullscreen issues in i3, but I absolutely love this :slight_smile:

Works perfectly on A06. Is there any way to force it to fullscreen for that pure retro look? I tried F11, no go. Love this regardless. Thanks for porting it over for us.

Unfortunately, it looks like devterm’s xfce isn’t honoring the fltk gui library’s method of calling fullscreen. So fullscreen may never work on the devterm. I have created a ‘devterm’ size that gets pretty close (auto-hide the menubar for best effect.) Honestly, the code is spaghetti because it was trying to be compatible across windows, osx, and linux. Cleaning it up just for devterm helps, but hacking it has been difficult.

That said, I have pushed a fix that allows it to build on the manjaro devterm spins and nearly any other linux system. I’ll cleanup the readme for manjaro building when I get a chance.

Here’s a screenshot of VirtualT-DevTerm compiled and running on Ubuntu on Windows 11 and using the new native Windows X11 subsystem…

@Steven_Boger could you share a commit with your fullscreen attempt?
I’ll see if it helps by using lowlevel x11 calls.

Like this?

Awesome! I was hoping for some community involvement! My DevTerm is currently in pieces. Let me get it back together and a OS installed and I’ll get some testing in so I can get it accepted.

PR merged! Thanks Yatao Li! I’ll need to clean up the readme and try to get fullscreen to be a proper checkbox option, but we’re FULLSCREEN now! (I’ll push an official release once the other stuff is complete.)

Now we’re talking! I demo’d VirtualT in my latest YouTube channel video, said I was hoping for fullscreen, then checked back on this post forgetting I had asked about it earlier! And planning on experimenting with the Manjaro distro in the next weekend or two.
