Hello All.
Just a quick note to let anyone interested know about recent work
on the freebee emulator:
1. There is now a simple man page that provides an overview of
the 3B1 and freebee.
2. You can scale the display independently in the X and Y directions by
scale factors from 0 to 45. This is useful on large / high resolution displays.
3. The 3B1 serial port is now emulated! This allows remote login from
the 3B1 to the host or vice versa, as well as file transfer.
4. All of the filenames and several other features that used to be
hard-coded are now configurable via a configuration file in TOML
format. For example, the RGB values for the display color.
Configuration of more things is on the way (I hope).
Check it out!
Arnold

So cool! Now that you have serial working, can you add C-Kermit to your >drive image? Then my life will be complete ;-)

Binaries are kicking around.
Version 5A(189) is here:
http://www.unixpc.org/3b1/caltech/kermit.gz
In David's VCF disk image, he includes a newer version 5A(190) at: >/usr/local/bin/kermit
There are also even newer version 8 binaries here, but the executables
are pretty big (650k-700k):
https://www.kermitproject.org/ckbinaries.html#att
I think it's supposed to be self-contained executable without additional >auxiliary files.

I put the version 8 binary onto my disk image as /usr/local/bin/c-kermit.
I also updated Brian Kernighan's awk while I was at it.
Enjoy,
Arnold

Thanks for this! I was able to transfer a 20M tar file of customizations from my 3B1 into my full-lots-sw.img freebee and still have enough room to untar it and copy the stuff I want. I'm not sure how much other than /usr/peter that will be, now thatyou've pre-loaded so much software. If I come up with anything that looks generally useful, I'll itemize it and share the disk image back.

Great use of the Pi 400! I wonder why the 3b1 looks to be running faster than FreeBee. I’d expect the Pi 400 to be able to run full speed. I’ll have to play around on my machine and compare to your hardware footage.
Jesse
Peter, I realized tonight that the FreeBee Makefile default is to build the debug, not the release build. Probably worth trying rebuilding with BUILD_TYPE set to release in the Makefile. I'm about to try out on my Raspberry Pi 4 - man, can't believehow fast these are!
I tested with 'release' instead of 'debug' but didn't notice a change on RPi 4. If I encounter anything else to help performance on RPi, I'll let you know.
Running with release is a lot faster on the Pi 400, see: >https://www.youtube.com/watch?v=L9nB1WibEKM

file but you'll get artifacts. You can also use x_scale=2.0, y_scale=3.0 (no artifacts) but the window will be pretty huge (1440x1044).Running with release is a lot faster on the Pi 400, see: https://www.youtube.com/watch?v=L9nB1WibEKMGood deal. Glad to hear it. I like the side-by-side comparison so you can see how wide the framebuffer is (720x348) versus the 4:3 CRT. If you want to scale the Freebee window to 4:3, you can use x_scale=1.0, y_scale=1.55 in the .freebee.toml config
Cool! It's amazing (to me) that you have a still-working 3B1!
Take good care of it. Glad to hear that compiling for release
makes a difference.

I read that the QEMU emulator may support m68k, found this reference:
https://github.com/vivier/qemu-m68k
I'm not sure that others support the chipset (ie: Vmware, Parallels) --
tho I'm sure this has already been explored.
I'm just responding in context.
A long time ago, I had someone perform a PAL upgrade to my 3b1 and it
broke it. I was so mad, but that was the end. Now, I wished I had
kept it around to further repair it.
I don't really see UNIX PC or 3b1 for sale anymore...
