These are all from a high end Beta deck. Assuming all perif.

Finally something I deal with a lot!
Previously for me
A) midgrade
B) peripheral (probably)
C) up to the dock
B/c I normal pack such boards in a small box inside my shipment. Enough to make someone actually look at them. Otherwise they may be simply tossed aside for being brown.
I also tend to send board photos after the quote when I email my quote number and tracking so they are aware of what’s in there.

B/c are borderline and ultimately decided at the dock. Same issue on the main board.
I’ve had these go both midgrade and peripheral.

Looks like a late BII or early BIII unit?

If it works to any degree and you know, or know someone who knows, how to do some basic board work you could easily turn the main board into a tri-region board. This one looks to have the tracings for PAL timings.
You need only one capacitor, two resistors, a crystal oscillator, two MOS controllers, and an nec 7 series cpu. All dirt cheap. Oh, and a bunch of raw nickel spool to make the contact jumps.
The only place you’ need outside help is adding the code to the co primary controller, the nec 3 series on B. It’s not erasable but there’s usually enough room on it to add the assembly as a patch. The code can be grabbed from AV Forum, Doom 9 etc.

With the effort a working multi-format Beta board with stereo (II/III) can run $25-$50 on eBay. The parts complete cost under $5. A small computer shop will probably charge you $10 or so to dump the code from a usb to the controller.

I was impressed by this beast because of how all of the options were laid out on the diff boards. I know what these cost when they were new, and to see that all the boards inside are mid grade is funny / ironic / laughable. Was going to sell whole but I saw someone at a ham swap with 6 at 20 each working, I just thought that I needed to let go.

They run $10-$XXX on ebay today
The problem with Betamax/Betachord is that are hundreds of different implementations that are incompatible.
They all play the tapes acceptably but each had its own feature that no one else did.
The early price tags was from the price of ICs at the time. Which was astronomical. 64k in the 70s could be $500 or more depending on factors.

II tends to be the best selling right now, a good mix of advanced technology with stereo sound and buffering via ram. But without the commoditisation of the 80s era III where two identical units could be worlds apart in quality.

Bottom late II with “support for BIII”, lol, uh, nope
