Thanks to a VERY generous loan from my dad, I just placed an order for 50 fully-assembled boards (as well as 10 completely-untested Twiggy breakouts), and I'm planning on bringing them to VCF Southwest to sell. I'm in talks with two well-known distributers in the vintage computing scene, and any boards that don't sell by the end of the weekend at VCF will go to them to be listed on their web stores. Not sure how quickly 50 boards will sell out, but I'm planning on doing more orders in the future once they're gone. I wanted to get more than 50 to start, but JLCPCB only had 54 FPGAs in stock, so the max I could do without having any leftover bare boards was 50.

And of course, if you don't want to buy one from me or them, you can always order some of your own straight from JLC once I put everything on GitHub!

They will sell out quickly.

Hopefully not too quickly!

JLC just finished manufacturing the boards, so they should be shipped out pretty soon. Hopefully they'll be here by VCF; it's going to be really close!

I just added a neat feature that very few people will probably ever have a use for, but it comes in handy for me sometimes with LOS experimentation, as well as with Xenix's hard drive size limits. If you connect one of the pins on the GPIO header to 3.3V, then the FPGA will intercept any reads to address FCC030 and always return 88 instead of A8, making software think that it's running on a 2/10 instead of a 2/5. Pretty neat, right?

Sorry, I completely forgot to respond to you! It's looking like about $300. I really wanted it to be cheaper, but the prices of chips have gone up quite significantly since my last order. Take the FPGA for instance. When I placed my first order back in November, it was $20 apiece, but now it's like $50. And many of the other chips have increased by similar proportions too. It sucks!

Will there be any available for shipment to folks who are not planning to attend VCF?

AlexTheCat123

Yep, I'm working with MacEffects and Joe's Computer Museum, and whatever doesn't sell at VCF will be split 50/50 between them for sale on their sites! Once those sell out, I'm planning on doing another batch too.
