The Z80 Retro Badge

[uberfoo]

So, my badge this year was inspired by the ongoing chip shortage. Rather than try and find modern chips, I decided to go old school. I present the Z80 Retro Badge by Uberfoo Heavy Industries.
This is a fully function 8bit microcomputer model after so of the first generation of personal microcomputers.
The plan is to have CP/M 2.2 running on this so it will be able to run original Z80 software including some old text adventure games like the Zork series.
4x addressable RGB LEDs are included for requisite blinkyness. An expansion port opens up possibilities for adding additional hardware in the future.
The badge will be available from Hacker Warehouse during DEF CON for $130.

I love it!

Need.. Just need..

Garrett needs to take my money, then. This is one of the most comfortable CPUs ever created. Those powerful block moves and that swap-all-the-registers opcode were the best.

They ran out . Will you make more??

Yes I was one of the first folks in line & they never even had it for sale, because they had not received it on Thursday. It was listed on the board too

I asked about this at the Hackerboxes booth and they said it needs to be ordered online. I can't find it on the Hackerboxes site. :( Anyone know where to look? TIA

My sincerest apologies to everyone. In addition to a couple of manufacturing defects we had to rework which put us in a huge time crunch, we discovered a design flaw in our power supply that prevented almost all the badges from booting up correctly. Because these problems, we decide not to sell our badge yet. We absolutely do not want to sell an inferior product.
We plan to immediately work on a redesign the power supply and we will keep everybody posted here and all of the other channels we've advertised through of the progress and we will try and make online sales to those who want one. In addition we plan to sell the badge at next year's DEF CON and we may have another exciting new badge from our team too.
Again, we're very very sorry about this and hope to make it up to everybody in the very near future.

Yes, please, I'm super interested in this badge. Let us know when you are going to make it available. Thanks!

Good news everybody!
After a successful prototype run, our new power board design was proved out. Recently we sent it over to manufacturing and a first batch of power boards arrived last week and those were tested and they work! Then, yesterday, the final shipment of power boards arrived. We mislaid our 20 pins headers somehow, some we need some replacements before final assembly.
On the compute board, we have restarted assembly of the remaining unassembled boards. We discovered a low yield when testing some of the parts we sourced. Particularly, the ATF750 chip we use for our custom ZBridge probably has the lowest yield of any part, and it's not a cheap or easy to find part to find. We've found a source and hopefully yields will be better giving us more assembled boards. SIO/2s, which we are also short on, are also difficult to find at wholesale prices and are usually more expensive than the CPU. We've managed to source those now too, albeit at a much higher price than we would prefer. We expect to have all the parts needed for our target numbers by next month. Giving us plenty of time to finish then before DEF CON.
On the software front, since we've had extra time to work on it we've been able to add cool features and other surprises. We've nearly finalized the firmware and we have some cool stuff we're working on that runs under CP/M. Expect games and maybe a CTF-like experience.
We are still trying to finalize plans as to how we are going to sell and deliver the badges. We may offer an option to buy online for delivery. We will probably try and sell through Hacker Warehouse again. We just have not finalized any of those plans yet, but I will try and keep you informed as we start to put plans together.
Finally, let me present the first assembled and fully operational Z80 Retro Badge:

I want this Z80 badge… I waited in line last year at the Hacker Warehouse line during DEFCON30, just for this

[internetking]

will make more for defcon 31?
