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??

[Lightbulb]

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?

[uberfoo]

Yes, we will have them for sale at this year's DEF CON! And, since we had extra time we've hidden secrets in it and there will be a CTF of sorts. The prize with be the retail cost of the badge, so essentially you get your badge for free if you win. We are real excited about it.
More details to come as we get closer to DEF CON.

[Lightbulb]

Have you figured out when this will be available? Will Hacker Warehouse be selling these?

[uberfoo]

The Z80 Retro Badge will be for sale this year at DEF CON 31! We plan to sell them via Hacker Warehouse at the original list price of $130.
There is a CTF associated with the badge. Winner of the CTF will receive $130.

[uberfoo]

Good news everybody! We are now taking pre-orders for the Z80 Retro Badge. You can find them at this link: https://shop.uberfoo.net/products/z80-retro-badge
Pick up will be at #Defcon We will be posting additional batches after testing. We are excited to see you play the #ctf!! #defcon31 #badgelife
(Note: we will not be selling via Hacker Warehouse, sorry for any confusion).

[Lightbulb]

Where and when is the pickup at defcon31 ? I have not heard any follow up, unless anyone else has?

[qumqats]

what is the I/O on this? I don't see anything that looks like video out, or a serial port, so how to you interact with it?
(BTW awesome looking, I already have one ordered and am looking forward to playing around with CPM)
Thanks!
