I'd be interested in 8.
make me an offer.
I'd do $175 just for playing around with the board.
I think you should just keep on mining with them until they are no longer profitable. You won't get all that much for them now. Also the fact that they lack the typical boatload of I/O options found on full development board means they have limited use as a dev board, so once again their market value beyond bitcoin mining (or perhaps alt coin mining?) is limited. Just my 2 cents. In the end it's up to you what you do with them. Good luck with your auction!
I've got 40 more listed on bitmit.net... I've got great feedback on them and will do escrow. Buy 8 or more and get a nice, high quality USBhub, powered.

make me an offer.
How's 150+shipping sound?
I have also listed some on bitmit.net at the below address for a few bucks more (due to fees) but included Escrow.

I've got quite a few...199USD in via PayPal shipped within continental USA only. (The used chips are worth approx 75 each, so my price is firm). If you have a home serving running....plug a few of these in to make a few bucks on the side. They use very little power.
make me an offer.
anyone selling these??
how many you need? i have 3 of them.
Just curious: how much would you let one go for?

Dear FPGA Mining customers,
Unfortunately, demand for FPGA miners has been too low in recent months to justify continuing to produce new X6500s. For the foreseeable future, FPGA Mining will be suspending operations. It's sad to step away from such an exciting and interesting project, but the time has come.
Thank you all for your interest and support! We'll still be involved in the Bitcoin world and hopefully find a new project to participate in soon!

It is a pleasure to use your miner. It has already more than paid for itself!
anyone selling these??
Any chance you guys will get into the ASIC market?
I think I have SHA1 firmware laying around in one state or another. Been too busy to tinker with that sort of stuff.
Fizz and the gang,
Good doing business with you over the past year...
Do you have any plans to explore alternative firmware for existing boards?
Care to entertain bounties for MD5, SHA1, DES, etc cracking bitstreams?

@Fizzisist:
Thank you for doing all that you have done for Bitcoin thus far and I look forward to your future projects!

Thanks for the x6500 guys, it's a great little FPGA board.
Hi !
I'm using the sock heat sinks.
The non working FPGA is getting warm, yes, the working one is really hot like it used to be, but the non functioning one is just getting hand warm.
It's not loose though..
It still has the error "More than 99 JTAG devices on chain... " wtf ?!
I had no reply from fizzisist for few days.. messaged him privately..

Hi ocminer,
Sorry for the delay in getting back to you. It's not clear what's going on with your FPGA to cause this. "More than 99 devices..." sounds like the TDO line is stuck high, so the computer is reading in 11111111... when detecting the number of devices in the JTAG chain. The first thing you need to check is whether power is present. If you have access to a voltage meter, you can probe the sides of the large electrolytic capacitors to check that the supply voltages for the FPGAs are being produced. It sounds like FPGA0 is working fine, so you should probe C58. This should read 1.2V (VCCINT for FPGA1). After checking that, we can think about other possibilities.

@ocminer:
I would give him a bit more time to get back to you. But in the meanwhile, I would identify the problematic FPGA and remove the stock heat sink. Check the chip to see if there are any bubble / deformities and if it is clear of them, clean the chip off with a small amount of rubbing alcohol. You can at this point replace the thermal tape on the heat sink (just make sure you clean the base of the heat sink thoroughly).
If the chip has bubbles / is warped / cracked, then you are likely out of luck. Best of luck to you and I hope its just some bad thermal tape.
