Hi all,

DFB1 is a Falcon accelerator which allows you to install up to a 50mhz 030 & 40mhz FPU with user selectable clock speeds via oscillators.

I've built up two of these now, mainly for fun. I planned on keeping one and selling the other, but I just don't have time at the moment. Please be aware that the DFB1 is still a young project and there will be firmware updates on the way, so I highly recommend the buyer be someone who can update his/her own firmwares (Either with a Xilinx cable or with a Raspberry Pi) They are both currently flashed with the latest dfb1r5_2200507.jed of 22nd May 2022.

Link to firmwares on Github: https://github.com/dh219/DFB/tree/main/DFB1/JEDEC

So just to clarify:

* While not a requirement, the ability to flash the firmware yourself for updates is highly desirable. It isn't hard to program a Pi to have this ability: https://linuxjedi.co.uk/2021/11/25/revi ... pberry-pi/
* This does not come with support of any kind, like I said it is an early project. You can contribute and help @Badwolf by providing diagnostics and tests on a variety of different Falcons.
* No FPU or CPU included, you'll need your own.
* I have tested these at 50Mhz, they come with a 50Mhz oscillator installed. If you prefer a 40Mhz or 33Mhz let me know and I can do that.

First come first serve basis when it comes to green or purple PCB. Thank you @sety for the purple PCB and thank you @Badwolf for everything else, good luck with all your projects and I hope these two boards find happy homes.

To show interest post directly on this page declaring interest & then pm me.

Price £120 each

Just for (semi-clueless) people like me, could you post what the
target machines are for these boards?

ST? STe? Both?

Thanks! :)

Falcon.

Thanks, appreciated! :)

I am very interested. I can flash my own Firmware and have a few 030's lying around. I am in California but headed to the UK in a two weeks.

Was the purple one specifically requested? I'm curious to know which colour is more popular. ;)

Yeah purple got first dibs ;D

Just an update, purple board was sold to Surfbud. Green board is still available as of this post.

Hi Steve,
If it is still available, I hereby stake my claim to the green one.
