Because every single Amiga Scart cable is designed for it + it lets you use external scandoublers and commodore CRT monitors. With the rest go nuts... The only other feature I'd be interested in besides the keyboard would be an RTC.

Yeah the 23 pin is staying.

Guys, you have forgotten that Brian opened gerber files only, not design itself, so person who will add an rtc circuit will need to redraw riser from scratch (or use Beprepared's brd from his github repository)...
Adding rtc is easy doable if it's done in smd, actually have planned to take it from Rafals A604 or PeteAU's ram expansions, only few component's are needed..

And yes, 23p connectors isn't problem still have 50x of them lying around

Ian Stedman has an open riser design that was never fully realised, on his Github.

https://github.com/istedman/cd32_breakout

Indeed he credits it as being from a TerribleFire design? Seems like there's a lot of cross pollination in the CD32 riser world!

USB keyboard/Mouse support sounds great, wireless even better!
USB Joypad support would be very welcome,
I dont have a multi button controller for mine yet and the prices seem to be getting silly. Niche markets and availability eh?
Is Mouser the only place the risers are available from? Ive done a few orders with them in the past, fast and reliable they are.

The 5650092-1 edge connectors are also available from Digikey, but the price is essentially the same.

There is a basic riser that i created and Ian Advanced. I would start from scratch TBH... Doing PCB designs doesnt take me long.

@8BitDreams what kind of adapter are you selling with TF328 and TF330?

And this is new. They used to be available at Mouser only. Good to know there's an alternative now. However, these connectors are the prime example of what happens when we start buying an item. The price more than doubled compared to when we started bulding the 328, which is why I had to raise the final price...

Last time I ordered 105 of these it came to over $800 and that's no pocket change.

I have finally got around to releasing the KICAD files for the FB-32G Module on GitHub. I finished it quite some time ago, but life really got in the way.

https://github.com/Bprepared/FB-32-CD32 ... /readme.md

If anyone wants the specs for module dimensions they can be found on EAB here:

http://eab.abime.net/showthread.php?t=88826

I had also started the schematics to add an RTC and Clockport in the next module iteration, but time is still pretty slim for me, so I'm happy for anyone to pick this up and run with it.

105? My question is, what are you going to do with that extra connector left over at the end?

Perhaps if you guys all agree not to order any more for a month or two the algorithm will bring the price back down
