Hi Chris

I'm loving the idea you are developing, I'm just getting back into the retro vibe with my a600 and was wondering when and how much of my money you would want.

Happy to volunteer as a tester if you still need one ;)

Regards
Zak

Thanks for your kind words. The prototype boards seem to be working well for people so far.

The next step is to finalise the hardware layout and order some PCBs for the release candidate board. I will do that very soon. I'll probably end up ordering 40-50 PCBs & hand assemble those. Parts are always more expensive in low quantities so at a guess we'd be in the £20-£30/€22-35 ball park. If I order this week then I might have boards ready in early November. Firmware upgrades to follow as people report problems or suggest features.

Ultimately if they sell then I want to try to buy assembled from China in larger quantity to get the cost down. I'd need to order hundreds in one go which is a big upfront cost (few £k :O) and a bit of a risk. I need to develop an automated program & test for this to be practical too... I have a plan to do this with an STM32 and/or CPLD.

So if you want one cheap then you need to wait for the bulk order. If you want one sooner and support the development then hopefully next month I will have a bunch ready.

Nice product,

Certainly interested in at least 1.
Will the firmware be open source?, later on I would like to add features myself if possible.

Hi Chris

Thanks for the response. Is there a how to use it guide for us to read while we wait in line?

Also putting 2 & 2 together I went to Boobip.com, howcome there's no coming soon section for this emulator on the website?

If it helps the cause I'm happy to put down a deposit for one of the next batch you are making.

Regards

Zak
