The MEGA65 has dual SD card slots as well as the floppy drive.
The first 400 sold out within 8 or 10 hours. Less than 900 in the second larger batch remain available at last check.
A small ARM cannot emulate the MEGA65's 40MHz CPU or 81MHz pixel-clock VIC-IV video controller, unfortunately.

You're quite correct that this is an oversight of ours. I thought Trenz had already put the schematics etc on their website as they are manufacturing the PCBs and selling the units for us (we are currently between the 100 devkits having gone out, and being ready for pre-order for final machines, so unfortunately you can't just yet order one, but later this year we expect to open pre-orders). We will solve this one way or another.

Yes, it would be quite possible to make a core for that. You are welcome to pitch in and help write one :)

While the final machines are not yet purchasable, you can buy an off-the-shelf Artix7/Nexys4DDR FPGA development board and run the core on that. This has been supported for several years. Also with 100 devkit machines sold and in people's hands, its definitely not vapour ware.
... also, if anyone is interested in helping us with maintaining the website, that would be very welcome.
One of the other things we have been doing with Serval in the Mesh Extender devices is making it possible to connect external radios, including HF radios from Codan and Barrett, for really long range inter-cluster communications.
Yes, we know we need to fix the website and app store. This is the pain of depending on grants to get work done :/ Getting the app back up on Play Store is our current priority.
Howdy, as the founder of the Serval Mesh adhoc networking protocols and hardware, what I would look for in a new radio is: 1. True packet radio mode, that doesn't hide the radioness of the link etc, but lets the programmer use it's strengths. 2. UART link, ideally using 3DR/RFD900 compatible connector (then we can include it directly in our existing systems, and so can others). 3. Field-flashable, but with robust protections on the boot loader, as it is not uncommon for a radio to be on the boot serial interface, on hardware that has only one serial port. 4. Support 434, 868 and 905-935MHz ISM bands. 5. Use advanced interference tolerant wave-forms, like Chirped Spread Spectrum or even something better. 6. Fully open chipset/firmware design, so that it can be truted. Anyway, poke me at [email protected] if you would like to talk further about it. Paul.
