Worlds smallest 68k FPGA turbo board

key features:
Artix7 - FPGA (215k Logic Cells)
64MB SD-RAM (32Bit Bus)
16MB FlashROM
Micro-SD-Card Slot
SPI-BUS

Form factor: just about 5mm taller than an original 68k in its socket. :o

The core used is  tg68 Core from the MIST-project @50MHz:  w.i.p..
It is MMU and FPU promised to be implemented; or a licensed Apollocore if feasable. :)

It is supposed to get KickFlash functionality and SD-Card-boot. Current focus is on stability of the core.

This little thing could be a nice drop-in replacement for the CDTV-CPU, for instance.

Also interesting for, ehm, Sega Genesis, Apple Mac Classic....

Yes! And it should be cheaper than the full-fledged Vampire; just an accelerated "CPU" and some Megs of FastRAM (and a SD).
If it reaches 030/33MHz+ terrain it could be a real alternative for the CDTV, as mentioned already. With a different layout even an A600 version is possible.

Edit
The used FPGA seems to cost 100€ á piece.

I think so too, but Matze can split himself only aprox. 8 times, before he has to admit he is no longer capable to sustain all his projects. And this project is OS, so any customer can load whatever he wants into the device.
How any license is invoked is none of his business.

Apollo core is useless for AtariST users, and for hardcore Amigans too, but for those other systems there are signals required that are not yet confirmed to be available yet and by wiring up those connections the range for potential host systems gets bigger, no matter what Apollo core consists of.

If they cover the mini board with some ceramic-gold lookalike, that would be really cool in an A1000. :D
