I've visited the factory in Shenzhen last week and they have started to source components for the next run.


So they build it without your physical assistance?

How large run will it be?

Proberbly extra I/O board with it's own CPLD/FPGA and associated circuitry. And use a partly serialized version of the bus. Half the cost of Minimig perhaps?

A 1-bit SPI would give a theoretical 3417 kB/s without overhead. Any real life values?, I hope there's 4-bit routed to the SD slot such that the "parallell SPI" mode can be exploited.

With reservation for errors:

Price: 220 EUR
Chassi: No, except backplate for additional cost
Daughterboard: Only as a thought currently
Delivery: Soon, but other things take time from this project

How about opening a FPGA Arcade Facebook page ? That way everyone can follow any changes in real time, and everyone can commend and share stuff. We can add images and stories.

Or maybe someone would like to open the Group on behalf, so that Mike does not have to spend time on it ?


P-p-please NO,. Facebook tries to infest every aspect of life. I guess it's not even browsable from 68k AmigaOS.
Mixing this project with other activities and with three-letter organizations just brings on tech illiterate people.

A) FPGA Arcade
B) FPGA Replay
C) Minimig
D) Replay Board
...etc ?


I like FPGA Arcade.

daughterboard doesn't even exist as a schematic drawing yet asfaik..

"FCC and CE approval" now that is something that cost and might take time.
Good effort!

Asfaik, send it in or compliance testing, expect failure and then correction, repeat until you fixed all demands. That gives you a paper you can shove the EMC inquisition. Cost approximate 20-30k USD per test.

Maybe time to consider another filesystem than FAT32 ?

UFS perhaps? ;)

Regarding the memory controller on FPGA Replay. Maybe a solution is to have the logic-core to measure and adapt the timing to the memory on-the-fly ..?, or at least som kind of dynamic update.
