Tech question: Stream data from SD card

[upsfeup]

I noticed that this project uses an SD card to stream data to the floppy and I'm damn curious how this was accomplished since the stream has to be done fairly quickly and the SD feeds CRC bytes that have to be jumped.

Any idea, hint, suggestion, clue how this is made? Yesterday night i almost didn't sleep thinking about this.
Maybe Jeff can shed some light on this.

Look at the SRAM chip somewhere on the board

Humm I think that the SRAM was added to give write support. Is the full track read to the SRAM and then fed to the MFM? It might take too long to buffer. in the beginning of each track!

Although one might think that a floppy drive is old technology, nothing compared to today's microcomputers, it still is a good challenge!
