I got amazed by the possibilities of bit cell exact disk capture as presented by the <a href=\"http:\/\/eab.abime.net\/showthread.php?t=40959\">Cyclone20<\/a> and <a href=\"http:\/\/www.kryoflux.com\/\">KryoFlux<\/a>&#8230; and so I wanted to build my own disk capture unit.<\/p>\n<p>I recently bought a <a href=\"http:\/\/www.beagleboard.org\">BeagleBoard<\/a> clone board called <a href=\"http:\/\/www.igep-platform.com\/index.php?option=com_content&amp;view=article&amp;id=46&amp;Itemid=55\">IGEPv2<\/a> and soon the idea emerged to build a stand-alone disk copy unit based on this board. In the end I&#8217;d like to have a box with a floppy drive and a beagle with sd card slot. I can insert a disk to capture and then press a single button to create a bit cell exact and bit rot resistent disk image version on the SD card&#8230;<\/p>\n<p>I started experimenting with the AT91SAM7x CPU used as a sampler device in the Cylcone20 and KryoFlux projects. Since no public firmware exists I wrote my own version from scratch. I don&#8217;t use USB for data transfer but an SPI channel between SAM7x and the Beagle. The beagleboard runs Poky\/Angstrom Linux and therefore the host capture tool is written in C using spidev in user space. All processing tools working on the sampled bit cells are written as Python scripts.<\/p>\n<p>Now everything works really well, i.e. I can capture a disk trackwise and store the samples reliably. Furthermore the conversion tools now can extract a bit stream, decode AmigaDOS blocks and derive an ADF Disk Image in the end. Its by far not a finished project but its in a state you can already work and experiment with&#8230;<\/p>\n<p>If you got interested then head over to my <a title=\"DiskFreezerX\" href=\"http:\/\/lallafa.de\/blog\/diskfreezerx\/\">DiskFreezerX project page<\/a><\/p>\n","protected":false},"excerpt":{"rendered":"<p>Hi all, its now quite a while that I released something&#8230; But I wasn&#8217;t lazy in that time.
