Visualizing amiga track data with matlab
So looking at a lot of raw data is pretty tough, but matlab handles it with ease. So the above image shows a sample amiga track from a brand new disk, just recently formatted, within the amiga. It is basically as...

Pretty 🙂
I like the colors.
I know someone that does *everything* from one spool of blue wire, and it drives me nuts.
Thanks.
I don’t know if this means anything, but the first thing my wife said about it was also “Wow. Pretty colors.” 🙂
Soldering those wires on the pins of the IDC connector was a real pain in the ass. I basically created a small C, hooked the pin, pushed it to the base, and soldered the wire to the pin to the pad as best I could manage. I think my wire gauge is a bit too big. I think this is 22ga? Maybe 24? In any event, its really too big. And considering there’s no serious power/current coming through these, it could be much smaller.

Hello,
Interesting project.
2 questions though.
1) Doesn’t this solution require a software component to make the hardware work
2) From the 2 pics and schematic, I’m confused on how the Parallax USB2Ser Dev tool is connected
Hi Lee,
Thanks.
1> Most definitely. This is the reason and purpose for the java client. It has a big role.

It sends the commands to the microcontroller to step the head, read the track, transfer the track to the PC, decodes the MFM, writes the ADF file to the HD, etc.
2> USB2SER has two connections
a> to the SX28 microcontroller via TTL TX, RX, and flow-control pin
b> to the PC via USB
This help?
