Welp, I’m having trouble tweaking my existing SX code. If I modify the timing of the current code, I’m getting all garbage output — even adjusting small amounts to one side or the other, produces much...

more success reading valid data!
I created a disk with a textfile called AMIGA on it which contained thousands of “AMIGAAMIGAAMIGA” throughout the entire file. The idea here is that no matter which part I happen to read/decode, I can tell...
more SX to PC tests
Although I think I’ve long had this working good, I did some more tests just to verify. Latest numbers: Each cycle is about 15.8us, 2us per bit, 8 bits, this sounds fine. This does confirm, however, what I...
SX code
Ok so I’m using SX/B, which is BASIC for the SX. Even if you’ve never touched SX/B, it reads very easily, anyone who knows the PIC or other mcu should understand….. Here’s the logic behind the...
floppy.c’s mfm decoder
A couple days ago, whenever I got ahold of floppy.c, I wrote a quickie code stub that utilizes floppySectorMfmDecode from floppy.c of fellow (). Note you must use the mirrors to actually download anything…. This...
test results of my output file
What I wanted to know was if the output file that I collected via my setup was actually correct. I was confident that since I was getting 4489’s consistently, that I have to be at least part way...
an output file from my project
DiskMonTools says it's reading 16200 bytes. My project is reading a filesize of 15892 consistently.
Here's the link to the sampled file.
will put up sample files
I’m going to put up a sample file or two, but I wanted to get the smallest complete group of bytes that I can…. ie like one full sector, etc. So far, I’m just basically streaming bytes, via disk copy...
