I'm writing my own SCP decoding app, initially for extracting files from TI-99 formatted DSDD disks. I believe I am able to parse the SCP files in their entirety. Now I need to figure out what I'm looking at with the flux data.
I currently contain the flux values in a byte array. One sample track of a disk has alternate low and high decimal values. If I understand the SCP format, I'm looking at 16-bit pair values in HIGH-BYTE/LOW-BYTE sequence. Does each 16-bit value represent a flux intensity in a range from 0 to 65535?
I converted the first 300 bytes to HEX values and got the following:
002E0108010901090109010901090109010901080109010901090109010901090109010901090109010901090109010901090107010A010A01090108010B0107010A0109010B01050086008200880108010A0106008700850083008500870106010B01080109010A01090108010A0107010C0107010A0107010A0109010A010801090108010A01090108010A0109010801090108010A0109
Any guess as to what I'm looking at?
