Hi, A few of you have probably heard about my little project - the portable floppy disc raw-reader/writer. Through a bit of spare-time coding I've got all the basic elements of the reading side of the interface done. That is to say, according to the simulator, my hardware design can detect MFM sync markers, index pulses and track index sequences on hard-sectored floppies. Unfortunately I'm not going to have time to do the PCB layouts and such for another few weeks at the least, which leads me to my next problem... Rather than halt all development due to lack of time, I'd like to take a look at some of the software side of things. What I need are some raw data dumps i.e. if you're using a Catweasel, the data in the CW's RAM after the track read command completed. The 'testhist' utility from Tim Mann's CW2DMK pack can do this, with the command: testhist port drive track side clock [file] The documentation for testhist explains how to use it - port is the I/O port for ISA Catweasels or card ID number (starting at 0) for PCI Catweasels. Drive is the drive number (starting at 0), track and side are equally obvious, clock is the clock rate (0 for SD/DD, 1 for HD). The 'file' parameter is the name of the output file that What I'm after are the raw files (and testhist output if possible) for: - FM encoding, IBM format (PC or similar) - MFM encoding, uPD765 (PC format), 3.5" DD - MFM encoding, uPD765 (PC format), 3.5" HD - MFM encoding, Amiga format, 3.5" What I'm wanting to do is try out a neat little read-compensation algorithm I found that seems to make it easier to decode discs where the FM/MFM timing thresholds are a little ambiguous (the histogram shows a lot of bleed/smear along the bottom). An image of the whole disc would be useful, else a few random tracks would be just as good (and probably easier to FTP/email). Are there any kind souls out there with a Catweasel card and CW2DMK (or a similar tool) that can provide this data? Thanks, -- Phil. | (\_/) This is Bunny.
