keith
Well, I’ve switched servers at my webhost. I’ve updated WordPress and Gallery. No major changes, but both of these updates fix security vunerabilities. I’ve been wrapped around this for a...
SlackFest 2007
Ok, I’ll admit it. I’ve been slacking like the best of them. I’m not horribly unsatisified with my progress, especially this year. The first four months of this year I achieved the following: * Whole...
java client works
Well I’m producing correct .ADF’s with the new java client. The terminal mode is also finished and working. I have some various odds and ends to wrap up with it, namely allowing the user to save his...
java client preview
I’ve put up a preview of the java client in action. It’s a 2 minute video with narration. You’ll need a DivX codec installed in order to view it. I probably could have messed with compressing this...
java software progress
This morning I added MFM decoding, header and data checksumming and checking to the java client. I was somewhat worried about doing the MFM decoding, but it was all worry for nothing. Once you wrap your head around how...
java software
I’ve been working on the Java software the last couple days. Trying to read from RXTX is producing only 3968 bytes per read. It looks like my USB -> serial converter uses a “transfer size” of 4096...
java and portability
While I have some experience with Java, I’ve never tried to run my stuff cross-platform. Never a real need. While most of the Java stuff has yet to be written, I took some basic serial code and GUI stuff, and...
Marco Veneri
I had the great pleasure of trading emails with Marco Veneri today. He is the original author of the Amiga Floppy Reader(AFR), of which I refer to very frequently, and have based most of my work to date on. I have...
thinking about cross-platform support
To make this accessible to everyone, I’d really like to add support for more than just Windows. I thought that Java would be my ticket to freedom here, but that is turning sour real fast. From what I’m able...
added byte-sync to my transfer routine
Well, after much thought, pondering, and discussion with David, I finally implemented a working byte-sync routine to my SX software. I don’t have it fully working with the PC side software yet, because this...
new face of the amiga floppy project
You’d think that with the lack of posts lately that I haven’t been doing anything. BUT, in fact, I’ve been quite busy. I now have the entire floppy project on one single circuit board, the SX28...
reworking my uart
Well I rewrote my recv and send uart, and with the help of my logic analyzer, I’ve tuned them up pretty good. I’m getting some transfer errors, somehow, and I think its related to buffer size. I read a disk...
On speed optimization
The theoretical limit, assuming 300rpm drives, is 200ms per track. Or 400ms per cylinder, or 32 seconds per disk. Most attempts read slightly more than one track. I read 16,384 bytes, or 262ms worth. Right now, if I...
Good news good news. First perfect .adf
Good news indeed! I’ve managed to create a fully functioning .ADF from a floppy. I matched the output from my hardware/software combination with a “transdisk” output, and it matches exactly. I used...
working cause of bit errors
I think I’ve stumbled on something. I don’t think I’m capturing enough data. 13,824 has been my magic number forever. It was larger than the 13,800 that Marco used in afr.c. But I’m beginning...
