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...
Success!@#
I hestitate to jump to conclusions, but I think I just passed a crucial first step in getting this to work!@#!# After adjusting some timing on my new code on the SX, I’ve found my first 0x4489 0x4489 pattern. This...
SX software progress
Welp, since I fine tuned the PC to very reasonable numbers, I figure a small overhaul of the SX code is in order too. I had somewhat of an epiphany working the on the SX, which I haven’t *really* looked at in...
Speed of the reading on the PC
Ok, well I’m now satisfied that the PC is fast enough to do its portion of this job, using the standard WinIo dll. I managed to redo a portion of the code so it’s faster, and the total time on the PC is 6...
more followup winIO vs inpoup32
I did a little informal write test. A small tight loop that simply raises pin 1 and then lowers it again. Both in as little code as possible, as clean as possible. WINIO: Total time to raise and lower again, 2.5us...
followup on speed of inpout32
Welp, did some testing last night, and no, it doesn’t look like inpout32 is really going to be any faster. Damn shame because it was relatively easy to setup and use. Quick reply from the authors(thank you) who...
inpout32.dll vs WinIo
From a previous post, I mentioned WinIo as a nice way of accessing the parallel port from win2k. However, it was slow. The authors said, “I should be using MapPhystoLin() anyways”, whenever I asked about...
Latest Cisco Aironet 352 PCMCIA Drivers
For convenience, please find the current (as of May 2005) Cisco Aironet 352 PCMCIA drivers available below:
Win-Client-802.11a-b-Ins-Wizard-v15.exe
Parallel port access in win 2k
Accessing the parallel port directly under Windows 2000, XP, etc in a standard user app is not natively available, but there are a couple different solutions available. The free one I use is called WinIo, and it is...
Finals week at pitt.edu
Welp, this is finals week, so don’t expect anything new to show up until after April 28th, 2005. But, this doesn’t mean I’ve forgotten about this project! I am very much interested in moving this...
too many variables
I think that’s really the problem I’ve been facing with this floppy project. Trials and tribulations indeed. Or at least trial and error, with stress on the error part. There are probably less than half-a...
Site updates
Hi, I made some changes at my provider. I now have access to mysql which really opens up the world of various add on packages. I didn’t initially need or look for this support, but I have it now. I also have a lot...
