That's odd, since I did successfully load (and run) the bootstrap for vdm99 over the same serial connection. I just couldn't get any drives recognized after that point. However, I could only get it loaded at 300 baud. Is there a known issue where some RS232 interface cards only work at 300 baud max? That seems to be the limit for a successful transfer for my system for whatever reason.

Actually, the only WAV files I had were the ones from a single cassette tape full of my own programs; all of these have been transferred successfully to the PC and work fine in emulators. All the other software I have is on 5-1/4" floppies I got a while back from a fellow 99-er; it is this batch I was trying to transfer, not because there's anything valuable, just to see if I could do it and preserve the disks before they fail (several already have).

Yeah, I already tried this. From the documentation I could find it all works OK *if* your motherboard can physically handle the reading and writing of single density disks. Mine can't, and I don't think any driver can make that happen. I replaced the drivers as you described and got everything working, but when trying to read TI files off the drive it was corrupted, inserting fake/dummy files and being unable to read the ones that actually kept the correct name. Also, when I ran the 'test' utility it confirmed my motherboard does not work with single density. If you or others think this is still something that can be worked around I'd love to hear details. I'm basing my comments on the manual.txt file found with TI99-PC which explicitly states how certain motherboards are incompatible and includes the testing procedure I mentioned. Specifically: The stock TI Disk Controller handles only Single Density. If you have one of those Controllers on your TI, your PC must be able to handle Single Density too for a successful floppy disk transfer between TI and PC. If your PC doesn't pass this test, then this software is not for you. I tried using the Omniflop drivers on a Windows 2000 PC and a Windows XP PC and neither one worked or passed the aforementioned test.

Thanks for all the tips. Unfortunately I'm only doing the TI to PC direct connection because all the PCs in my house cannot read single density disks, so I can't transfer that way. I tried, believe me, but all my research has verified that none of my motherboards handle the single density format of my 5-1/4" disks. I even copied to a 3.5" disk on the TI but same issue, single density is the blockade. I'm about out of options at this point, I'll play around with TIIImageTool but I think that requires TI software I don't have. Fortunately the only programs I really care about were BASIC programs I wrote when I was 10. I transferred them via a wav file converter (they were on cassette) a long time ago.

Hmm, hadn't heard of that. Unfortunately it doesn't work for me. Not sure if the speed is also a factor there but when I try to load the bootstrap on my TI with "OLD RS232.BA=9600" it just sits there with a "255" at the top of the screen.

I've been also trying to get the file transfer working. After a lot of random changes I finally got the hook file uploaded by reducing the baud rate to 300 (everything else kept giving I/O error 26). So the hook is up and running on the TI but I can't use it in VDM99. Every attempt to scan gives an error (a COM error box, then error #13.2). I've tried pretty much every combination of COM settings but haven't gotten anything to work. Is the problem that the hook is hard-wired to 9600 and that's too fast for my setup? (I ask since 300 was the highest speed at which I could get the hook to transfer successfully.) I've also tried enabling pausing as mentioned earlier in this thread ... to no avail. I'm running Windows 7 Pro 64-bit. I'm using an actual serial port on my PC. And running the 'no-DB' version of VDM99. Since the hook uploaded successfully it seems like the rest should be do-able, I just don't know how. Not a huge deal, but I thought it would be cool to get my remaining 5-1/4" TI disks transferred to my PC for archival purposes.
