Re: 11/83 operating system load update -2
To test the false "Write-protect" error, try: Put a BLANK floppy in the drive, and ask Windoze to FORMAT it. For simplicity, choose the "360K" or "720K" format. See what if any errors that generates. If no errors (or certain specific other ones), then we can assume that the problem is not with the drive. If it gives a "write protect" error, even with Windoze FORMAT, then the hardware seems to be seeing a hardware write protect. Besides the obvious possibility of a defective write protect switch, or a cable mismatch, one of the MANY unlikely other possibilities, . . . I have seen and used floppy drives that were jumpered to reverse the write-protect sense. Try it again WITH a write protect tab on the disk. That would confirm THAT particular issue. Also, put a disk into the drive, and try a simple READ, such as looking at DIRectory. Assume that you will get errors, but WHICH ONES? I can understand your refusal to use Linux. But, are you willing to reboot to MS-DOS? If not, at least try FORMAT in a DOS CMD window. Disk I/O error messages in DOS are more meaningful than the over-simplified messages that Windoze gives. -- Grumpy Ol' Fred ci...@xenosoft.com On Wed, 23 Feb 2022, Rod Smallwood via cctalk wrote: Hi Well I have had a huge response to my request.

As long as you’re running 9x, PUTR should work as intended. I highly suspect the issue lies with either the floppy controller, or the floppy drive itself. It would be worth inspecting the floppy drive to make sure lint or other detritus isn’t blocking the write protect mechanism. I had similar issues with the RX50 in my 11/23 Josh Rice.

Maybe for Win95, but Win98 and later uses its own 32-bit port drivers (I'm not certain about 95 OSR2). If running 98 or 95, just do a "shutdown to MS-DOS prompt", rather than opening a DOS Window and you'll be fine. --Chuck

I don't know PUTR, but my experience with DOS int13 code in RSTSFLX (built with DJGPP) is that it worked fine in a DOS window on Win95. And that makes sense, because Win95 is basically just a bit of UI veneer over DOS. Win NT is an entirely different thing, of course, and I would not expect DOS low level I/O to work in Win NT command windows since those really are not DOS. paul

Re: 11/83 operating system load update -2
I think you're unnecessarily limiting your options by refusing to use Linux, which as we've pointed out is something you can do on your existing PC without overwriting the OS that is on it now. As for SIMH, I am quite convinced that it IS a perfectly good answer. But sure, if you have all the floppies you need to do an actual install via floppy media, that's fine too. It does limit you somewhat; it means you have to use an OS for which RX50 was a supported kit type. For example, RSTS/E doesn't come that way, so if you want that, the SIMH route is your only option. And it would not be hard to do so long as you can find a PC interface for that SCSI drive. paul > On Feb 22, 2022, at 9:29 PM, Rod Smallwood via cctalk > wrote: > > Hi > >Well I have had a huge response to my request. > > I am unsure as to if I have defined the problem properly. > > So a few bullet points. > > 1.

Hi Rod, The "*.dsk" format is just a file extension. What utility created the RX50 disk images?
