One thing that I don't think has been mentioned is that the guest OS being run under SIMH might not take kindly to data changing on these new devices that are being proposed. I would expect the guest OS doesn't expect things to "magically happen", because it (quite rightly) believes it is the o

Just to add some info to the discussion. This sounds like a nice idea,however it will be very difficult to implement on some of the oldermachines that SimH supports. For example the B5500 does not have the concept of a mountable pack.Drives could be attached, but they were a permanent attachment. F

I second kermit as a general purpose solution. It also supports non ascii character sets which for some older systems is important. Failing that paper tape as a txt file works. Sent from my iPhone > On 20 Apr 2016, at 18:00, Sampsa Laine wrote: > > >> On 20 Apr 2016, at 19:58, Johnny Billqu

I think I wasn't clear on what I meant. Simh would have an FTP server built in. In your simh control file, you'd attach a disk (or tape, or drum) and add an option that would make that block device available to the FTP server as a certain virtual directory name. A user id and password would als

Actually, why not just create simple file system for the FTP server, and then export an interface and create a read/write tool for each OS. That way you only need to implement one FTP server and a tool to access files on it. This sort of exists for the Z80 emulation - there are read / write ut

A common theme on this list is how to get files copied between the host and the emulated machines. I have a crazy idea for a simh feature to help in that regard: Add an FTP server to simh that would write to a "universal" file system on a simh block device file (disk, tape, drum) that the guest
