If you, like I do, have multiple monitors on you working machine, instead of giving any 98 machine more than one screen, clone your working drive. Then, all you have to do is rename the clone machines when it is running using the Network tab in Control Panel, and on your main machine share your file drive, full access, then you have full access for each machine to one file source drive. And, there is no hassle in this version of Windows, everything goes as it should.
I have my main machine on an SSD, and the other two are running from their original Virtual Drive directory, which I have on a 12 gb drive on the Mediasonnic.
I went ahead and installed Yahmaha 100 synth also, so I have both the 70 and 100 synths.
You can download Autocad lessons on Youtube and put them on their own virtual box to run in 98 itself also, if you like.
