great tips!.. thanks! the photoshop plug-in is great!
Does it open them perfectly converted? i.e. it looks identical to the way it appeared on the Plus?
If so, a standard file format that has been supported intact from its inception in 1984! Amazing!
Another way to transfer is to Print them using LaserWriter driver v7.0 which came with System 6.0.8. It is compatible all the way back to System 2.0/Finder 4.1. Simply open in MacPaint and print to PostScript file. This works for any application, not just MacPaint, for which files many have no modern conversion options. The resulting postscript file readily opens under Preview or Adobe Acrobat. NOTE: it must be v7.0 as earlier versions do not produce compatible PS files.
In addition to working on the original Mac, it will also work under Mini vMac.
