I actually don't know if you can get them through Marvel Digital (I should check - I have a subscription). I bought them on CD back when you could get the 1963-2005 back issues of Marvel's main titles on CD-rom. (And seanchai did some kind of DRM magic with them on her Mac so they'd display properly - for some reason the DRM visibly degraded the image quality on her computer - so I can lend you copies if you need them)
