I have fiddled a lot with my SL-C3000 over the years and ended up reformatting and restoring the hard drive, using the image from trisoft's site. It is now running as far as I can tell but there is one odd thing: when I launch the info application and go to the third tab, it says that the ROM Version is "--.-- JP", which is rather peculiar.
Has anyone seen this? Is this a problem with the image file from trisoft? I am rather keen on getting everything back to where they were when I bought the thing so obviously I am slightly disturbed by this anomaly.
