This is a tricky one. Probably your best bet is to contact Mentec and see what they have to say about it. The downside being they'll probably want to move you to V5.7 and that would cost you for both an upgrade license and media kit. The upside being V5.7 is Y2K compliant (though if you're still running V5.4B you probably don't care about that). Mentec can be found at http://www.mentec.com Did you loose your Hard Drive, and are trying to get the system back up and running, or is that still working? If the system is still operational your best bet is likely to be making your own set of floppies. If you don't have any blank RX50's, but have a PC with a 1.2MB floppy drive, you can use PUTR.COM and make your own RX50's. Zane
