[excuse this second copy of my reply; worried that my first went into the Great Bit Bucket In The Sky] Charles said: You will have very good success using Will Kranz' TU58 emulation on a PC as an intermediate store: http://www.fpns.net/willy/pdp11/tu58-emu.htm He has a MSDOS flavor and a Linux flavor. I've used the MSDOS flavor as a way to image RL01s and RL02s for archival on other media (CDROM). Be sure to read his documentation about patching the DD.SYS driver (renaming it to DW.SYS) to allow the emulated TU58 to have the same capacity as your RL02 cartridge. Don't worry, it's not difficult and when I first did this myself I had sub-zero DEC / PDP-11 / RT-11 experience. While fairly slow (it is RS-232 serial, after all), the extra benefit your will enjoy using this method, is that you automatically will have a backup of the installation that Henk made for you and that you no doubt suffered some small expense to get. If you have any more questions about using Will's TU58 emulator, feel free to contact me directly. - Jared
