W. Moeller Utilities DK* and PK* are patches to DKdriver and PKdriver which allow use of JAZ drives on older VMS versions (e.g. VS2000). NDFP0543 is a unique set of code which runs on a VMS machine and a PC which allows files or peripherals on the PC to act as though they were locally attached to the VMS machine. This includes disks and tape, though due to MSDOS peculiarities, CDs are not able to be made virtually present in the same way. (Whether the free PCDOS on this tape has the same problems is unknown.)
