FA-PDT-11/150 on eBay

Jerome Fine replies: When Megan Gentry mentioned that the PDT-11/150 is able to do a LLF (Low Level Format) on the 8" floppy media, I asked about the possibility of a hard disk drive. Does the PDT-11/150 use the DX.SYS device driver to run the RX01 floppy media? I know there is a device driver called PD.SYS, but I am not sure what it supports. Also, from what I understand, the PDT-11/150 can run RT-11, but not RT11XM, only RT11SJ and RT11FB. And the maximum memory is probably 64 KBytes with the IOPAGE taking either 8 KBytes (or 4 KBytes?).
