RX33 (or RX50) image of XXDP?

Jerome Fine replies: That is a very nice configuration. The ESDI drives will be much faster, as will the SCSI drives. They can also provide backup for each other if you produce any files that you want to save. To format the RD54 with the RQDX3 controller, you require the ZRQC?? (IIRC) format program. Probably somewhere on bitsavers or classiccmp under XXDP. If you can't find ZRQC??, someone else may know where an XXDP floppy image which contains ZRQC?? is located. It will probably be an RX50 image (which an RX33 drive can handle - best to keep it in WRITE PROTECT mode). I probably have it somewhere, so if you can't find it, bug me! If you need help running it, this is the place to ask! You can download the following CD image for all of the RT-11 binary releases up to V05.03 of RT-11. After you unzip the file, it has 4 RT-11 partitions. You can boot "RT11DV10.ISO" using the SIMH emulator or the E11 emulator as an MSCP device at unit 0. I STRONGLY recommend that you use RT11DV10.ISO as a READ ONLY device under both SIMH and E11! Under E11, the commands are: MOUNT DU0: RT11DV10.ISO/RONLY BOOT DU0: http://www.classiccmp.org/PDP-11/RT-11/dists/RT11DV10.ISO.zip If you are able to burn a CD-R, INCLUDING BLOCKS 0-63 (which are sectors 0-15 on a CD), you can also boot from a SCSI CD drive with unit 0 under E11 and using your PDP-11. I don't think that SIMH allows a CD to be used as a raw device. If you have RT-11 questions, please ask!
