PDP-11 Freeware CD's under emulators

Zane wrote: The best way to do this is with John Wilson's full E11, where you can directly mount the high (RT-11 disk structure) partitions of the CD-ROM. Of course, this requires the commercial version of E11 for large disk MSCP support, and also requires a regular (non-hobbyist) RT-11 license to run (as the hobbyist RT-11 license is only good on the Supnik emulator.) I think it also requires a SCSI CD-ROM (though I could be wrong and it'll work fine with an IDE CD-ROM.) The next best way to do this is free, and doesn't require commercial anything, just the Supnik emulator running on your system and a copy of RT-11 in compliance with the hobbyist license. If you look in the RT-11 freeware CD at the ISO9660 partition, you'll see that each and every piece of software on the CD is represented as a logical .DSK file. In particular, in the /dsk directory, you'll find 185 logical disks of freeware, split up between the SIGtapes, the DECUS 11-xxx entries, and the "other" stuff. These can be mounted as any sort of volume you like under the Supnik emulator, as long as the emulated device is large enough to hold the contents of the .DSK (i.e. you can use an emulated RL02 to hold any virtual .DSK up to 20480 block.) Then you're home free, and have "direct" access under the emulator to all the contents. -- Tim Shoppa Email: shoppa(a)trailing-edge.com Trailing Edge Technology WWW: http://www.trailing-edge.com/ 7328 Bradley Blvd Voice: 301-767-5917 Bethesda, MD, USA 20817 Fax: 301-767-5927
