PLM80 V4 docs needed

OK, time again to dust off the old brains out there. I found a ("the") ISIS-II emulator that runs under dos, which comes with a PLM80 compiler. It also comes with link, locate, objhex and other goodies. The PLM80 compiler identifies itself as PLM80 V4. I worked on the development of the ISIS-II stuff at Intel in the very early 80's as well as on the National Semiconductor Starplex system (anyone remember that one?) so I am able to tinker around and remember how most of this works, but version 4 of the PLM80 compiler is getting the better of me. I have the PLM80 Programmer's Manual, but it is for earlier versions of the two-pass version of PLM80, version 4 was a single pass version that used the linker and locator, all of which was the precursor to the PLM86 compiler and tools. I believe this version came out shortly before the 8086 was introduced, everyone went on to the segmented world and never looked back, which may explain why there isn't much out there for it. I am not able to locate any information on this version 4 of PLM80 anywhere, and the use and format is definitiely different from prior versions of PLM80. Anyone out there have any information or pointers for me? I have tried all of the excellent repositories of manuals and emailed Herb, his site indicates that he might have what I need. Anyone have an ISIS-II set of manuals sitting around that can check for me? Specifically, I am in need of: 98-00268B plm 80 programming manual, V4 Thanks. Jeff Erwin By the way, I am running the ISIS-II emulator in a DOS box under windows, itself an emulator. Windows is running under Parallels on my Mac Pro which is running OSx. Is it possible to get further from reality here??
