In SunSpots Digest v9n106, I asked about an RT-11 assembler/emulator to run on a Sun. Thanks to all who responded. I received responses about two software packages and two offers of commercial assistance: SOFTWARE: From: wbc@cabot.dartmouth.edu (Wayne B. Cripps) |I have something called the CHIP/HOCA system which is sort of what you |want, a pdp11 simulator and c compiler and support. The io is a bit |different though, and in porting it from the vax to the suns, I may have |bit reversed all the opcodes ( It doesn't make any differene to me - I |just need something that students can write and run code on) | |You can ftp pub/sunchip/sunchip.tar.Z from killington.dartmouth.edu. Feel |free to tell anyone! Let me know if it is useful or if the opcodes come |out bit flipped. From: dan@breeze.bellcore.com (Daniel Strick) |I just happen to have an RT-11 emulator that I used to sell in a previous |life. (Don't laugh. I actually made a little money on the RSX version.) |It just happens that I dusted it off recently to use it for benchmarking |sun-4s. The problems are: | |1. I can't provide the RT-11 assembler. This a DEC product and I could | get my posterior severely bruised for giving out copies. (I am not even | certain that I have one. I do have an old RT-11 ZORK binary that runs | faster on a SPARCstation then it ever did on a PDP-11/40.) | |2. I am reluctant to let the RT-11 emulator go for free (and I get the | impression that you are operating on a real tight budget). We might be | able to work something out anyway. This would be an "as is" sale for a | relatively trivial amount that covers my time and effort. There would be | a software license agreement (a contract) to be signed. I think you would | have to indemnify me. (For example, DEC could theoretically sue me for | helping you violate DEC's rights to the RT-11 assembler even if you got it | somewhere else (because I helped you to use it).) | |Dan Strick, aka dan@bellcore.com or bellcore!dan, (201)829-4624 | |P.S. I am not sure, but I think I remember that my PDP-11 instruction set |interpreter does not simulate hardware floating point. COMMERCIAL POINTERS: From: G B Reilly <reilly@scotty.dccs.upenn.edu> |Subject: My company translates MACRO-11 to C | |We just finished an assignment in Switzerland to convert 250 000 lines of |MACRO-11 and are currently working on a similar project for a company in |New Jersey. | |Can we help? From: fred@Sun.COM (Fred Zeise(SPD-systems)) |The RT-11 system macros would be the main problem: There is no UNIX |analog to .CSIGEN but most of your translation could be done by a macro |processor to take PDP-11 assembler input and output SPARC opcodes. | |Failing that OMNEX a small DEC/UNIX consulting house at 415-866-8400 in |Mountain View might be interested in helping develop the tools.
