Pickens +RFC # 485 UCSB +NIC # 15063 19 March 1973 +References NWG/RFC #473 + + + MIX and MIXAL at UCSB + +The following, in response to David Walden's MIX query (RFC#473) was +written by a graduate student at UCSB. Questions regarding "cheap" +usage should be directed to Roland F. Bryan (RFB) at UCSB. +----------------------------------------------------------------------- + +Mark Scott Johnson +18 March 1973 + + I wrote a MIXAL assembler and a MIX simulator last summer. The +assembler is written in SNOBOL4 and, unfortunately, is fairly expensive +to run. The assembler has been fairly well debugged and is documented. +However, although the MIX simulator is written (in 360 Assembler), it +has only been partially debugged. Due to the resumption of school and +other commitments, I was unable to give the simulator a thorough +debugging. All the simulated instructions except I/O instructions have +been tested somewhat and appear to be operating well. Also, card reader +input and printer output are operational, but my simulation of disk +files and magnetic tape has not been completed. There is presently no +documentation for the simulator. Very little documentation is needed, +however, since the simulator follows almost to the letter the +specifications detailed in _Fundamental_Algorithms_. + + If anyone is interested in using the assembler and/or the simulator, +I will be happy to supply what documentation exists plus some +information on how the programs can be accessed. Also, if anyone is +interested in the source code for the programs, I will be happy to send +it. I hope to be able to finish the simulator this next quarter. If +anyone wants to use the system and if they should find any bugs, I will +do my best to maintain and correct the programs. + + + + + + [ This RFC was put into machine readable form for entry ] + [ into the online RFC archives by Alex McKenzie with ] + [ support from GTE, formerly BBN Corp. 9/99 ] + + + + + + +Pickens [Page 1] + -- cgit v1.2.3
