IBM 370/360 software package for developing stand alone LSI-11 systems
A software package for the IBM 360/370 system at SLAC was implemented for use in the development of stand alone LSI-11 software systems. Included in this package are the following: XASM11, a cross assembler which handles a substantial subset of MACRO-11; PL-11, a cross compiler for a structured programing language designed around the PDP-11 instruction set; FORTRAN, complied under RT-11 and transmitted to the IBM 360/370 for translation and integration; XLCVT, a conversion program which takes as input standard DEC DOS/RT-11 object modules or LIBR files or object modules produced by PL-11 and XASM11 and converts them to a form suitable for input to XLINK11; XLINK11, a cross linker which takes in relocatable object modules and outputs a DEC DOS/RT-11 absolute loader format module, or a format suitable for an IBM 360/370 PDP-11 simulator; REFORM/EPROM, conversion programs which take as input a DEC DOS absolute loader format module generated by XLINK11 and convert it to a format suitable for downloding into an LSI-11 or for burning into EPROM's; XREF, a cross reference program which takes as input a PDS of XLINK11 type object modules, and outputs cross reference tables and information on each of the modules; WYLBUR execute files, files executed from the terminal to create jobs in response to simple prompts; and KERNEL, a set of MACRO-11 and PL-11 routines which have been burnt into 2780 EPROM's and include a terminal emulator, a down line loader, and several routines for the LSI-11. This work was accomplished by using the facilities already available on the IBM 360/370 system. Most of this package has been in regular use since Spring 1976, although new features are still being added. The manpower cost of researching, organizing, developing, and integrating the tools has paid off well. 3 figures.
