Hi all, I've been lurking here since a slashdot article on the 30th anniversary of Maze, the first lan/wan FPS, which was run on an IMLAC. I was very interested in this as I programmed an IMLAC - PDS-4, I guess - in 1977/8 at Sydney University (au) and have good memories of the machine. I saw hints on the list that an assembler was imminent and an emulator was under consideration. That was September 2002, and nothing since. I am really interested in an emulator - I have an emulation of the main processor running and got it loading 'paper tapes' from disk via the paper tape boot loader. I've used this to load code from hand assembled files to test the emulation and I would like to go a little further a little faster. Does anybody have information on the format of the data the papertape block-loader reads and loads? The block loader is the first thing the boot loader runs - it reads in the rest of the tape. Also, does anyone know of or has any software (source or binary) on papertape or any other form? I have no idea of the current ownership, if any, of the existing IMLAC software, and I could write an assembler, but it's so much more cool to run the IMLAC assembler! TIA, Ross
