shortname: 'Ampro Little Board' comment: 'CP/M' read_support_status: DINOSAUR documentation: <<< The Ampro Little Board was a very simple and cheap Z80-based computer from 1984, which ran CP/M. It was, in fact, a single PCB which you could mount on the bottom of a 5.25" drive. [All about the Ampro Little Board](http://oldcomputers.net/ampro-little-board.html) It stored either 400kB on a double-sided 40-track drive or 800kB on a double-sided 80 track drive. The disk format it used was a slightly quirky variation of the standard MFM IBM scheme --- sector numbering starts at 17 rather than 1 (or Acorn's 0). FluxEngine supports this. FluxEngine has direct filesystem support for these disks, or you can pass the disk images into [cpmtools](http://www.moria.de/~michael/cpmtools/): ``` $ cpmls -f ampdsdd ampro.img 0: -a60014.e amprodsk.com bitchk.doc bitchk.mac cpmmac.mac dir.com himem.doc himem.mac kaydiag.lbr kayinfo.lbr ...etc... ``` >>> documentation: <<< ## References - [The Ampro Little Board](http://oldcomputers.net/ampro-little-board.html) >>> image_writer { filename: "ampro.img" type: IMG } layout { sides: 2 layoutdata { sector_size: 1024 physical { start_sector: 17 count: 5 } } } decoder { ibm {} } filesystem { type: CPMFS cpmfs { filesystem_start { track: 1 } block_size: 2048 dir_entries: 128 } } option_group { comment: "Format variant" option { name: "400" comment: "400kB 40-track DSDD" config { layout { tracks: 40 } tpi: 48 } } option { name: "800" comment: "800kB 80-track DSDD" config { layout { tracks: 80 } tpi: 96 } } }
