+Information about Lotus 1-2-3
+-----------------------------
+Lotus123 comes with 2 cartridges and 3 floppy disks. None of the disks are bootable, so a pcdos boot disk has been
+included. Since the computer only has one floppy, you need to use Mame's File Manager to switch disks as needed.
+Please note that most actions take quite a while to happen.
+
+Start the emulation with >mame64 ibmpcjr lotus123
+Wait for the floppy to boot, and answer the questions about date and time. The carts add 3 new internal commands:
+* TUTOR - to use the tutorial, select the Tutorial disk, then type in TUTOR. After a while it will start up.
+* 123 - this is the direct way to use the Lotus 1-2-3 spreadsheet program. To quit, press /QY .
+* LOTUS - this starts a menu where you can select various utilities.
+
+The lotus utilities:
+1-2-3 - you need to select the Help and Utility disk, then choose this option.
+File-Manager - select whatever disk you want to manage, then choose this option.
+PrintGraph - this option doesn't work because the menu thinks that there's not enough memory.
+Translate - this option doesn't work because the menu thinks that there's not enough memory.
+Exit - back to DOS.
+
+Printgraph and Translate can be run from DOS.
+- To run PrintGraph, select the Printgraph disk, then type GRAPH.
+- To run Translate (a file conversion program), insert the Help and Utility disk, then type TRANSLAT.
