Lotus 1-2-3 1A
Released in 1984 by Lotus Development Corporation
ROM cart for the IBM PCJr.

As odd as it may sound, Lotus produced a 1-2-3 ROM cartridge for the
IBM PCJr. This archive includes a ROM dump of the cartridge.

This can be used with an emulator such as MESS version 148 (Note,
MESS PCjr support seems broken in version 149 and possibly later)

To use it with MESS:

- First you will need the lotus123.zip ROM ZIP file, and an IBM
PC-DOS 2.0 floppy disk image. (Other versions of DOS may not work.
Also, MESS will crash if you omit the disk.).

- Put the lotus123.zip (do not change the name!) file in your ROMs
folder, and put the PC-DOS 2.0 360k disk image in the software
folder.

- At a command prompt in the MESS v148 folder, then type the
following: "mess ibmpcjr lotus123 -flop software\dos2.img"

Where "dos2.img" is your PC-DOS 2.0 disk image.
Note that you do not specify a path to the ROM file.

- Finally, when the emulated PCJr is booted to a PC-DOS 2.0 command 
prompt, enter "123". Even though that is not a file on the disk, it 
will start the Lotus 123 application.
