Thanks to Sand's recent Mixed Up Mother Goose
submission, it brought to our attention the Tandy 1000 SL/2. We are missing an early 80s config and I think this would be perfect for it. It has MS-DOS 3.30 built directly into the ROM, so it doesn't require any bootable drive to work. It should be able to run any game that can run directly off the floppy, and I've confirmed it also works with the self-booting IBM PC game disks. This would be a much simpler setup than the other configs, essentially only needing the config file and the game disk(s).
Here's what I'm thinking, based on Sand's config and the SL/2's specs
Machine:  Tandy 1000 SL/2
CPU: 8086/8 MHz
Memory: 512 KB
Display device: Built-in video
Sound device: None (would just be PC speaker)
HDD: None (unnecessary with ROM)
FDD1: 3.5" 720k
FDD2: 5.25" 360k (did not come with this, but can be added)
The only thing we would need to supply is the .cfg file. There is some NVR (/nvr/tandy.tandy1000sl2.bin) but it isn't really necessary for what we're trying to do, and can be deleted.
