The recent question about MS-DOS reminded me that I needed to get some
things uploaded to the Internet Archive. :)
These two links are disk images for MS-DOS 2.0 as configured for the
Seattle Computer Products S-100 system I have.

The reason I think these might be of interest is that most of the source
code is present and it's designed to use a serial port for the system
console. There's no video board, etc. in my S-100 system. It's MS-DOS
compatible, but absolutely NOT IBM PC compatible. Someone far smarter
than myself could port the console routines to the serial board the
RC2014 uses and build an interesting and unique DOS system.
