PC-DOS 0.90 (with MDA and Debugger)
There was no PC-DOS 0.90 product per se. It has been dubbed version 0.90 simply because it predates PC-DOS 1.00 by several months. More information about this preliminary version of PC-DOS can be found at the OS/2 Museum.
Below is an IBM PC (Model 5150) with an original IBM ROM BIOS and Monochrome (MDA) Display that will boot PC-DOS 0.90. A similar configuration with Color Display is also available. The machine is configured to run at 4.77Mhz, so the ROM BIOS memory test has been disabled, since a PC with 256Kb was rather slow to boot.

PC-DOS 0.90 files were distributed on one single-sided (160Kb) diskette. A directory listing of the disk is provided below.
