@jacgoudsmit Thanks for commenting! Yes, DOS is running but without most of the external commands that make it functional. I hadn't considered the disk interleave as yet -- just getting those drives to work was quite the adventure! I found a supplier in Toronto that had "new old stock" that was kept in a hospital engineering department as spares for their original batch of PC's... Some corrosion but little wear. Not sure about the left/right placement of drive A -- I've seen them both ways!

Technically you have DOS running all the way: DOS is really just IBMBIO.SYS, IBMDOS.SYS and COMMAND.COM and that's what you have.
It sounds like it's taking a long time loading DOS, possibly because of interleave problems.
Good job on finding those single-sided drives(?). Our first IBM PC 5150 (1984) had dual sided drives and ran PC-DOS 2.0. Also, I'm pretty sure the LEFT drive was A: in our system.
Love the monochrome monitor with the high-persistence phosphor. Brings back memories!
