Don’t you think that may have been kilobytes?

I don't know if you were just joking, but 20 MB and 40 MB would be correct. Heck, a typical 5 1/4" floppy diskette in '86 was either 360 KB (DS/DD) or 1.2 MB (DS/high density).

The reference hard drive in those days would be the venerable 20 megabyte Seagate ST225. The 40 MB version was the ST251.

There were MANY other brands in those days, but Seagate was the dominant player for a low headache, OK performance option. It was still MFM, which wasa pain to set up, and much slower than newer xIDE and various flavors of SCSI, but MUCH faster than a hard drive or other solutions (e.g. Coleco Adam's Digital Data Pack).

You’re correct. I was confusing my pc experience with my timesharing experience with a GE 400 mainframe which had a RAM core measured in kilobytes instead of megabytes.
