First two systems were floppy drives only - wasn't until purchasing a Northgate 286-based system that a HD was included.
Do not remember what the HD added to the cost, but it was a MicroScience 60MB RLL drive: 50% more storage and faster data access than the more common MFM drives of the time (most competing systems installed 30 - 40MB drives).
First REPLACEMENT HD that we purchased was 250MB. Do not recall manufacturer, but do remember being tickled that cost was BELOW the "magical" $1/MB price point (!

) - which is also referenced by one of the earlier posts....
