Memory Lane...

I remember this ad, which ran in one of the computer hobbyist magazines in the late '70s (probably Byte).  I remember thinking how amazingly inexpensive that system was.  Just a couple of years prior, I had purchased a used, broken Memorex 630 for $10,000.  I spent a month or so troubleshooting and fixing that thing, and ended up with a washing-machine sized 10 MB hard disk (5MB fixed, 5MB removable).  I had to build a computer to interface with it.

And IMSAI was selling a complete system with a miniature “Winchester” hard disk for just $6,000.  Cheap!
