I had a CMS 30 Meg HD which I upgraded to a 340 Meg Maxtor
drive.  The one the dealer ordered for me originally was a SCSI 2
Quantum drive but it wouldn't work in the CMS enclosure.  I then
had to exchange it for the Maxtor drive for the SCSI 1 support.

I believe it was a Quantum LPS that I couldn't get to work with the
Mac Plus.

I paid $799 US for a 30 Meg CMS drive in 1989 for the Mac Plus.
The 40 meg Apple drive was like $999 or something like that.  I didn't
think the 10 meg was worth the extra money.  I believe the 20 meg
apple drive was $699 at the time so 30 meg was a decent compromise.
All told, I think the Mac Plus with HD and Deskwriter cost me about
$3400 US (Mac 1699 + 799 printer + 799 HD + tax).
