Yes, I have a 128 and a 512k macintosh. Do you think that a 800k drive from a Mac Plus -less value than the 128 or 512 ;)- will work, at least as a 400 k drive ?

I saw the presure Pad, seems to be OK.

In fact, the drive don't spin, or try to spin then go off, and Lisa eject the disk with Error 23 or IO board error 39 (timeout).

This is done with both IO card.
