Posted by jpluimers on 2014/03/15

The BitSavers /pdf/apple/apple_I directory now contains a PDF of the Apple I Cassette Interface Documentation.

Awesome history (:

It even has this very old Apple address on it:

 

APPLE COMPUTER COMPANY
770 Welch Road,
Suite 154
Palo Alto,
California 94304
Phone: (415) 326-4248

If you try to upgrade the virtual hardware of your VMs to the new revision 10 after you have updated the host to ESXi 5.5 then the following warning will be displayed by the vSphere Client:

“If you upgrade the virtual hardware to this level, use the vSphere Web Client for managing these VMs.”
