New: The Altos 5-15AD microcomputer is a "multiuser" Z-80 based machine This machine has 192K of RAM, two 800K 5.25" floppy drives (700K formatted,) three serial ports and a parallel port.  This machine supports three simultaneous users, under MP/M-II.

I received this machine with a floppy diskette containing the OASIS v5.6 Operating System.  I was unable to crack the system password for this operating system.  I have provided a TeleDisk v2.15 image of the OASIS boot disk here.  Please let me know if you figure out the system password.  I will be happy to put the OASIS 5.6 disk in the machine for anyone who wants to try and hack into it via the Internet.

Some additional boot disk images for the Altos 5-15AD are available below...
