>From wetware memory (may be faulty), serialization is in the bootloader and not the kernel. Uniplus file system starts at block 100 and the os itself cannot see blocks 0-99 via dd. But BLU will see the whole disk. Serialization works like this. The Lisa's serial number is read and mixed with a pseudo random number, a crypto hash is done using the old Unix rotor crypto and a key is displayed. You'd then call unisoft and they'd give you an activation code. That would be written into the boooader. When the system starts it would check the Lisa's serial vs the activation code and either boot or die.

You should be able to replace blocks 0-99 from a cracked system and boot anyway. I think the Uniplus images on bitsavers already have the crack built in. Might even work if the versions are different. If you do have personal stuff on there and have rm'ed it, before do: dd if=/dev/zero of=deleteme; rm deleteme before you image it with BLU to zero out the unused data. You will need to do that on every partition that had personal data. If uniplus lacks /dev/zero do: yes | dd of=deleteme instead. I think the 6 page booklet is on bitsavers but as HTML or text rather than a pdf. Also, Gilles has a 10mb uniplus image here:http://alternative-system.com/files/lisa_emulator/binary/profile_uniplus.zip :)

1999 in that video. How is UniPlus able to specify a system date later than 1995? What happens if you set the date to 2000/01/01? :-)

Do you think you might ever be able to share your ProFile image? Maybe if you delete the personal items... We can out deserialisation and swap configuration issues :-)

" Well, it just so happens the Lisa I recently obtained has UniPlus loaded on its Profile! While I was still at the seller's place I used BLU to clone the 10mb Profile onto a 10mb profile partition on my IDEFile. Now that the Lisa is repaired enough to function, I was able to try booting it up. It came up with no problems (other than the swap partition being too small for the 1.5mb of ram the system has now) The bootloader it serialized. There is a paper note taped on the top of the Profile, which gives the command to boot the system from the bootloader prompt:W(0,2501)UNIX Here's a quick video I took of the system booting:https://www.youtube.com/watch?v=8sibMWe7xgY

This system was used by a VT student... I found some of his homework on the hard drive, and a copy of his Freshman through Junior year report cards! When I get home tonight I'll use BLU to pull a file image of the ProFile. Is there anything that the group would like me to check on this system? The only documentation I got with the system is a ~6 page into booklet. I don't see it on bitsavers, so I'll scan it. Thanks,

I haven't touched it. I won't until I can get set up with an A/UX 3

install, or, failing that, something else that can pull a best-effort

image of the A/UX partition from the failing drive. (I'm hoping to

get the partition mounted as an A/UX filesystem, as I'd like to

recover the personal information from it with a somewhat higher

priority than the rest of the data.)

I'm interested in preserving the A/UX 1.1 distribution, but not to the

extent of paying for a full clean-room data recovery. :-/ Like

UniPlus on the Lisa, though, it may still exist as closetware --

sitting on the drives of Mac II's tucked away in the closets of 1991

Va. Tech CS graduates. Most will have been reformatted and/or tossed

by now, but some may still exist.
