Hi all,

Does anyone have a copy of the Osborne 1 Screen PAC schematic? I believe it used to be in the online copy of the documentation, but the current versions only have blank pages where the documentation used to be.

Also, are there any current repositories for "Lornes-special-osborne-software.zip" still available anywhere?

It was originalls discussed in this thread - But www.kaypro.net is now dead :( It's about 64Mb in size I believe.

Thanks
David
 
Thank you for that - I now have a copy of the Lornes Special and some other disk images and some clues as to where the Screen PAC schematics might be findable - Not sure if they have digital copies at the museum though.

Just to help those searching for the Lornes special archive to get software to run the screen pac.
I will mention it's not on that archive.

The disk you want is the Osborne extended utilities disk - It's on the Maslin archive.

http://www.retroarchive.org/maslin/disks/osborne/

OS1XUTLS is the disk. You can get it into an Osborne via Gotek or via Greaseweasel and writing the disk
