Well done for scanning the manuals
I run the RM Nimbus software archive - which isnt publicly avalible, but we are happy to send out disks images on a request basis - mainly as we havent got the clearance from the numerous companies involved in making the software to make it public - we are also massivly restricted on bandwith as well!
Back to Lego! - We do have Control Lab V1.3 for DOS and Windows 3.x for IBM machines - fs this is on any help to anybody. Send me a PM if you need a copy? I also have a copy of 'Lets Go' disk for control Lab V1.2. We also obviously hold the Nimbus Version of Lego Logo
