Olivetti Luggable Questions

All, I was recently given an Olivetti luggable. http://personal.nbnet.nb.ca/gallante/olivetti.html links to a page on the same model machine. With a bit of work the system is running well, it has cleaned up really well and looks to have been lightly used at best. The insides were VERY clean considering its age and the conditions it had been stored in. There is no burn on the CRT and the display is clear and crisp. :) The motherboard is labeled 'Corona Data Systems' and is serial number 0160. Various dates indicate the system was built in 1983. I find several references to 'Corona Data System', it appears they were sued by IBM and lost over copyright infringement. I'd be curious to find out if this system is one of the ones that infringed on IBM's copyrights. At boot it POSTs the following: ROM Version 1.53 Testing Complete 512K Memory Installed 512K Memory available to DOS I've been able to boot several versions of DOS, and have formatted a set of working disks. :) I'm looking for more info on it, searching the web only provides the one link listed above. -Neil
