I just found four spiral-bound booklets of Kam Plus related documentation. One booklet is the Kam Plus Reference Manual, it's surprisingly good documentation. The other three are software manuals for the Hostmaster II+ software than Kantronics sold. Happy to send the documentation to you no charge, it ya want to throw me a couple of bucks for postage the XYL/shipping agent would surely appreciate it. If you have no interest, let this thread know and we can let someone else have it. You probably could find the Hostmaster II+ software if you looked around for it. It's been a while (many years) since I used Hostmaster it but I remember it as being OK, decent but not stellar, at least for the time period.
