To unprotect the "Smart System Disk", use diskcopy to make a backup, or load all files onto your hard disk. Next using DEBUG issue the instructions listed below: debug smart.com G 12F T G 9F35 T G 31B8 T G C760 T G 22 T A 27 JMP 29 A 807 JMP 885 G Q This begins execution, then modifys the partially executed file. After this process is complete, screen output is restored, and voila, you have it - The Smart System - up and running. I must confess I am new at this - have only had an MS-DOS machine for two months, so there may be a faster way. I am working on it, and would appreciate any help. Leave a message for me on any Bay Area bulletin board. MICHAEL YARD March 10, 1985
