I have hundreds of BASICA 3.0 programs that are currently being executed on my systems (Dual-diskette XT, XT286, and PS2Mod35), none of which I have been able to execute on any later system (I now need the increased speed and disk space not previously available). I run on IBM-PCDOS 6.2 (and lower during compatability testing). What is happening on my newer Pendium III systems is that BASICA immediately goes into limbo as soon as it is invoked - no keyboard data is received nor any displayed - and the cursor is lost until I kill the BASICA execution. Can anyone out there tell me what is going wrong and how to fix it. I tried going through IBM service but they want me to purchase a service contract and that, as a retiree, is financially unfeasible. I'm still trying to save up enough to purchase their IBM-PCDOS 2000 (which they can't so much as tell me if BASICA is compatable with). Thanks - any explanation will be greatfully acknowledged.
