All true, but you do need a 4bit machine and alas I have 32bit on both my desk and laptop PCs.
In fact nearly, if not all software now seems to need 64bit and not backward compatible. I cannot accept files from those in my model engineering club using newer software as they cannot save back to the Chalk and Slate versions.
Of course, as with most things, spending more money would cure that problem. But like most of us I guess, those pesky $$ are not growing on the tree in our back yard. Not in mine anyway.
