Can anybody tell me if you can buy an up-to-date software anywhere?

We have such an old version that it only runs on a DOS computer with Herkules or EGA card.
Unfortunately, that computer ‘died’.

The new software should at least run on XP and offer the same programming possibilities like it would directly with the controller.

It would be also good if the a data transmission over the serial interface is possible.

Many thanks in advance

Luis
