we have a Goodway GT-25 lathe that runs Meldas Magic 50 PC based controller software running under windows 95
It appears that from searching the web that the Magic 50 software and associated controller card ( RS611A - BN634E704G51 ) were only made by Mitsubishi for a couple of years then superseded by the Magic 64 control system and software.

Our system will now not recognise the controller card on power up and the PC Controller card onboard LED Display now displays -2 after being powered. ( Before it was 8 when running OK)

I have searched all forums and Mitsubishi databases but cannot fine any supporting documentation at all for the Meldas Magic 50 PC controller.
We have restored the controller PC Hard disk from a known working image but with no luck.

Can anyone help with advise or documentation as to what the -2 card display means or how to check the card device driver.

Thanks in advance
