Dear all,

the long and fearfully awaited day has now finally descended on my
laboratory. The Apple IIe, so far bravely controlling our MAT 251,
has stopped talking to the instrument; the IEEE interface card inside
the Apple has ceased to perform and this, of course, renders the
whole mass-spec unusable.

Naturally, the first idea coming to mind is to put a PC onto the
machine, but there is no suitable software available here in South
Africa. I would like to at least test whether an old DOS version of
Isodat works on my old MAT 251.

Any suggestion of how to sort out this problem will be welcome;
ideally, I would be looking for someone who may have had a 251,
done away with it long ago, but may still have the old CDOS / Isodat
software somewhere in a long forgotten cabinet and would be willing
to part with it. Needless to say, there is no support by the well known
manufacturer of this instrument any longer.

Thank you all
regards and cheers,
Uwe
