Visual Basic Question

The interface is an ISA bus card that is a custom design.  ISA slots in 
computers are hard to come by these days.  Luckily for me I ran into a 
Gateway in a thrift store that did.

I have some of the diagnostic routines and they run under Windows 98 and 
'talk' to the spectrometer via the interface card.  I suppose it is 
using the same low level driver.

In the published literature of that era (1990's) I found a couple of 
references that said they used Visual Basic to get data for experiments.

If they directly access the hardware then they will not work on any NT based windows such as Windows/2000, Windows/XP, Vista, or 7, 8 or 9. Nor will they work on any 64-Bit windows full stop. 64-Bit windows does not support 16-bit code. If you have a Windows/95, 98 or ME environment then the code may work.
