Archive.org thinks it existed for one day in 2011, but doesn't have a copy.

Via Google: "I utilized Lazarus to create a graphical oscilloscope GUI 
with great success. The hardware of the oscilloscope was a ISA card I 
created myself." So I don't think this would be very helpful unless you 
had Felipe's custom card.

What sort of hardware are you trying to control- something like a 
conventional 'scope (Tek or whatever) or a low-cost capture pod? In the 
past I've captured a dump from a handheld Tek (but I can't remember 
whether there was a control facility), and I can talk to an HP protocol 
analyser... but it would not surprise me if the protocols involved are 
completely model-specific.

As a word of warning, we've got (what used to be) a high-end Tek which 
of course has IEEE-488, there's also something that /looks/ like an 
RS232 port on it but it's actually high-speed TTL parallel, so I'd warn 
you to be sure before connecting to anything for which you don't have 
the documentation.
