Good day,

I'll do the short version first, then the detailed one after:

I need a GPIB to RS232 or USB interface.  I've only seen multi-hundred
dollar boxes on the web, and have to believe that someone has cooked up
a piece of AVR (ideally, or PIC) code that eats GPIB and spits out one
of these formats.  Maybe there's a Windows driver that fools the OS into
thinking a com-port is GPIB, or maybe a terminal-like thing that lets me
type raw GPIB commands...



Detailed explanation (or, what I'm _really_ trying to do):

I have this old piece of Tektronix gear that plugs into their analog
7000-series scope mainframes, called a 7D20.  It is a 3-slot wide plugin
that is basically a digital scope that uses the mainframe for power and
display.  It is two channel, each 70MS/sec, which is plenty fast for
much of what I need.  And it also has this GPIB port on the front...

The tricky bit is that I have no PCs to plug a cheap ISA or PCI GPIB
card ("eBay specials") into; I use a Mac laptop at my bench, and run
VirtualPC when I need to, with an RS232 -> USB converter.  It would be
exceedingly inconvenient, verging on impossible, to have an entire PC
dedicated to GPIB.  If anyone can point me towards something that can
assist in getting data from the scope to the computer (if you're about
to say "digital camera", I'm there right now!), I'd love to hear about
it.

Thanks!
