There seems to be a "de facto" standard, which is to clone
the National Instruments cards and software. The Brain
Boxes manual mentions a "GPIB.COM" device driver which
makes their card work with the NI applications.

Yes, but the drivers' APIs may be fairly standard.

Software that uses the MS-DOS "GPIB.COM" driver may work,

I'll give it another try as soon as I have all the right
things set up. My PET disks are stored underneath my PET,
which is behind my DEC LN03R laser, which is under a bunch
of stuff put there to make room for a BBQ over the
weekend... :-)

Where can I find out about this DIY IEEE card?
