If your old IBM PC IEEE 488 card is one that is compatible with HPDrive 
http://hp9845.net/9845/projects/hpdrive/ you can use it to emulate a 
wide variety of HPIB storage several of which are compatible with the 80 
series machines.  I am using the Linux version on a Pentium II based 
industrial computer with ISA National Instruments cards and it out 
performs a real 9135C by quite a bit.
