I just got one of the ZoomFloppy USB converters with the HPIB interface included. I
decided to get that one because of all the open source USB to HPIB converters, it was the
cheapest. However so far I can't find any information that anyone has used one to talk
to anything except Commodore GPIB devices.
Right now I'd like to see if it's possible to use the ZoomFloppy to read from my
old HP 9133. After that it would be nice to see if I can use it to diagnose the 7958 where
the fault light comes on. My ultimate goal is to be able to use the ZoomFloppy to emulate
an HPIB disk drive, either with the HPDrive project or something else.
I don't have the time at the moment to try to write any software and I'm hoping
someone else has tried it and can give me some pointers. If there's really nothing out
there I will probably try to write my own software, but I don't know how soon I can
get to it.

Chris,
I'm not familiar with those USB-HPIB converters but, can tell you a good bus
analyzer is invaluable. I've used a HP59401A to talk to a drive like the
7963 and it worked great. They show up on quite often on ebay and are
usually reasonably priced. As a matter of fact there are several on there
right now.
NOTE: I don't know any of the sellers or anything other than what is says
in the ads but, it might be something worth looking at.
Working HPIB drives are becoming much harder to find. I used to find them in
the scrap yards for a few bucks apeice but, haven't seen any in quite a long
time. At one time, I probably had 50 of them. I still have a few but, since
they are hard to replace, would rather not part with them.
See ya,
Steve Robertson
