  I'm also looking for an HP Extended Mass Storage
module (hp 00085-15013)
 for the HP 85 (A/B).  I'm trying to get an old disk drive (hp 9133 D) to
 work with an HP 85 B.  [...] If you have an HP 85B then you *need* the HP 85
version of the ROM,
the HP-87 version will not work.

This ROM is EXTREMELY rare, so don't bank on finding one. Its probably
better to try to find an older drive (e.g. the HP 9134A/9135A hard drive)
rather than trying to get your HP-85B to work with the newer drives.

If however, you do find an EMS ROM, please let me know. I'd like to
try to get a copy of the ROM image so that I can xfer it to
an EPROM and then try to interface this to the HP-85 bus (non trivial
since its 6V based).

Best Regards
