Hi folks. I unearthed an HP87XM from my storage area and have been
thinking of firing it up as a little diversion. Can anyone point me
toward any programming reference info?
Also...what are my mass storage options on this machine? It's got
an HP-IB interface, and I've seen lots of HP-IB drives over the
years...but what were commonly sold with this machine?
Thanks,
-Dave

You need to use drives following the AMIGO protocol. Here are the possibilities:
Floppy drive models
82901M (5 1/4" AMIGO dual disk)
82902M (5 1/4" AMIGO single disk)
9121S (3 1/2" AMIGO single disk)
9121D (3 1/2" AMIGO single disk)
Hard disk drive models
9134A (5MB AMIGO HDD)
9134B (10MB AMIGO HDD)
9134XV (15MB AMIGO HDD)
Combo models
9133V (5M AMIGO HDD, 3 1/2" single disk)
9133XV (15M AMIGO HDD, 3 1/2 " single disk)
**************
Many of these are regularly available on eBay and do not usually run much over $25.

Here are the possibilities:
IIRC, if you get the "Extended Mass Storage ROM", you can then talk to
CS-80 disk drives.

Hey! Carefull there. That's the number for a HP 85 ROM. It wouldn't work
in your 87. AFIK all the HP 86 and 87 ROMs all have a 00087-xxxxx part number.
but I've never been able to find one. Anyone have or ever

I have heard that these exist -- I think the ROM number is 00085-15013 -- seen one of these?
I had one I'm not sure that it's still around. I'm pretty sure that I
still have the manual for it but it only has two commands and at least one
is the exact same as the standard 87 command except with the EMS ROM now
allows the command to work with CS-80 drives instead of only Amigo drives.

Yes, that's right, I meant the 00087-15013.

Commonly used a 82901/82902 5 1/4" floppy drive but a 9121 3.5" works
and is much faster (Hint: you HAVE to use 720k disks in the 91xx drives, a
1.44 disks will not work). I MAY support the 9122, I'm not sure. I think
it will support the 9153 hard dive. It will also support the 9895 8" floppy
drive. The 87 XM is a fine machine, and was the top of the line for the HP
85 series.
