Was curious if anyone here has - or knows someone who does - a Xebec 1402A
Seagate HDD controller. The drive is in an IBM 5150. Note that this MUST be
the 1402A, NOT the more common 1402. There is some important historical
data we are trying to recover, but the controller is nonfunctioning.
Thank you for any help!

This may a dumb question, but could the drive be imaged by some other means, such as David
Gesswein's MFM emulator?

The 1402A was in error ? it's a 1410A with version 1.0 firmware.

I have an as yet untested CoCo hard drive system from eBay with a 1410 in it. Sadly, not
the 1410A that Jason says he needs. The 1410A manual at Bitsavers notes some
incompatibilities including incompatible formats for 256 byte sectors, so I presume that
Jason has already determined that an older 1410 won't work for the recovery he's
attempting. :(

I'm having a little trouble following this thread. You mention a "1402A",
but another person posts "..it should really be 1410A". Which are you
looking for?

We are looking for a 1410. The 1402a was a miscommunication on the part of
the original person.

The machine is an original IBM PC, correct? Do you have the requisite
host adapter to interface with the 1410A bridge controller?
The 1410A was shipped with a number of different firmware versions. Do
you know which one you need?

We do and the firmware revision is 1.0. I'm sorry for feeding this
information out in drabs - I thought it was asked in the original mail and
apparently not.

Please post any and all numbers on the 1410A board ROM. That's the only
way to understand what you have.
