  HP's number for this OEM board--by MSC/Xebec
is 88134-69910, 09135-69515, 
 and/or 09135-69501. I have no idea which number belongs to mine.

 FYI: These are all used on 5Mb drives with two sets of firmware classified as follows:
 88134-69910 'L' Code - HP250 Model 20 
 09135-69515 'D' Code - 4-Volume 5-Mb (emulates HP 9895A drives - I use this for
my 9845B and HP-85 & 87 systems)
 09135-69501 'L' Code - single volume 5-Mb.

    Thanks. That's useful.

Now if only I knew what the Xebec part numbers were for the HP
models/firmware...

I have four different sets of Xebec firmware. Two of the sets have the
"D" or "L" formats, selectable by jumper.
One of those two also works with 10Mb disks but will only format the
10Mb as 5Mb or the 4-volume "D" format. 
AFAIK HP only used the above three (MSC) controllers (for ST506), after which they
designed and manufactured their own controller for their 5 (ST406), 10 (ST412)  and
15Mbyte (ST419) Winchesters.
For what it's worth, the HP controller number for their 913xB drives is 09133-69514.
For 10MByte: J6 Pins jumpers (10M, One Volume and 4XX) are all installed. I've no info
on The 15Mbyte configuration.

Hope that helps, 
Martin
