Does anyone know where I might find a HMM for a PowerPC 820?

Have not seen an hmm for the 820, but do remember seeing one for the 850

oh, remember where I found it:
http://www.ibmfiles.com/

They do seem to have some info and files on the 820, but no hmm

EDIT: Dunno if this can help your further search, but they list some option order IDs for the hmms (from the original hardware announcement):

Erhmm.. can't believe I didn't see that before.

If you jump over the Thinkdan's thread here:
https://forum.thinkpads.com/viewtopic.php?f=6&t=135334

look at the 4th image

..maybe he could share some scans or photos of it?

Here it is, happy for it to be added to the forum's HMM page.

I scanned it as a 200dpi greyscale as the copy I have (ordered from IBM publications circa 1999) was supplied as a photocopy of an original. The diagrams looked awful on mono scanning.

Can do the 850 HMM also if required, although a scan of that already exists.

So if you are asking for the HMM does that mean you have one??

Post pictures!

ThinkDan,

I would've scanned that photocopied book in grayscale mode at 300 dpi (or higher), run it through ScanTailor Advanced for post-processing (page-splitting, deskewing, etc.), then convert it to PDF.

Got your 820_HMM, thanks.
I just uploaded it, together with my own 850_HMM to the Forum.
You can find them under the HMM link as:
ThinkPad 820 Power Series
ThinkPad 850 Power Series

Thanks, I'll have a look at that
