Anyone have ROM dumps from a Pro-Log M900 ?

I'm working on getting one up and going - possibly a ROM or 2 are in the wrong positions or have invalid.
Would be nice to confirm.
Thanks!

0 1 2 are the critical ones. there were lots of options
what i have is at http://bitsavers.org/test_equipment/prolog/m900/unit_1

it would be really nice if the firmware was archived.
people just seem to be busy ripping them apart for the 4004 chips and tossing the rest

Excellent, thanks!
I'll dump mine soon and take some more photos.

For future searchers -

ROM dumps and lots of photos of my M900B here:

Had to replace a number of bad 74C175 chips and one SRAM chip, the unit works well now.
I used 74HC175 as replacements.

I made a lucky find. I got a M900 with two adapters,lots of documents. It even still has the 4004 and two RAMs. These are not particularly valuable,being grey ceramics. Might be NSC and not Intel ( getting dark now ). I'll see what it takes to get it working. I'm hoping it will do 1702As and up to 2716s. Time will tell.

No 1702s programmed. The two modules it has are 2704/08 and 2716. Now to see if it powers up. I don't do many 2708's bt it looks to be handy. I've another programmer that does most of the 5V only EPROMs.
