The ROMs appear to be the three N82S181 right underneath the CPU. My eprommer can't read them, though. https://www.westfloridacomponents.com/mm5/graphics/L11/82S181-BJA.pdf

Great link, Edstrom, thanks!
I'm not too keen on de-soldering the PROMs, but I've had good success with clamping a socket over the IC's legs ... I'll get sockets and try to remove the board from the DMV ...

Got the board out, but can't read the PROMs the easy way  It's a WD1001-05 Rev. A12

According to this site, http://www.prof-80.fr/wd1002-05-controllerin addition to the Kaypro 10, the WD1002-HD0 from the external DMV kits is also used on the TRS-80 1, III and IV. From a MAME perspective, what would the WD1002-HD0 need to become to be usable by all the different machines? A device? What would be an example of that? As for the WD1001-05 from the internal kit, can anyone, preferrably in Europe, read the N82S181 ROMs and perform the soldering?

Was anyone ever able to do this?

If the board was sent here I could desolder and dump the proms...

LN, if you send me a pm with your address again, I'll ship the WD1001 to you next week.
