The ROMs are for the 5373, not 5372. I didn´t check the HP part number, but
checked the part id: AM23C010-200, 128Kx8.

I don´t have a 5372. I used several boards of a 5372 (A3, A4, A5 and A6) to
repair my 5373,
 that is working fine now.
I do not have any information on the processor boards, however.
