Possibly a hardware guru can tell what the undocumented B1-03 (E13) is capable of...?

E13 (or E11 on 100-A) is labeled '256 x 8 arbitration ROM' and soldered directly to the motherboard.

The schematics from 100-A is a bit clearer on this:
(note the difference on pin 5 when compared to 100-B ).

Unfortunately, it is a small chip in a confined space.

Will we get away without it?

blush OMG...i am talking to myself
