There is some ready-baked Arduino PROM reader software lying around here somewhere, it would just need minor changes to read the 287. In any case onewatt seems to be a device programmer connoisseur so I would not be at all surprised if he has a programmer / reader which can read BPROMs. If not, there may be one waiting to be discovered in that hoard.

I'm not sure onewatt would be prepared to disturb the 40-year old pristine soldering on the character BPROM ...as it seems to be soldered in, in the first example... to read it out for us. Maybe the one in the second example is socketed?
