plgDavid: sure thing. From a quick look at your scans, it's possible that the '11 has a TMS1100 and the '24 has a COP4. If that's the case, they might both be electronically dumpable. But the TMS1100 could be a revision that we can't get all the bits and output OPLA out of, or it might even be a variant that we don't know how to dump electronically (the 09x0s).
Do you know what the two 20-pin chips are on the '11?
