Rumor has it that Paul T. Barton may have mentioned these words:

Except 27128's are 28-pin (as are 2764's)... If it holds 8K, it might be a 
Motorola 68764/68766 pinout. These were used on (at least some) CoCo1's and 
2's. I don't know if there were 16Kbyte ROMs in a 24-pin package.

I still have a metric buttload of Moto 68764/6's in several different 
access times if anyone needs any...

Laterz,
