RE: Rally X roms?

Ok they have to be 2532 (and the parts list says 2532). Apparently the
schematic is not fully accurate.

 

Of course I don't have any 2532's on hand, anyone know if there is a way to
restrap the rally x board for 2732?

What kind should I be using. I am getting rom errors when using the fluke
to verify them (3 of the 4 roms are showing bad).

 

 

The schematic says 2716 in 8 positions but the board is only loaded in 4.
The Mame roms images are 4K binary. So I figure a 2732.

 

They are masked roms and I can't be sure as my rom reader is not reading the
"good" rom the way I would expect it to. By accident I set it to 2532 and
the rom read correctly.

 

SOOO, I think I need 2532's even though the schematic seems to say
otherwise.

 

Anyone ever replaced these and know for sure?

 

Thanks,

David
