> Hi everyone,
>
> I resurrected an old CoCo 1 that was in one of my storage cabinets. It was
> a reject from a previous Fest that I picked up. After taking it apart and
> cleaning both the motherboard and case, then changing out some bad RAM
> chips, it’s purring like a kitten. I even replaced the old MC1741 op-amp
> with a newer TI one that allows me to now use DriveWire at 57.6K speeds
> like a CoCo 2.
>
> The only thing that this CoCo 1 doesn’t have is Extended Color BASIC. The
> motherboard holds two 24-pin ROMs, one of which is Color BASIC. The other
> socket is empty.
>
> Does anyone know the part number stamped on the 24-pin ECB ROM?
