Joe,

Please do bring it. I’ll trade you for a 24 pin Color BASIC ROM if interested.

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.
