[Coco] 24-pin ECB ROM Part #

[Joe Grubbs]

I can check when I get home. FWIW, I do have a Tandy house-marked ECB 1.0 ROM from a CoCo1 stored away in an anti-static package. If you want it, I can bring it to the fest.

> 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.
