  • I have a AppleColor RGB monitor new in box model A2m6014 Ser# n8455466 what is it worth

  • This web page is confusing the AppleColor RGB Monitor (A2M6014) with the AppleColor High-Resolution RGB Monitor (M0401/M1297). They are absolutely not the same display and only resemble one another externally. The former is designed for the Apple IIc / IIgs and the latter is designed for beige Macs. Even the signal configurations in the DA-15 connectors are different.
