Description

Replaces the PROM that is used to convert pixel colors represented as a 4 bits value (pastel, red, green, blue) and a supplemental bit for blanking signal, into a RGB-222 value and a supplemental trigger signal for the builtin analog video incrustation feature (requires a specific extension) of the Thomson MO5.

2. What should you know before using Replacement of I03 (color PROM) for the Thomson MO5 ?

Replacement of I03 (color PROM) for the Thomson MO5 is made of an hardware part to hold a GAL16v8 (or its current available compatible component ATF16v8) hereafter called "GAL", and a fusemap to be flashed onto said GAL.

• The hardware part is a Kicad 8 project describing the adapter from original chip socket in the computer motherboard
• The fusemap part is a source to be compiled by relevant tool to obtain a suitable JED fusemap.
