Another silver label. Finally got all “three” silvers complete. The early 250407, ku and the 326298 board. The Commodore registry shows that those three assy’s with a silver label exist. Untill today it’s not perfectly clear if the silver label was only produced with the buggy 326298 board, and that all other silvers with 250407 and ku boards are simply RMA replacements of faulty 326 boards. Might be a case of Commodore Europe just producing silver labels and finishing stock of labels, producing them even on the early 250407 boards. Later on they started producing rainbow labels and switched silver labels for rainbow labels if a Commodore 64 was send in for repairs. Anyway mission completed.
Now, if we look closely at the Commodore registry at the silver wgc boards, than most serial numbers in this range are early 250407 boards. Between serial number 20.000-30.000 in all three production lines, in the WGA and C lines, only one per line is registered. In the WGB the numbers are quit higher of registered units: 10.
If we look at the rainbow labels of these three production lines, within given serial number range, 3 KU are registered in WGA, 1 in WGB and 1 in WGC.
In the end we cannot conclude or exclude anything, is this an original?. Who knows. Is this a very very late KU board, while most units produced were already in the early 250407 assy’s? Or did just someone replaced boards…
