Hi!
My C64 Reloaded mk1 developed a problem yesterday. Pressing one of the keys in vertical line 7 of the keyboard matrix (X, V, N, <comma>, and <cursor down>, but oddly not the <slash> key), results in a clear screen with "Ready." prompt, much like hitting <run-stop><restore>; sometimes the pressed character then appears at the cursor. When I hold <shift> and type any of the aforementioned keys, the expected graphical symbols appear on screen as they should, without this problematic behaviour.
Also, the built-in reset switch (pushing the power switch on the C64R mk1 up from the "on" position) now causes the computer to freeze.
Looking at the schematics I would expect the problem to lie in CIA chip #1. However, after swapping that IC out with at spare that I have showed no improvement. Is there anything else I could try or anything that I have overlooked?
Best regards and thanks in advance!
