Hi again. I am new to M24. I am restoring a set of several M24 PCBs, and when powering the M24 it signals no error for the absence of keyboard and boots from the floppy drive. Is that normal? There must be some problem with the motherboard or misconfiguration? When I attach Valerio's freshly built keyboard converter it does not make any change, the computer behaves identically like with no keyboard/converter connected.
