    It is. Unfortunately it can be also bad data line. Check PCB, as I remember 3b has soldered DRAM. Otherwise you could just put 4164 chip in socket.

  • Made in KoreaJust a couple of questions. Were there many 48k Speccys made in Korea and when were they made?

    48K rubber from Samsung is issue 2. Not sure if issue 3/3b were still made in Korea.
    BTW. As I remember Apina in Poland was assembling ZX 48K+ using 4s boards.

    As you say, disturbing. The Modulators are showing signs of rust!
    As for the wherabouts of the ULAs....? They can be the most valuable bit.
    Mostly issues 3B, 4B and a 3rd issue which I can't see.
