  • Spectrum 48k boots but small black dots start appearingAnyone any ideas where I should look first?

    check for shorts around all the ram chips and on the edge connector.

    I had a 48k that gave all sorts of weird freezes and garbage booting up which turned out to be a tiny flake of solder shorting between two pads on the edge connector.

    im trying to repair a zx spectrum but there is one thing im confused about..

    Hi Robin,

    The 48k has 2 memory banks. The 4116 chips are the lower memory and make up 16k. The upper memory is comprised of 8 broken 64k chips. They are broken (cheap back in the 80s) and can only see 32 of their 64k.

    The reason for wanting to test them is that I have 30+ 4116 chips and 200+ 4164 chips.
    They are of no use to me so if I can test them then I can offer them to users on here for repairs.

    That's what I do (sort of), but as I said, there's a risk of damaging the Spectrum (TR4) if I put a shorted 4116 chip.
