    Default Yellow board ZX Spectrum 48k issue 4A.

    Hello all.

    I sale my ZX Spectrum 48K with the rare *yellow* 4A motherboard, in working order.

    During the production period of Sinclair ZX Spectrum micro computers, the motherboard design evolved in order to make improvements to the circuit. The revision 4A motherboard is widely regarded as the most reliable motherboard designs of all Spectrum 16K/48K models.
    During Issue 4A production run, for a limited time only, the printed circuits were manufactured using synthetic resin bonded paper (SRBP) material, giving it its distinctive yellow colour, as opposed to dark green colour of a regular ZX Spectrum mainboard.
    The uniqueness of yellow motherboards makes this variation one of the most sought by collectors.


    I sale the unit only.



    • NO PSU included.
    • NO cables included.


    This unit have composite mode with capacitor. No other works made in the board.
    New quality keyboard membrane has fitted.

    I am asking 120 +Shipping (Paypal family & friends) - Worldwide registered Shipping.
