  • Wanted Dead zx81 ram pack issue1

    I am writing a "how to" on fixing zx81 ram packs but both the issue 1 ram packs i have have come to life after replacing the ribbon cable with connector strips.
    I need at least one with dead ram chips to replace them with 4164 chips!





    have a look at http://www.levosretrocomputerprojects.co.uk i have done the issue 3.
