In this video a test is performed by builtin rom of the Dandanator on a Sinclair ZX Spectrum that has issues. Test indicates that chip 5 of lower ram is broken. Lower ram is used by video too, this is why there are strange artifacts on the video and the spectrum does not show the classic white screen at startup. Further informations on this test rom on Github page of his author, Brendan Alford: [ Ссылка ]


If you've have old electronic stuff and you want to support my studies and experiments, please consider to donate me something: I'm always in search of old computers and calculators (such as commodore64, zx spectrum and all stuff like this).
