MicroDigital TK-83 – RF (PAL-M) to Composite NTSC
La modifica per l’uscita video composita del computer Microdigital TK-83 a differenza dello Sinclair ZX81 e’ piu’ semplice.
Non occorre installare il solito transistor con 1 o 2 resistenze / condensatore. Il transistor e’ gia’ installato sulla scheda madre del Microdigital TK-83, dunque basta prelevare il segnale video come viene descritto nella foto.
Vi ricordo che il segnale di uscita sara’ in standard NTSC per il Microdigital TK-83 prodotto in Brasile (PAL-M).
How, for the love of Osiris, HOW did you manage to get one of these? They’re impossible to find even here in Brazil!
Just an amend to the blog: PAL-M is the very same as NTSC, just the chroma signal is PAL. Since all ZX81 & clones produce only black and white image there is no conversion between standards.

Yes, you are absolutely right.
