Thanks to some generous sponsoring by Asklia I was able to decap the MCS6530-004 aka TIM early May 2021.
ttlworks once again joined and took over the majority of documentation work which I'm proud to reproduce here.*
Enjoy... and stay tuned for the next chip(s)!
* As in previous dissections I just copy&paste the text written by Dieter/ttlworks... which should not confuse
anyone if he speaks of himself or cites some reminiscenses!
