As I have to move soon, things are on hold now. :-/

The CMOS one is definitely the better one.

Overall you are probably right - but looking into nostalgia NMOS is the choice, and also in seeking some challenge w/ undocumented instructions.

The CMOS replaced the illegal NMOS op codes with more useful added instructions and addressing modes, and still leaves some illegal op codes which can be exploited for fast (single-cycle) I/O. But true, if you want to run legacy software that was written for the early NMOS machines using the NMOS illegal op codes, you'll have to use NMOS. I'm rounding up all the NMOS-CMOS differences now to put in a web page. There are lots, both hardware and software.

Ok... soldering gun is fixed.

Today 2xCIA 6526 and 1xVIC 8565 arrived. I got them cheap on ebay, but have no clue yet if the are operational at all.

Soldering gun? Isn't that a bit brutal for working with chips? :?:

:mrgreen: Non-native speaker (or writer) mixing up things... does "soldering iron" sound better and less brutal?

Yes. :lol: I see "soldering gun" and I visualize the 125 watt one that I use for machinery repair purposes. If I were to use it to solder chips to a PCB it would be akin to swatting flies with a sledge hammer. :lol:

*yuck*

Moving from one place to another is poisonous for such things....

Just to let you know, I had to move last year, and will have to move soon again. So my SBC-project is on hold :-/
