I'm using a straight cable, and everything seems to be soldered properly. The connection works properly when I use Kermit (a non gui hyperterminal) in linux with just a streight cable and no USB<->RS232 converter.

Yet somehow just using the USB<->RS232 cable doesn't work in windows.

Might want to check the output pin from the RIOT and or the 74LS06 to the LED segment if the lower left segment doesn't light up on all the segment displays. You might want to see if the segment physically lights up if its just one segment make sure you use a current limiting resistor if you try the...

Should some chips be warm?

I just started up my kim-1, and I noticed the 6502 and 6532 have some warmth to them after running for a while is that normal? I have to substitute the 7.5V supply with a 9V for the moment does that have a large effect?

Yes an IDE cable should work, however, some ide cables have one of the pins blocked with plastic, you can open it usually using a dremel with a really small drill bit and steady hand.

You know I just remembered, isn't the commodore PET a glorified KIM-1 with keyboard and video?

soldering the regulator

Its surface mount but that doesn't mean the task can be daunting. I posted a bad looking video of me doing it, my iron is having an issue with heat it seems, I guess that means I need to go and buy a new one or replace the heating element. http://youtube.com/watch?v=989gQKN_tz0 Steps in the process:...
