I was using a variable supply but just bought a 7.5v switching supply in "wall adapter" form factor. It comes with the correct connector for the Micro-KIM and works great. It is rated up to 1.6A so has more than enough capacity to power the Micro-KIM. Purchased from Mouser as 418-TR1507 fo...

The Micro-KIM acts like a modem. That means a straight through cable from your Linux machine should work. Set comm rate to 1200 bps and no handshaking to start with. If you can introduce character and line delays do so as suggested in the Micro-KIM manual. With jumper in place do a Micro-KIM reset a...

With the 1000 ohm resistor and the existing 220 ohm resistor in series with the Q7 output there should be no ill effects on Q7. The -9v through the 1000 ohm resistor does limit the positive swing to probably +3v or so. I did not put the scope on it to check that but +3v would still meet RS232 spec a...

Vince,

What is latest estimate for availability of new run of 32K RAM Cards?

My Micro-KIM is working great but the RS-232 interface (transmit only) does not work with all machines. I found that for some I needed to bias the static voltage on pin 2 to a true negative value. The simplest approach I had success with was just to use a 9v battery with the positive terminal connec...
