I have a picture!
I finally got hold of a DVI to VGA adapter and could try the VGA input on my Dell monitor.
Thanks turrican9!
The picture is off center quite a bit but I hope to fix this with some tweaking using the AGA MK2 config tool (just need to transfer/install the config tool on my A1200).
My goal is to use the HDMI input of my Aliemware monitor. Is there a "disable analog and enable digial output" option I have to enable in the config tool to make it work as intended?
What still worries me is the temperature. After a while the three voltage regulators on the AGA MK2cr gets too hot to keep my finger on. I have these marked A, B and C in the picture below.
I borrowed a FLIR i3 thermal camera from work to do some measurements.
The A1200 case and keyboard are flipped open and I measured the temperature of pos A, B and C every 5min over the course of one hour.
Room temperature was around 24 C and no AC, fans, etc. were used.
After 25min the temperatures seemed to have stabilized around 67 C for each of the "hot spots" and did not increase any more.
These are the final temperatures of the AGA MK2cr after 60min:
Pos A
Pos B
Pos C
Overview (currently measuring pos B)
The temperatures would likely be higher with the A1200 case closed. I am currently not using any active cooling in the A1200, would this be required for the AGA MK2cr and ACA1221EC combo? (The ACA1221EC stayed lukewarm at around 45C during the open case testing).
Jens, I have a "FLUKE 115 true rms multimeter" and can do voltage measurements if you direct me to where. It is not a calibrated multimeter but I can borrow a more advanced model from work if it is inadequate?
