@Huxley Its an NCR CV-1053 , but was also sold under the Axion brand with the same model number.

How are the voltages. You can measure these either from the motherboard connector or from the floppy port. 5V from pin 6 and ground shell. If your 15.66Mhz is correct you can trace that down to the TSM ic. Thats where many of the main clocks are generated. You should be able to verify...

You seem to have no RAM in bank A, bank A has to be filled first. Memory detection is not automatic so you will have to set the resistor jumpers too to match what RAM you have. Unexpected RAM configurations can lead to very unusual behaviour.

Is your zuluscsi bus powered ? Try powering it separately. the 16" uses extended sense codes as opposed to the original sense pin system on the 13" , maybe its some weird interaction with 5V and pulldowns and diodes . Using a separate 5V could give a clue.

It's also a rev C , my rev A does not have it but the rev A has the Red battery holder.

I have that too.

what kind of issue do you see for Q10? red battery holders are certainly rarer than the black, I do have both

That looks like an 220V-240V international analog board, and looks like someone has been hacking it tbh. There is not supposed to be a resistor like that across the transformer/inductor like that on the 240V version. That resistor goes across the Live and Neutral through the fuse. There is...

Classic and Classic II are the same pinout. C-Video goes to video. Snd goes to an amp on the classic board , just ignore as SE goes directly to speaker just use rear speaker out to hear the beaps.

Correct answer is above, but if you are very desperate, you could make up a loom to connect a classic board to the SE chassis. They have very different pinouts and video is inverted.

Yea it's a point of sales 10" monitor on the IIc stand. With the rgb2hdmi you can set custom monitor timings so I also put it going with the Apple trinitron M1212

RGB2HDMI can also drive a VGA monitor This is a 640x480 VGA monitor driven by RGB2HDMI directly from the digital signals from the video port.

Hi ,I wrote 0V to denote supply ground as opposed to signal ground. The 12V, 0V, 5V 0V are on the supply side, the rest are signal ground.
