So the parts I bought from a Wise 286 AT clone came in the mail today. Looks surprisingly clean. I was lucky to find together from the same seller the motherboard and the power supply, because it has weird connectors. More about that below.
Unfortunately my time today is limited, I managed to unpack and take some pictures, now I have to go on some family errands. Will do more tomorrow.
Motherboard and power supply. The PS is big, about twice the size of a modern ATX PS, and very heavy. A serious piece of iron.
Motherboard closeup. Unusual power connector, and a smaller 6-pin connector nearby where a secondary cable from the PS connects. 2 more connectors at the opposite end, ?for front panel? I don't know. There are 2 jumpers that I saw so far, one labeled W7 near the trimmer at the edge of the board not far from the EPROMs, and another one labeled W1 close to the 80287. Some solder pads near the EPROMs for more jumpers, not installed. Both W7 and W1 are closed. The EPROMs are 27128, one of the first orders of business will be to dump them and upload somewhere.
Power supply, label side. This is the only label on it. No power information, voltages, certifications etc. Interestingly enough it has a lithium battery warning - in the 1980s. I think I may have an idea why that is. Funnily enough, only the French warning sign explicitly calls it lithium battery.
Power supply, fan/switch/plug side.
At the opposite end the PS has a smaller box bolted on, from which a short cable emerges with a 6-pin connector that matches another one on the motherboard.
Same from another angle.
The two nonstandard connectors.
And the area of the motherboard where they plug.
I think there's a lithium battery in the small box, which probably acts as backup battery. I will see if I'm correct when I open it up. Interesting design decision, and one I haven't seen used in any other computer.
I will start by checking the PS and mapping its connector voltages. As well as the small connector.
I have contacted someone who has a functioning identical machine including disks and documentation. So far I have obtained some OS ans setup disks from him. Will post here if I get permission to do so.
I/O, I/O,
It's off to disk I go,
With a bit and a byte
And a read and a write,
I/O, I/O
