This is a recent acquisition of a neat historic laptop. It's a Zenith TurbosPORT 386 that is reportedly one of the first laptop computers that has rechargeable batteries. Previous to this model, all portable computers would have been called "luggables" since they needed to be plugged in. This laptop has a "paper white" LCD display that I'd love to see but sadly, the power supply isn't working and there is very little information on the Internet about this model. It was quite expensive at the time being Zenith's top-of-the-line model.

The keyboard on this laptop is interesting because I don't believe I've seen a black PCB design before this. It looks quite striking with these Alps low profile common mount key switches. These are the white slider version that are obviously PCB mounted. The keyboard mechanism was made by Alps in Japan but you can see the board has a Zenith specific keyboard controller. This keyboard also has a switch but I'm not sure what that is for. It may switch from XT to AT but why would it be possible if this keyboard id specifically for this model? Unfortunately, there is no manual online so I will never know.

Anyway, here are some pics. Enjoy.

What power supply came with it? Should be an external AC adapter of some sort?

It's a bit of an odd power supply. Here are the specs in pics in case you have one (never thought to ask)? (note: normal PC plug goes into the bottom of power supply in the first pic)

That's a very interesting-looking laptop. The key caps look particularly nice, dye-subbed PBT from the looks of it.

The layout appears to be identical to that on the Zenith SupersPORT, which looks like the only Zenith laptop currently documented on the DT wiki. But that seems to have pad-printed legends on doubleshot key caps and Alps Integrated Dome.

I replace caps on a regular basis As the Reddit poster stated, all looks well in my power supply too but I know there is no output (even though I'm not sure what pins provide what output). I think I will have to start replacing caps. THanks for the post. I had found those pictures but not the Reddit comments.

Great rare Alps common mount low profile switch.
Is that contact legs can fit on the alps SKCM/SKCL PCB mount?
