Zenith 486 Laptop power plug help

S

Salvatore

I need to know the pin polarity for this unit so I can put some power to
it and see if it works. No problem getting a power supply if it works OK.

Owner is a friend and would like to replace their 386 laptop with this
powerhouse. I am astonished that the 386 works at all, and the mono LCD
only good for text. This was given to them and is of unknown worth.

I do not have a clue to this barrel connector with rectangular center
occupied by 2 rectangular side by side pins (nearly square)

Model ZNote 433Lnc+

Power supply connector looks like

I could apply the required 15.5V and do the smoke test with a 50% chance
of success, or even 100% if the device is protected from polarity
reversals (battery out). Please advise

Any experience with one of these old tanks anyone??

Happy New Year!!
