It was very common in these older PCs for the RAM chips to "walk" out of their sockets. It may just be that they need to be reseated with firm thumb pressure on each chip.

Difficult to say. It's certainly a possibility with something that old. A little Googling has revealed that the RAM chips in the Compaq Portable 1 were soldered in, not socketed. That makes it a whole lot more likely that it is a failed chip, and a whole lot more difficult to fix. Unless you are good with a soldering iron I'd be inclined to give it a miss.

"Unless you are good with a soldering iron I'd be inclined to give it a miss."

Even if you are good with a soldering iron, I'd be inclined to pass. Disassembling a Portable I isn't for the faint-of-heart. Compaq packed a lot of hardware into a small space and removing/replacing cables/cards/drives/MoBo's in one is a real PITA.

A soldering iron is way too big. Maybe a soldering pencil. Probably best to clip the pins and remove the pin individually. Need wick and a sucker and a steady hand. If you are lucky only one chip.
To get the motherboard out mean disassembling almost everything.
