I just remembered that once, log ago and far away (mid-1980s), I had an NEC PC-8201 (Radio Shack marketed it as the Tandy 100), quite possibly the first “laptop” computer.

I even stumbled across an active project site devoted to it.
I’d take it with me on walks, stop and sit with my back against an old tree and type away, expressing whatever was on my mind at that very moment. Not being one to discard things unnecessarily, I probably have those old (ancient?) missives archived on some floppy, firmy, tape, or CD/DVD somewhere. <grin> Hard to convince myself that even if I did find and resuscitate them, it would be significantly illuminating. But then again…………………..
