Got another laptop. It's got a couple issues unfortunately (I likely have to find a new LCD for it to get rid of that blue line, and the battery is obviously dead) but it's still fun and has a Yamaha OPL3 synth chip inside.
For $10 I'm not too disappointed honestly. I have the floppy drive bay and this backpack CD drive for it.
Someone's asking $100 for the only LCD that's currently on ebay unfortunately. And all the results on aliexpress for the LCD panel number (LTM09C031A) show widescreen panels which this obviously is not.
I have a JP friend or two on IRC.
Also the manga I scanlated had a running joke about the "old maid" type. What you describe seems accurate but at the same time the author portrays her as waiting for a literal prince on a white horse to come to her.
