Good for you. Looking on eBay these prices seem reasonable, given I don't have a time machine.
So about the Panasonic, it looks like it could be upgraded with more RAM. Any other issues? It has RGB out.
I've seen s Panasonic FS-A1F MSX2 for sale for 20,000 yen. Is it a good buy?
I'm expecting to replace the drive, re-cap it etc.
I have never owned an MSX but I do speak Japanese and can read it at basic level (hira/katakana and some kanji).
