This is an old book from over 30 years ago, so there may be damage, deterioration, yellowing, stains, pages that are torn or folded, and odors. I haven't checked every page, so I may have missed something. ⭕️ I think it's okay to read for now. ⚠️ No supplements included. Everything is in the photos. For those who understand used books, thank you. NEC PC-9801 PC-9821 PC-8801 PC-8001 PC-98 games FM sound source MS-DOS PC8801 X6800 FM7 PC9801 MSX X1
