No box. I'm not sure which is the A disk, so please boot up with MS-DOS in the A drive first, then insert one of the disks into the A drive and the other into the B drive to check if they boot. I've added image 8, please refer to it. Regarding this product, I'm not entirely confident, so I would appreciate it if only customers who understand and agree to this purchase. Currently, the 5-inch PC9801 I own doesn't make the "pikon" sound when powered on, so I can't confirm if it boots. Expect a story like a salesman's "DOON!" Image 9: DOON! Boot-up not confirmed. I am a smoker. Please refrain from purchasing if you are sensitive. Price negotiation is possible, feel free to ask. No returns or claims, please. #maybe2525MiscellaneousGoods PC 98 PC9801 5-inch Apple pie
