Mac Classic II 用 FPU カードです。 Classic IIではアップグレードカードがかなり少ないですが、FPUカードは唯一・・・となります。このカードには、FPU をオーバークロック出来る機能があります。注意点としてはFPU を徐々にオーバークロックすると、CPU のパフォーマンスが反比例して低下することがベンチスコアから見て取れます。したがって、最適なバランスを見つけるのが重要です。FPU は 40MHz までオーバークロックできることが確認されていますが、個人的な経験に基づくと、25MHz 前後にすると CPU のパフォーマンスはかろうじて保持できます。*画像6では40MHzのオシレーターが取り付けてありますが、CPUパフォーマンスが2%ほど悪くなり、あまりおすすめではありません。もともと68030世代の中ではさほど高速ではないMacですので。

FPU オーバークロック方法

1. 販売時にあらかじめはんだ付けされている J3 のはんだパッドのはんだを外します。約 80W 以上のはんだごてを使用すると、2 つのパッドが効果的に分離されます。これにより、J2 オーバークロック セレクター ジャンパー ピンが有効になります。*5番目の写真

2. J2 に 1x3 ジャンパー ピンを取り付けます。ジャンパー ピンを移動することで、カード上の CPU クロックまたは水晶発振器の使用を選択できます。*5番目の画像
裏面のシルクスクリーンに表示されているように、SYS はシステム クロック (CPU クロックと同じ)、OSC はカード上の水晶発振器です。

3. 水晶発振器を X1 の位置に取り付けます。推奨周波数範囲は約 33MHz です。5V 駆動の発振器を使用します。8 ピンと 14 ピンの両方のサイズを使用できます。ピン 1 のドットがありますので、方向を正しく合わせてください。物理的な干渉はないので、高さが増すのが気にならなければピン・ソケットを使用できます。*6番目の画像

Proxy bidding and purchasing services are becoming increasingly convenient. However, overseas shopping carries certain risks and issues. To reduce these risks and enhance shopping safety, please be sure to read the following information:

1. International Shipping

   Air Freight: If the item status is not confirmed within two days after the arrival notice, any customer complaints cannot be addressed with the seller.

2. After Receiving the Product

Please confirm and inspect the product as soon as possible to ensure that the product specifications, quantity, accessories, and description are correct

If, unfortunately, there are any issues, you can refer to the following examples on how to report related product problems:
1. Example of missing product information
2. Example of product not matching provided information
3. Example of damaged product information

Important Notes: 1. If the seller is unwilling to ship overseas or is unaware that the product will be shipped overseas, the international shipping cost for returns or exchanges will need to be borne by the member. You may refer to the EMS e-Express fee inquiry from the post office. If it involves alcoholic beverages or items that affect flight safety, the post office cannot be used for shipment, and only DHL can be used to ship back to Japan.
2. During the product complaint handling period, please retain the complete outer packaging of the product (including the shipping label information), and refrain from attempting any repairs or altering the original condition. Any modifications may result in the inability to process the case.

3. After Inspecting the Product

After receiving and inspecting the item, if you have any questions, it is recommended to contact Letao within 2 hours. Here are some reminders:

1. Please do not unpack, use or repair the received item yourself, and be sure to keep the original packaging to facilitate subsequent handling of related matters, so as to avoid changes to the item that may cause the seller to be unwilling to process.

2. You can call customer service, and the customer service will leave a message for you as below. Please provide the following information:
"Hello, we will first help you establish a complaint case for Product ID: _______ .But we need you to 2-3 clear photos of the product issue, including photos of the product problem, product packaging, shipping details slip, and outer box. Send them to service@letao.my and inform us of your desired resolution (failing to provide this may result in an inability to process subsequent matters). After sending the email, notify us in the customer service message. We will confirm with the seller as soon as possible. and if there are any related questions, we will contact you through the customer service message. Thank you for your cooperation."

Please provide:
1. "Product ID"
2. Photo of the "Delivery Note" (if any)
3. Photos of the outer box (including inner and outer packaging)
4. Photos of the product (Please include relevant descriptions to help us confirm with the seller)

Important Notes:
1. Do not include foreign text or other products in the background of the image.
2. Please keep the complete product packaging (including the shipping label information), and refrain from repairing or altering the original condition on your own, as any changes may result in the case being unable to be processed.
3. Please provide the relevant information within 48 hours to avoid missing the golden hour for reflection and causing situations that cannot be handled.
4. Due to 99% of Japanese sellers being unwilling or unaware of shipping goods overseas, if a seller is willing to handle the issue, the goods must be sent back to Japan, and the international shipping costs incurred must be borne by the member. Letao will use postal EMS international express to send the goods back to Japan.
5. As the goods are purchased from overseas, it may take approximately one to two weeks to complete the relevant processing procedures when issues arise with the goods. Please be reminded that you can inquire about the approximate cost through the EMS service at the post office.

4. FAQ

1. Issue of Authenticity: If antique or branded goods are found to be counterfeit upon receipt, clear photos showing the differences between the genuine product and the imitation must be provided as evidence. If unable to provide relevant proof, assistance can be sought to find a third-party reputable organization for a premium authentication service .
2. Leaking Iron Teapot: If an antique iron teapot is leaking, please take clear photos of the leaking area and provide them.
3. Transport Damage: If the goods are damaged during international shipping (to the pickup point), you need to provide photos of the outer packaging of the parcel and clear photos of the damaged goods' outer packaging.
