アイ・オー・データ機器のPC-9800シリーズ用Cバス拡張ボードの一部に採用された通称「セカンドバスTYPE2」とメルコ(現バッファロー)が
昔発売していたCバス用メモリボードである「EMJシリーズ」

それぞれの物理的・回路的検証・解析から生まれた自作ハード「EMJ-8000SB」です

今ではわりと貴重なセカンドバス対応8MB Cバスメモリとして使用することができます

元々は自分使い用のハードとして開発したものですが、実装していない基板が余ったので組み立ててヤフオクに出品します

・Cバスの残りが1つしかないが、SCSIとメモリを同時増設したい用途(PC CLUB PC-286Cとか)
・286~386で専用メモリが手に入らず、640KBで我慢している、あるいは内蔵可能メモリ以上のメモリ容量を欲している用途
・V30~486で不揮発RAMディスクとして使用したい用途

使用方法は様々だと思います。また、286以上でプロテクトメモリとして使用する場合はドライバなどは不要ですが、RAMディスクとして
使用する場合は386以上の32bit CPUという条件は付きますが、現在でも対応ドライバがフリーソフトで公開されています(EDSK for DOS)

なお、286以下の機種でRAMディスクを使用する場合は別途MELWAREが必要です

設定方法も、元となるEMJシリーズのものをそのまま踏襲しているので、現在でもweb上に設定方法が検索可能で悩むことはありません

出品するのは、EMJ-8000SBサブボードと固定スペーサー(2個)のみです。写真に写っている
セカンドバス・ベースボードやPC-98本体、モニターなどは付属しませんのでご注意ください

-----------------------
多忙につき、なかなか製作する時間が確保できませんが少しづつ製作して出品していきます

不定期ではありますが素材となる部品どりボードとメモリチップが手に入る限り継続製作をしていくつもりです

ですが部品どり元が無くなった、または飽きたなどの理由により、突然継続出品が終了することもありますので、
ご入用の方はお早目の入札をお勧めします

-----------------------
当ハードは有志が開発した準同人ハードです。当然ながら開発・発売元であるアイ・オー・データ様やバッファロー様
は関係ありませんので、お問い合わせなどはご遠慮ください

また出品写真は使いまわしをしているため、メモリチップ形状や型番などの外観が写真と異なる場合が
ありますが、動作には問題ありませんので、その点はご了承ください
-----------------------
元々はジャンク部品を再生したものということで、本来ならジャンク扱いとしてサポートなどは致しませんが、
それらを組み合わせた動作確認済みの自作ハードとして、できる限りのサポートは致します。何か問題がありましたら
取引ナビかProject M.P.Sのサポートページからお問い合わせをお願いします

ただし問い合わせに失礼な対応をしてくる方のサポートは致しませんのでご了承ください

また新規の方、評価が著しく悪い方は入札をお断り、または削除することがあります
-----------------------
発送方法は「宅急便コンパクト」または「宅急便(60サイズ)」を予定しております


以上をご了承・納得いただけた方のみご入札をお願いします

International Shipping Methods
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.
