Apple Extended Keyboard for Macintosh SE II ADB Desktop Bus Vintage

Selling the pictured vintage beige Apple Extended Keyboard I, model number M0115. Fully tested and working. An ADB port is required for use. The keyboard was manufactured from 1988 to 1991 for the Macintosh SE, Macintosh II and Quadra products. The ADB cable is included.
The keyboard has two ADB ports: one going to the Mac, the other for a mouse (not included). Some Apple products of the era have brittle plastic and experienced light to moderate fading yellow from ambient lighting over time. This is not a museum piece; do not expect it to be in pristine condition.
All keys and ports are tested and work. Nothing feels loose, and nothing rattles inside.
The fine print:

Placing a bid in an auction or a purchase for an item signifies your understanding amd acceptance of these terms, in addition to those in the Pricetronic user agreement.

Payment must be received within 5 days of making the purchase or the auction closing. If you are unable to pay, do not bid.

Shipping, insurance, and handling is specified by cost listed in the posting, or will be determined at the end of the auction, and is subject to value, weight and destination.

Item will be prepared for departure as soon as possible after payment is complete. Shipment is unavailable on weekends or U.S. holidays. Items are packed sufficiently to protect the item from reasonable handling (it's impossible to protect against a drop from orbit, say).

The description and photos describe the item as accurately as possible. If there are defects I know about, I will list them (e.g. if something is loose or rattles and shouldn't, I will say so in the post). Do not assume something works in a certain imagined way, or that a part is included if it is not shown or described. Search for technical specifications from authoritative sources on the web if you need to. Don't assume I know all.

Email questions as early as possible before bidding or purchasing. Emailing within the last few hours of the auction end does not guarantee a response in time.

Items are sold "as is" and without warranty. There are no refunds or exchanges unless otherwise noted. Costs of shipping, insurance, and handling are nonrefundable.

Auctions that are not completed will become null and void, with possibilities for the item to be relisted. Bidders who do not pay, others who sabotage the seller or contradict these terms, and sellers who do not perform will be registered on a blocked bidder list, and they will remain there.

Any communication or other activity including inappropriate remarks or behavior or defamatory references will be reported and the offender blocked from communicating or purchasing.

Bidders must be legally eligible to participate in the auction/purchase. Seller reserves the right to suspend suspicious bids. Do not ask seller to cancel bids placed in error.

Non-paying bidders will be reported and blocked from future auctions/purchases. Decisions rendered by the seller are considered ultimately as final, in accordance with standard Pricetronic procedures and policies.

Copyright Protection. I grant anyone the right to use the photos I post -- they're just product photos, for crying out loud, not fine art. Just remember, if you use my photos in your auctions, your buyers may notice that what they receive doesn't exactly match what they saw in your auctions. Same with this text. Go ahead, I didn't put too much time or literary merit into this.
