 ULTRA RARE Apple Serial NB Card - Apple Macintosh II NuBUS Hydra Cable Vintage:
$700.00

This listing is for one of Apple\'s rarest NuBUS cards every made still sealed in box! I even have one of the very rare and specialized cables to go with this card, albeit the cable is used.
The card is the \"Apple Serial NB Card\" and was neither cheap or a common card for most users making it very niche and rare. The 12\" card was originally designed for use in the Mac II for advanced communications systems. It even has its own 68000 processor onboard to take load of the main CPU in the Mac. The cable included, sometimes called a Hydra cable, was made specifically for the card and connects to the db-62 on the card to supply four db-25 connectors.
The card is still sealed in box and new but the clear wrapping shows signs of age but is overall in excellent condition. There are four holes in the plastic wrap from production where the cardboard box under those spots has yellowed. Two in front and two in back, see photos. The cable is used and shows signs of age but pins looks great.
Below is from the Apple press release, but I recommend searching online for more info:The Apple Serial NB card is an intelligent NuBus card that uses Apple\'s Macintosh Coprocessor Platform (MCP) architecture. It provides additional communications and processing capabilities to a Macintosh computer.The card includes a Motorola 68000 processor operating at 10 megahertz and 512 kilobytes of random access memory (RAM), which is expandable to 1MB. Software for the MCP consists of MCP/OS, Apple IPC, and support software. MCP/OS and Apple IPC supports a multitasking distributed operating environment for communications and other real-time services on the same card.The card uses two Zilog SCC chips to support a total of four serial ports. A 62-pin connector on the back of the card breaks the electrical signalling into the respective ports. These ports can be configured to operate as four RS-232-C ports, or as two higher speed ports (such as V.35) and two RS-232-C ports. The RS-232-C ports can operate at speeds up to 19.2 kilobits per second (Kbps). The higher speed ports are DMA-backed and can operate at speeds up to 64 Kbps. Cabling for this card comes in two flavors: the Hydra cable, which provides four RS-232-C connectors (M0128LL/A), and the V.35 cable (M0127LL/A), which
provides one V.35 port and one RS-232-C port.
