PC10466 Series ARCNET® Network Interface Modules for PC/104 computers Description The PC10466 series of ARCNET network interface modules (NIMs) links PC/104 compatible computers with the ARCNET local area network. ARCNET is classified as a token-bus LAN operating at 2.5 Mbps while supporting 255 nodes. Interfacing ARCNET to a host computer usually requires a NIM which plugs into the host computer’s bus. The PC10466 incorporates the 16-bit COM90C66 ARCNET controller Benefits chip with enhanced features over the earlier generation ARCNET chips. New features include command chaining and sequential I/O • COM90C66 16-bit controller mapping of the internal RAM buffer. There is usually no • Interfaces ARCNET with PC/104 bus requirement for wait-state arbitration. The PC10466 is backward computers compatible with earlier generation 90C26 and 90C65 8-bit ARCNET • Zero wait-state arbitration typical controllers and will operate as a replacement. However, to utilize • Deterministic high speed 2.5 Mbps ARCNET the expanded features of the COM90C66, an enhanced software token-passing local area driver is required. network (LAN) • COM90C26/90C65 software compliant Each PC10466 module has two LEDs on the board. The green LED • Command chaining for enhanced indicates that the module is transmitting data on the network and performance the yellow LED indicates bus access to the module. The PC10466 • Supports either memory mapped or I/O also has an external DIP switch so that node addresses can be mapped RAM buffer easily reassigned without removing the module. • Node address switch selects one of 255 possible station addresses There are five versions of the PC10466 ARCNET NIM. The PC10466- • Supports coaxial, fiber optic and CXS supports coaxial star configurations requiring external active or twisted-pair cabling passive hubs. The PC10466-CXB supports coaxial bus configurations • Boot ROM socket for diskless workstations usually requiring no hubs.

TERRIFIC RESOURCE
This company has been a terrific help to us (I work for Trican Well Service) in sourcing the Micron Ram Memory we needed for our Siemens computers. Great service! And great pricing! I know when the product is shipping and when it will arrive, all the way through the ordering process.

GO TO SOURCE
When I can't find an obsolete part, I first call GID and they'll come up with my parts every time. Great customer service and follow up as well. Scott emails me from time to time to touch base and see if we're having trouble finding something.....which is often with our 25 yr old equipment.
