Yarc ProTran PC-AT Coprocessor System

General Description

The ProTran brings to the transputer VAR, OEM or end user a reliable platform for shipping and developing applications software.  YARC has used its coprocessor interface expertise to produce a board that is not only compatible with all B004 software, but is also able to achieve the full I/O potential of the transputer’s links onto the AT bus (over 1 megabyte per second, single link).

Each ProTran board can be equipped with 1 to 4 transputers.  The root transputer can be configured with 1, 2, 4, 8, or 16 megabytes of DRAM.  Each of the other three can be configured with 1, 2, 4, or 8 megabytes.  All configurations give zero wait state performance.  All links, event inputs and subsystem control signals are fed to a proprietary pin-field array.  A daughter board, customized to your application, is plugged over the pin-field to correctly configure each board you ship.  There is no possibility of misconnected links or of cables loosening during shipment.  Board to board interconnects are performed with a 34 pin standard ribbon cable (same cable as a floppy disk drive).  Both outputs and inputs to the cable are fully buffered.  In prototype, wire wrap may be used to interconnect the transputers.
