"This is a 100 x 160mm Eurocard which plugs into the
standard Acorn bus and interfaces to daisy-wheel printers via a ribbon cable.
Designed initially for the Ricoh RP1600 the card contains
two 16 bit 1/0 devices which are memory mapped into the Acorn system. Line
drivers and receivers connect via a 50 way ribbon cable header to the printer.
The Eurocard is intended to plug on to 6502/6809 Acorn systems via its 64 way
DIN connector but operation with any micro-computer system should be possible
including those with asynchronous busses e.g. 8080/Z80 based machines.
Acorn offer a software package for use with the card which
allows micro-spacing of the daisy-wheel for text justification. Full printer
handshaking and error condition sensing is provided.
