RD PORTS FOR SPECTRUM

RD Labs has made most of its range of input/output ports Spectrum-compatible. So the scientific or educational user has a wide range of test equipment at his disposal. Devices include digital I/O ports, analogue inputs to one port and a real-time clock

The clock is battery-backed and has a calendar, as well as the time protected for up to four months without power.

All the units are memory-mapped and Spectrum users require an adaptor as well as the basic motherboard and ports. The prices range from £33.93 for the digital port to £51.24 for the real-time clock/calendar. The Spectrum adaptor costs £9.50 extra.

There is a 10 percent discount for cash with order but you must add £3 postage to the VAT-included price.

RDLabs also does mainframe units for industrial users; price on application to RD Labs, 5 Kennedy Road, Dane End, Ware, Herts SG12 0LU. Tel: 0920-84380.
