Dataflex will release a Sirius expansion board plus a modem board for the IBM and Sirius in early April.

The expansion board will be kitted out with two serial ports, one parallel port, clock, battery backup, fitted memory of 128K upgradable to 384K and a price tag of £356.50.

The modem board, for use on the IBM and Sirius, will cost £172.50 and will enable you to dial into US and European networks as well as those in the UK.

David Low, director of Dataflex, said as long as everything goes according to plan, the board will be CCITT (European Communications Standard) and Bell Telephone compatible.

It will come with communications software, and by April may be accompanied by a Viewdata type package.
