MDS Qantel Inc, Hayward, California has added a desk-top processor to its proprietary business computer line and replaced its previous entry-level System 45 machine with the 45xp. The System 43 supports up to 15 users and is the new entry model as well as an upgrade for users of Qantel’s AT-based multi-user System 15. It runs under Qantel’s BEST/AOS operating system and is about three times faster than the 15. It takes disk drives of up to 160Mb and takes up to 1Mb main memory, the system coming in a 22 by 14.7 by 6.4 box that can be either horizontal or vertical. It has a quarter inch tape streamer, one vacant slot for communications, printer or terminal controller. With 45Mb disk and one terminal it is $14,740. The System 45xp is identical to the old System 45, except that it uses the more powerful processor of the System 43.
