PBS Executive IV

In 1985 Portable Business Systems Limited in 1985 took a Sinclair Spectrum+ and incorporated it into a large briefcase along with a ZX Interface 1, ZX Microdrive, power supplies and an Alphacom 32 printer.

Our unit is type: 171285 with a serial number of 1358.

The system was developed for the financial industry and allowed sales representatives to take the system to a clients house and present a visual demonstration via the clients television.

The printer allowed them to leave financial information with the client, this was an early portable solution to take the office out on the road.

Manufacturer: Portable Business Systems Ltd
Date: 1985
