In 1989 Psion introduced the '''four-line''' machines. The '''LZ''' has 32 KB of RAM and the '''LZ64''' 64 KB (32 KB plus two 16 KB banks). They look almost identical to the earlier machines apart from the slightly taller screen. All were multilingual, normally English plus two others.<ref name="models" /> | In 1989 Psion introduced the '''four-line''' machines.

Psion produced a series of point-of-sale and industrial machines. A POS model does not show a menu when switched on: it looks on the fitted packs for a procedure called '''BOOT''' and runs it. If it cannot find one it displays "PACK?" or "INSERT PACK?" briefly and switches off again. Many have non-standard keyboards.<ref name="models" /> | Psion produced a series of point-of-sale and industrial machines.
