Products and brands

HH introduced an electronic piano, the P73, in 1981. The P73 offered five piano and clavichord voices, and was controlled by a microprocessor. The P73 was used by keyboardist Duncan Mackay.

In late 1983, HH launched the Tiger microcomputer, the design of which had been acquired from Tangerine Computer Systems, featuring a Zilog Z80 processor equipped with 64 KB of RAM for running the CP/M operating system, a Motorola 6809 processor with 2 KB of RAM for input/output control, and a NEC 7220 video controller with 96 KB of RAM supporting 80-column, 40-column and videotex-style text modes along with an 8-colour 512 x 512 graphics mode. The machine was equipped with a modem for access to Prestel and other online services. As was common with microcomputers of the era, the core functionality was situated in the keyboard unit, with a separate unit combining a 14-inch colour display and dual floppy disk drives. The base system was priced at £2,795.
