Back in the 1980s, there were quite a lot of 8-bit home computers to choose from and, while it might seem somewhat surprising to us RISC OS using Acorn fans, some people actually chose other machines than Acorn’s BBC Microcomputer.
And enjoyed using them.
Strange, I know.
One of the most popular of these was the Sinclair ZX Spectrum which, it its original form, was a tiny little rubber keyed beast sporting either 16kB or 48kB of RAM. It sported a screen resolution of 256 x 192 pixels, or 32 x 24 characters, and actually had a slightly better palette than the Beeb; you could choose any of seven colours at one of two shades (normal and bright), plus black – though, for graphics, the colour attributes could only be set for an 8 x 8 pixel block, rather than for each pixel.
Users of modern machines have been able to put themselves in a position to try and understand the mindset of those who liked such quirky little machines by way of emulators, and one such emulator is called Fuse, the Free Unix Spectrum Emulator. Originally developed for Unix, it has also been ported to Mac OS X, Windows, Amiga OS, MorphOS, and even the Nintendo Wii – and now, thanks to the efforts of Chris Gransden, it has also been ported to RISC OS.
The RISC OS port, which can be downloaded from riscos.info, runs at 100% emulation speed on a minimum of a StrongARM RISC PC, and features:
- Accurate 16K, 48K (including the NTSC variant), 128K, +2, +2A and +3 emulation.
- Working +3e, SE, TC2048, TC2068, TS2068, Pentagon 128, Pentagon “512”
- (Pentagon 128 modified for extra memory), Pentagon 1024 and Scorpion ZS 256 emulation.
- Support for loading from .tzx files, including accelerated loading.
- Kempston joystick emulation.
- Emulation of the various printers you could attach to the Spectrum.
- Support for the RZX input recording file format, including ‘competition mode’.
- Emulation of the DivIDE, Interface I, +D, Beta 128, Opus Discovery, Kempston mouse,
- Fuller audio box, Spectrum +3e, ZXATASP and ZXCF interfaces.
