Design
According to an article published in Sinclair User magazine, Loki was to have a 7 MHz Z80H CPU, a minimum of 128 KiB of RAM and two custom chips providing much enhanced video and audio capabilities compared to the ZX Spectrum, but with a compatibility mode. The video chip, referred to as the "Rasterop" chip, would have blitter-type functionality and three different modes: 512×256 pixels with 16 colours, 256×212 with 256 colours, or 256×212 with 64 colours and two bits per pixel used for "blitter objects". Comprehensive peripheral support was also claimed, including MIDI, lightpen, joystick and floppy disk. A version of the SuperBASIC language from the Sinclair QL was to be provided in place of the old ZX Spectrum BASIC and support for the CP/M operating system was also intended. On top of this, the computer would cost as little as ₤200.
Another Spectrum magazine, Crash, poured scorn on the report in Sinclair User, dismissing the design as a "dreamware" in the opinion of an ex-Sinclair designer they consulted, analysing the implied components and costs, and adding, "It may be fun to dream about Loki, but the fact is that it won't appear, and nor will anything like it." This was the rationale, according to Crash Technical Editor Simon Goodwin:
Being blessed with lots of headed typing paper and very little money, the Thinkers at Sinclair were invited to make a big list of trendy computer features. That list, embellished with a few charts and tables but a noticeable lack of circuit diagrams and real detail, finally escaped into the hands of the computer press. Despite six years of agonising experience of the difference between Sinclair specifications and reality they swallowed it whole. Technical know-how has never been a strong point in magazines that still—indeed, the same month—print Commodore 64 screen shots in their Spectrum software preview section. —Read more about this topic: Loki (computer)
Famous quotes containing the word design:
“Nowadays the host does not admit you to his hearth, but has got the mason to build one for yourself somewhere in his alley, and hospitality is the art of keeping you at the greatest distance. There is as much secrecy about the cooking as if he had a design to poison you.”
—Henry David Thoreau (1817–1862)
“Westerners inherit
A design for living
Deeper into matter—
Not without due patter
Of a great misgiving.”
—Robert Frost (1874–1963)
“Humility is often only the putting on of a submissiveness by which men hope to bring other people to submit to them; it is a more calculated sort of pride, which debases itself with a design of being exalted; and though this vice transform itself into a thousand several shapes, yet the disguise is never more effectual nor more capable of deceiving the world than when concealed under a form of humility.”
—François, Duc De La Rochefoucauld (1613–1680)
