info on buying & selling Sinclair computers
released in October 1984, was a stop-gap produced
to refresh the Spectrum at a time when the home
computer market as a whole was suffering a slowdown.
surveys showed that the Spectrum's peculiar rubber
keyboard was a serious turnoff for prospective
users. The Spectrum+ introduced no changes to
the basic Spectrum hardware but provided a "professional
keyboard" which had an uncanny resemblance
to that of the QL.
It was later adapted for the short-lived Spectrum
128. It was not a proper typewriter-style
keyboard as found on PCs, but instead used much
the same technology as the old-style Spectrum
48K (and the later Z88),
with keys - in this case made of injection-moulded
plastic - resting on top of a rubber membrane.
Many users did not find this wholly satisfactory
The machine sold
for £179.95 (compared to the cost of the
rubber-keyed 48K model at £129.95) or £50
for a do-it-yourself kit for the user to convert
a rubber-keyed version to a Spectrum+. Although
the machine sold adequately, the familiar Sinclair
quality control gremlins struck again - the keys
had an unfortunate tendency to fall off. Retailers
such as Boots reported a failure rate of up to
30%, compared with a more usual 5-6%.
