than it is in a typing pool! I type for a
living, and I'd be quite happy to use the
Z88 keyboard - but this is a very
subjective judgement, and I'd advise you
to have a go before ordering a Z88,
especially if you're already an
experienced typist. Journalists that I've
spoken to come out about 50:50 for and
against the Z88 keyboard.
Z88 SYSTEM
It seems that - as usual for a Sinclair
machine - the Z88 has been launched long
before it is ready. The prototype was
running a neat Word Processor package, but
the spreadsheet, database and diary
software were nowhere to be seen. This
software will have to be uncommonly
reliable - there's not much point having
batteries that can preserve data for a
year if the software goes haywire and
scrambles things, or locks the machine up,
every few days.The Z88 will run BBC
BASIC - a dialect much-lauded by those who
know more about fashion than they do about
computer science. BBC BASIC is faster and
more expressive than ZX BASIC - but it's
less friendly. A version of BBC BASIC for
the Z80 processor has been available for
several years, so it should not take long
to get the core ofit running on the Z88.
It will be interesting to see how much
support we get for the paged memory and
LCD graphics. Will we be stuck with the
64K memory limit of other versions on this
machine which promises over 3 Megabytes of
'instantly-addressable memory'? The claims
about the memory capacity of the Z88
should be taken with a pinch of salt.
There are slots for three ROM or RAM
cartridges at the front of the machine,
and 32K and 128K cartridges are promised
to be available with the first machines in
April, with a 1 megabyte version coming
'soon'. That will be built around the
'wafer scale integration' ideas that have
been kicking around Sinclair's 'Metalab'
for several years - butthere's no sign yet
of the Ь6 million needed to get those
ideas into production.The only standard
interface is an RS-232 port, which allows
access to modems, serial printers, and
other computers - at least in theory.
RS-232 interfacing is a black art at the
best of times, and Sinclair serial
interfaces have a reputation for
idiosycracy.
PROVISIONAL VERDICT
I enjoyed reading the Z88 brochure, and
-as usual - I wanted to order one as soon
asI'd finished. The design seems full of
good ideas, but it's clearly not finished
yet. CAMBRIDGE COMPUTER are talking about
production levels of 10,000 machines a
month,but this is a pretty meaningless
figure, as it's the usual 'minimum order'
quantity for mass-production of
computers.I'll be pleased, but surprised,
if Sinclair can sell Z88's in respectable
numbers. EPSOM, NEC and TANDY have all
attacked the A4 portable computer market
and found slim pickings. The appeal of a
portable computer has been clear since
XEROX came up with the idea of the
Dynabook, long before the personal
computer industry existed. The Z88 is a
step in that direction, and will doubtless
appeal to some people, but the product
hardly lives up to the slogan,
'full-facility, no-compromise computing'
at the moment. It's especially sad that
Spectrum compatibility has been ruled out,
because that could have given the Z88 the
mass-market appeal that it presently
lacks. But Sinclair is still a man to
watch, and - rest assured -CRASH will keep
watching.
STOP PRESS...
Amstrad have announced a Spectrum Plus
Three. This will have one built-in disk
drive in place of the Plus Two's cassette,
and an operating system written by
Locomotive Software,the firm's tame
programming house. At the time of writing
(early March) there's been no sight of a
finished product although that hasn't
prevented less reputable magazines than
CRASH from getting their crayons out. The
word is that boss Alan Sugar has given the
development team until the end of March to
sort out the design. We'll bring you all
the facts, and intelligent analysis as
soon as the new machine materialises.
