     Spectrum: from the layout - the product

              (As)

{} E. Marchenko, 1999


  Rumors that there is supposedly a developer - Clive Sinclair, 
who began to reach us about in 1985 from information received, 
it was clear that this person is seeking in its field to be 
"ahead of the rest." Naturally, I was caught, and I tried to 
get as much as possible information about it. And when I 
learned that Sir Clive has published a remarkable

gaming computer on the processor Z80, then,
of course, was reinforced by a strong desire
"Feel" this "miracle" with their own hands.

  Then one day, looking into the laboratory
Kozevicha I saw Dobush, bent
over maketnitsey. I have a keen eye:
recognizing on-board processor Z80, I immediately
realized what was happening, and jumped to the Jura:

  - This is it!

  He tried to keep silent and hide from
I pay "with his body."

  It goes without saying that there were strong
reasons not to disclose the first time information about this 
development. But from me something no apertures! In short, 
since the day I was in aware of all the translation work at the 
Spectrum our basic elements ...


  And when it came time to connect the Spectrum
to the TV, it was already on my part! And I proceeded to close 
the work. 

  Made by Yura computer is a lying on the table board with 
protruding from She leads and connectors. The keyboard was

to "mikrikah. Z80A CPU was still
was not - only Z80, and warmed it as ...
Well, you know.

  We had to bring it all in divine
form than I do. For the body I used a plastic rear cover of
Radio "Ocean", sold in
radio parts store. Further was the work, a scalpel, saws, files 
and dichloroethane. Material "blanks" enough

and on the top and the bottom cover of your computer - of 
course, by a cunning combination of its parts. Especially the 
original came out ventillyatsionnaya perforation. "Proprietary" 
label "SINCLAIR" I drank a jigsaw from the same case.


  Instead, the keys of arrows cursor control I built in the 
original building joystick on the ball, which I machined from 
hard rubber. Under the ball, I installed GDR'ovskie mikriki. It 
was very convenient: it was not necessary to grasp the handle, 
it was enough to put a finger in the notch at the ball and move 
them in the right direction. Another of the same joystick I did 
remote on the cord to provide a game together. In addition, in 
case I have further posted encoder colors and RF modulator to

that "slipped" and the sound that you can
was connected to domestic TV
through the antenna jack. To withstand the design in the same 
style, had specifically look black plastic connectors.


  I myself have made the two samples. One stayed with me and 
the other I gave Oleg Starostenko. The third is exactly the 
same computer made myself on my way one of our radiomontazhnik 
(he works on it until now far).


  Should zamemit that neither before nor afterwards, I never 
met such a constructive solutions. It seems that

his peers do not exist to this day. A
Actually, interesting happens: the computer made me "on his 
knee," looks true "brand" and other current "brand" - made 
"knee" novice "radiokohantsem. 

  Why are there long to paint! Turned
I do not have a computer, and a doll! Everyone
who saw it - initially in the bureau, and then
outside it - immediately lights up: "I want to make myself the 
same!" 

  While many reputable "offices"
Many were engaged in amateur-built
Computer Radio-86RK. Coming to them
guests, I immediately asked:

  - What have you got for the garbage?

  When he learned what had happened, they immediately rushed to 
our bureau. 

  Then someone took out of our our
The Spectrum in St. Petersburg. Who is - for the prescription 
of years I do not remember: Peter, we had very closely, and in 
the service mission there happened to be very

many.

  I remember buying a "blank" for the case of Spectrum, I asked 
the seller: 

  - You have a lot of these?

  - Yes, all the utility room crowded! - He replied.

  - After a week no one will remain -
I told him.

  He looked at me like I was crazy.

  Two weeks later, I deliberately went to the
the shop: no such cap on the radio there was no longer in sight.

  The genie was out of the bottle!

  Soon, throughout the Union became a big problem to get at 
least one RU5 ... 

  So that what was surprised when,
going to Kozevichu, I saw him, poor guy, sitting at his desk, 
his head in his hands and moaning: 

  - Oh, i nascho I їm then fortify themselves? Nascho
fortify themselves? ..
