how to assemble a Spectrum yourself (a topic for beginners)
ZXNet echo conference «hardware.zx»
Hello, All
I went and looked...
I didn't find anything like that
I think this question will be interesting not only to me
The actual question is: how can a beginner assemble a Spectrum himself? preferably
modern like the Pentagon, Sprinter or ATM-Turbo (I don’t think I’ve messed anything up
:v2_conf3; );
so that there are few cases and it is easy to solder
with easily replaceable parts
to make the most of PC components (fortunately there are plenty of them now)
help a newbie and happiness will come to you ;)
Hello, D-M
Hmm, I liked the ReSpecT-2 version on the fan website
Is it difficult to implement? I just thought it was the easiest to install
Hello fan
yeah, I already noticed (though I’m a huge lamer and I can’t do it without assembly instructions
master)
here is another point of my technical specification
The Spectrum should be such that it can be assembled in stages
PS I ask all those who responded not to express themselves....
that is, expressed in a generally accessible language
Hello, D-M
DM> such that there are few cases and it is easy to solder
PENTAGON-1024 SL (pentagon.nedopc.com) ?
Hello jdigreze
I want something advanced and easy to assemble: v2_smoke;
But; we need to find a middle ground :v2_cry:
Hello, D-M
First, decide on the requirements, i.e. what are the benefits of this computer for you?
I personally like it. And from there you need to dance. The most advanced in this regard:
Sprinter and Turbo2+, but the first, as I understand it, has a rather confusing procedure
settings, the second one is easier to set up, but quite labor-intensive to assemble (details
you'll have to do a lot of soldering).
In general, and ideally, you need to buy assembled ones. ;) (even though I myself have this rule
I don’t adhere to it as a matter of principle, I try to assemble everything with my own hands)
Hello, The Exploited
no oscilloscope :v2_down;
A; what programmer do you need?
Hello, D-M
Judging by this, you won’t be able to assemble a single spec... you have a tester, an oscilloscope,
programmer? with a soldering iron on first name terms?
Hello, D-M
DM> no oscilloscope :v2_down;
DM>; and what programmer is needed?
Then it is better to think about the finished product. For self-assembly in addition to
soldering iron you need at least an oscilloscope, a programmer and a person who knows how to do everything
use this good and understand how the product should work, otherwise
An oscilloscope will not be useful.
Yes, here's another sad statistic. I have sold out of empty Pentagon 2.2 boards
about 10 pieces, so far no one has reported the successful completion of the assembly. I'm looking forward to it
who will be the first? But 3 people reported about the successful assembly of 1.4 boards,
and even then half a year after they purchased the boards.
I wonder what is the reason for such low activity? Either everyone is silent
partisans, or there is simply no time to do this and the empty board lies in
dusty box or something else?
Hello, D-M
DM> I want both advanced and easy to assemble :v2_smoke;
DM>; but we need to find a middle ground :v2_cry;
Rather; - available by components.
There is an elementary Leningrad1 - but you won’t find a fee for it.
Same as with many old clones.
Therefore, the most reasonable way is to order the assembled pent from King, or from NEDOPISI
ATM. Or at least a COMPLETE kit for assembly.
This way you will at least avoid the problem of flashing the ROM and searching for all
necessary components.
You can also, if you have a market for all sorts of junk in your city, try it there
search. I bought 2 pieces of Leningradov and
joysticks for 50 rubles... :v2_tong2:

Hello, Ivan
And so the topic was created in order to teach beginners lamers and dummies (to which
I am interested in) assembling an “atomic bomb”; I suggest taking a computer for examples
Pentagon-1024 (version 2.2) and use it to analyze all the examples (what’s the point?
replace, how it works, the order of assembly and testing, etc.)

Hello jdigreze
In my city, parts for the Pentagon 1024sl2.2 would cost an order of magnitude higher than
finished product.
Thanks to our TRD (television and radio parts store), sometimes you wait six months
some kind of connector, microcircuit.
Moreover, there are at least 10 pieces, so you either have to wait or look for others
solutions. If we need it urgently, we go to St. Petersburg, at the market or in Mikronik
Let's shop. Perhaps it’s the same in other cities, perhaps worse.
That’s why I ordered parts from us for the Pentagon, as soon as they arrive, I’ll order them
a clean SL 2.2 scarf (now the neighbor wanted such a computer).
The store management's explanation boiled down to the fact that if this product
if not only you were interested, but also the majority, he would appear in a matter of
days, and it’s very expensive for us to purchase from suppliers and negotiate with
new for the sake of a cheap part....
That's what they say here, and until competitors open another store (and it's in
in principle unnecessary) there will be no parts needed for an exclusive design.
Basically, you have to recalculate the circuits for those components that are in
availability, and the price of the finished product suffers from this and the quality suffers
"working scheme".
Hello, CHRV

To build a computer, yes, it is possible, but for work we need slightly different
components...

Almost collected. There are only 2 microcircuits left, a couple of relays and zener diodes (all in
I can’t get out of Moscow to get the remaining parts). Will visit you again soon
I’ll ask for an alter to flash. :-)
Hello jager

Hello, Mikka_A
I like the Pentagon-1024 based on reviews on this forum and just by appearance
HO!!!
there are a lot of small schemes
people!!!
We live in the twenty-first century, isn’t it possible to put everything into an FPGA or MK?
Hello, Mikka_A
got that sorted out
By the way, I also had installation practice at the institute: v2_finge;
question:; how and with what to flash the ROM?
and where can I see the diagram of a simple programmer?
Or will the same byteblaster still help?
Hello Vitron

IMHO it's easier to do it yourself...
because problems cannot be predicted.
I also had a lot of patience with spare parts and all the gadgets when I soldered the first one
GeneralSound a month ago.
And just take it and start working IMMEDIATELY, without any adjustments or settings.
So it's difficult to predict.
And start.
We take the scarf, insert the elements according to the diagram and solder them VERY CAREFULLY.
Then we connect the power supply and the TV, turn it on.....
And then it’s 50x50.
Or we see the inscription Sinclair Research Ltd 1982, rejoice and clap
clap your hands, or see what the hell, we get upset, turn on the oscilloscope and start
dig....
90 percent of boards that do not work the first time are installation errors, such
like, inverted mikruhi with the key in the wrong direction (less often), inverted diodes (more often
), mismatched resistor values (even more often, especially in the era of color markings
.... and the most common thing is banal SNOT on the board.
SO it is impossible to give any specific recommendations yet, except perhaps
two.
1. Carefully look at the diagram and assembly, arranging the elements.
2. Slowly and carefully solder.And after you do these two steps and the car doesn’t start, then
Let's think together and solve your problems.

Byteblaster for Alter firmware.
In addition to Altera, you have a simple flush. More precisely, in the original it is a flush with
ultraviolet erasure.
But I got rid of it and installed a microcircuit from Atmel 29Cxxx series.
The programmer can be made like this.

The author is burning! :v2_yahoo; :v2_yahoo:;
Well done!
I didn't have the patience to write this.
I would add from my experience.
Before soldering, flux the entire board.
Let it dry and then just stuff it.
I usually stuff it by placing the circuit board on the lid of a shoe box... so that
The elements were easy to insert.
I don’t bend the legs, but solder them from the side of the installation, then bite them and correct them
soldering on the installation side.
This is not a technical process, of course, but it is fast and effective. If the board is good
quality and with good metallization, elements are not oxidized, and temperature conditions
chosen correctly - the tin flows well, and there are no adjustments from the installation side
required.
Here.
If you're interested, ask...
I am, after all, a former professional installer. :v2_finge; 6; plowed for years

Hello, Mikka_A

naturally about AT29Cxxx

C; You don’t need to do anything with a flash drive.
Let's just say instead of 27s010 you put 29s010. and that's all.
why do you need an imported analogue?
Wait, it’s still possible to find VG93.
I bought 3 things just in case. As much as 27 rubles.
Hello, D-M

DM> 2. which bourgeois microcircuit should replace the VG93?
STC is not exactly 5 wires.
After all, there is one small device (AP5, buffer) I don’t think it’s difficult
repeat.
What kind of software are you talking about?
KR1818 VG93 agalog FDC1793
but I don't think you'll find it...
Hello, Mikka_A
But isn’t it sewn with “five wires”?
well, like stk200
There are still some questions that have arisen:
1.how to cut such a ROM (preferably the circuit :v2_conf2;);
2. Which bourgeois microcircuit can replace the VG93?
Hello, Bally
Such connectors are called sockets or “cribs” (as they say) they
soldered in exactly the same way as mikruhi
TIP: it is advisable to use collet sockets, although they are more expensive,
just BE CAREFUL with them, it’s easy to break the legs of the microcircuits!!!
2Mikka_A
And yet, how do you sew a flash drive?
Hello, Mikka_A
Gentlemen, I remember in Spec, processor mikruhi, and pzu-shek, were inserted into
special connectors - they are soldered in like regular microcircuits, or whatever
process, please tell me.
Cool instructions, - respect to the author!!!

The beds are soldered in like ordinary elements, there are no tricks.
And about the programmer - see post number 27.
There's a link there.

Isn’t there anything simpler? (It’s a pity to ruin mega8515 for him)
Hello, D-M

pfff.....where is it easier?
Atmega costs $2.4...
Hello, Mikka_A

So you still need to flash it.
And the person, as I understand it, has problems with programmers (and not with greed).
Hello, DimkaM
no, I’ll program all my megas and minis with the usual “five wires” (read
short course on AVR:v2_wink2; );

It's possible! Flag in hand! (Only later you don’t have to be indignant when you see the price of a finished

here; three ways.
first.
buy a finished product.
well, a product with ALREADY FISHED chips
second.
find people in your city who, for a certain amount
money/beer/juice/whatever else they'll screw you over.
third (in my opinion the simplest and most useful)

I worked in a "mailbox" for 6 years. And the boards actually passed State Acceptance
from representatives of the military customer.
The thing that bothered me the most was that we never knew what we were soldering. Some parts were soldered
in Leningrad, others in the Urals, a third in Kazakhstan, then it was collected under
Moscow...

At least they told us that it was... it was telemetry for the ISS. I personally hold it in my hands

installation on 1 board out of 15, the x-ray showed defective soldering of 1 BGA pin, after which
