Hello, All
Friends, I beg you not to be lazy and measure the distance between the slots
(SNP connectors) on this expander.
If possible, you can also attach a photo.
I would be extremely grateful!
Thanks in advance!

I suggest making the distance between the slots as in a PC (ISA, PCI). It's already
established practice and all bodies have exactly this distance (this is true, on
every fireman).

I agree.
optimal distance.
maybe a little less.

It seems to mean that the expander is buffered.
The diagram is here: http://zx.pk.ru/showthread.php?t=3940
Offer options, I would like to know an option that can suit everyone.
Hello, Mikka_A
You caught the train of my thoughts. I agree with your opinion.
But what about the number of slots? I think that if you do, then no less than
4 slots (and on one side, like on the Scorpio expander.)
What are your opinions, gentlemen?

So what about buffering? Like IR23 and all that...

My opinion:
Make sure that the board fits against the slots for boards in the standard
case, be it AT or ATX, it’s not difficult to make a double set of holes for mounting.
And actually it’s time to make expansion boards “ears” for standard mounting
and connectors. The board should have a connector for connecting to the specs from the end, i.e. closer to
face of the case, so that you can stick a scorpion there with a connector soldered to the side of the board,
or just a regular connector with a cable to any spec. Or maybe with two
"combs" from the end and from the top or bottom, i.e. like a standard Christmas tree. Of course
at least 4 slots, I think six would not be out of place, the question here is rather
the size of the fee and, as a result, the cost.
Is everything buffered of course?

It will glitch ungodly, or even the percent will start smoking - its load capacity
not limitless!

So what about the option I described? Not for, not against, no one

- 10,11,12 cm.
What is your opinion?
Hello Mike
Mike, I'm sorry, but no matter how hard I tried to strain my spatial
imagination, I still didn’t understand your second post. :) Maybe you can draw it
schematically? :)

Hello Mike
As Stirlitz said: everyone can criticize and... that, but offer something specific
decision...
That's just what Mike suggested; Gentlemen, feel free to share your thoughts! :) In a dispute
truth is born! :)
I have already outlined my vision, now I dare to add a fly in the ointment to Mike’s idea:
1. Not everyone has boards the size of Scorpion ZS 256 Turbo+ (personally, I just have
Turbo and it doesn’t fit into a minitower in height :(, I’m not even talking about all sorts of
pentagons and other widespread ZX's), meaning that no
confidence that in the same plane, as in the figure, it will be possible to place and
board and expander.
2. Complication of the device due to triggers for power supply and so on... You understand,
unnecessary complexity in design means unnecessary complexity in production... etc.,
I'm afraid it won't end up being expensive.
3. How many ZX devices are there in the world with a bracket for the holes of the AT/ATX case? No!
Why fence a garden? For example, you can buy separately for the Kamilev card
bracket in any computer store and bring everything beautifully to the rear end
housings (this is how I did it, for example)
4. Looking at the picture, I understand that if I don’t insert General Sound, it won’t fit,
because it is wide. Uncritical remark.
5. I also thought about the electrical connector, i.e. planned to be attached to
bus expander connector as on a 5'25 drive with +5 and +126. Theoretically, the circuit from X-Trade is capable of supporting 6 devices. In reality -
4-5. That’s why I suggested making 4 slots so that there would definitely be no glitches (even though they
and some people like it ;)).
I also forgot to write that I like the location of the expander at the bottom
minitower cases (fasten with 4 screws), so the devices in it will be
parallel to the motherboard.
PS; Not; I want them to bombard me after they make the nth number of boards for me
rotten eggs. Don't pass by! Everyone needs ZXBUS (it's like a mobile phone:
no and don’t need it, and if there is, then it’s unclear how to live without it :))

I agree, but now in stores there is a large selection of completely different cases
sizes and at completely different prices, so you can choose for any spec.
Evg> 2. Complicating the device due to triggers for power supply and so on... Itself
Evg> you see, unnecessary complexity in the design means unnecessary complexity in

But this is not a significant complication, practically one or two small bodies
loose powder and a little binding and again, you can dilute it, but solder it or not,
this is a separate question. And it won’t take up much space on the PCB, so
the price will remain virtually unchanged.

Evg> everything is beautiful on the rear end of the case (this is how I did it, for example)
I personally drilled four holes in my AT case, in places where it was convenient
me, screwed four bushings and mother on them. The whole operation took about ten
minutes. Moreover, it almost damaged the body. Yes, and with such a mass
"Christmas trees" with boards, it needs to be attached somewhere.
Evg> 4. Looking at the picture, I understand that it’s not possible to plug in General Sound

Is it sticking out into the back of the body? This can be thought about...
Evg> 5. I also thought about the electrical connector, i.e. planned

Sound idea. That's right - screw the AT connector, better than molex (5.25"...) and ATX IMHO.

Evg> in reality - 4-5. That's why I suggested making 4 slots to be precise
Evg> there were no glitches (although some people like them ;)).What if we essentially duplicate it? Assemble two three slots and load them onto the bus
spec. You can even not solder half of the slots with loose solder, for whom three is enough -
again savings.
Hello, Mikka_A
Mik> And I prefer the idea of an expander in one line with the board, but
Mik> devices are perpendicular to it. :v2_rolley
This is only implemented in brands, i.e. when the body and mother are made as one
system, in the sense that you can’t put anything else in such a case without an angle grinder, equal
like the mother in the other. In general, not our option - absolutely not universal. Yes and in
With such constructs there were problems with contact, from loosening the tree in
mother connector. I had brands (Compaq and IBM), I am not familiar with this
by hearsay.
