SamCoupe scheme
ZXNet echo conference «hardware.zx»
Hello, All
Our Czech friend released the schematic for this clone:

Hello fan
This news makes me happy! I will be only too glad to have a semkupa for myself! Thank you, Roma
for the info!!!
Hello, CHRV
As I understand it ;)
ZY Somehow I have its modification SpeccyBob - SPECCYBOB 128 does not open,
password protected!

Yeah, but Pushkin will clone the chipset. Considering virtually zero interest
to newly pressed iron (and not to what is exchanged for beer/pepsicol)
and the reluctance of the majority to wave a soldering iron, only a maniac can recreate it,
purely for my own curiosity.
Hello, acidrain
I was pleasantly surprised by the graphical capabilities of this machine. It's even strange that
Iron workers avoid this topic in discussions. Why not use
SAM as a standard in the production of modern specks? This was probably the question
to CHRV :)

Hmm, I thought the chip was easy to get.
Then I don’t see any way out.
IMHO development and catching glitches of similar capabilities
device will take an immeasurable amount of time and compatibility?
Here it was at least somehow possible to transfer ready-made programs.
And the price can be even more insane, all sorts of looseness, matrix
the required capacity may also not be cheap.
Hello fan
fan> only a maniac will recreate it, purely for the sake of his own curiosity.
And I don’t think we need to recreate anything like that even
no matter how good the solutions are. Otherwise it will take a very long time
will choose and a lot of time will be spent on development, etc.
For 9990 was created for us long ago, it contains everything we need,
quite standard, well documented, easy to use.
So look up to him.
By the way, how are things going with the development of a distant video card?

B; In general, Lethargeek has already answered for me. I’ll add from myself that I would like
It’s interesting to try your hand at writing something (and further mastering
ASMA Z80) for this machine.
Just in case, I’ll give here a couple of links that (seemingly) have already flashed
in this forum:

ZY IMHO the ideal computer for some kind of school club.
Hello Costa
Cos> By the way, how are things going with the development of a distant video card?
There are already results...
Vitka Ronin draws a diagram, kick him :).
This really has nothing to do with the topic!
We get the chip normally and not at an exorbitant price (although more expensive than a bottle of beer
significantly)
Hello Costa
Cos> ...and compatibility ?
Cos> here it was at least somehow possible to transfer ready-made programs.
Compatible with what?
Transfer from where?
Hello, Black_Cat
Bla> It’s not clear what exactly surprised you?:confused;
This is; all the old spektrumist complexes regarding the number of independent
colors and pixels. ;)
But the speed of operation in these modes with graphics (and not only with graphics,
when the “seemingly fast” percentage is generally “killed” by the scanner) - no one is unpleasant
surprised?
I also advise you to pay attention to the percentage of puzzles to the rest
toys. :rolleyes:
Hello Lethargeek
Let> Compatible with what?
Let> Transfer from where?
Compatible with 99xx line (MSX)
A certain amount of software has already been developed for this chip.
All this has already been discussed in the topic "Turbo Video v9990".
Let's move the conversation there.

This answer already makes me happy: v2_yahoo:
Hello Costa
Is there a description on the computer somewhere? Like ports, video modes? Here
http://velesoft.speccy.cz/ ["http://velesoft.speccy.cz/"] nothing.

Cos> A certain amount of software has already been developed for this chip.
Yeah, somewhere there was already a thread about the quantity and quality of MSX toys.
:v2_conf2;
AND; Software is still always “for the computer”, and not “for the chip”.

And the topic itself is in "Other Computers". :D

About 15 years ago, if “everyone suddenly” turned to this platform, then maybe something would have happened
it would be, but this is fantasy, because then everyone was fighting for simplicity, and FPGAs were still
were unavailable. And now there is no point. Now this would degenerate into
another Siamese twin incompatible in ports and periphery. And although
technologically this machine is now available, but its train has left long ago. She doesn't
will solve existing problems, and will definitely add new ones.
Conclusion: it is better to develop what you have and not to spread yourself thin.
Hello, Black_Cat
Bla> it is better to develop what you have and not to be scattered.
The> mode 16 colors per pixel => 24kb screen and 47 thousand interrupt cycles
Well, the modes that we currently have are no good at all
No matter how you develop them, they are of no use 0. Only statics and no talk about dynamics.
But I just want normal dynamics.
Tempoly as I once said.
Let our Spectrum finally have a normal video card.
Whoever needs it will install it, whoever is interested in programming for it
he will program it. Why not?
Hello, CHRV
The> 47 thousand cycles in interrupt
Who has this?

Hello, captain cobalt
cap> Who has this?
in 16col mode the whole time the beam is traveling across the screen the percentage is -
71680-192*128=47104
Hello, The Exploited
SAMCoupe is not a standard machine - starting from the processor clock frequency and
ending with an immeasurable number of new ports. This means using it as
The only operating mode will be: either SAM or your usual Spec. Do this
ugliness is possible, for example, in a rebootable FPGA, but I’m sure it’s not for anyone
necessary (at least among those who can do it :smile; ).;
Conclusion: who needs SAM - take data from Czech colleagues and do it, or what
It's easier - use emulsion.

The link was posted as reference information - nothing more and nothing less. VeleSoft
plans to make a universal clone, so you can write to it.
