Hello, All
I'm trying to assemble all the logic including RAM and ROM on an altera cyclone..
All that remains to be taken out is the percent and vg-shka. no one tried with static RAM
work???
Hello icebear
ice> Cyclone - not too much? Look at the topic "Question about memory". What about DRAM
ice> not satisfied?
Just.. :-) but how many additional things can be added and all without modification
boards...
As for the dram, the cyclone has a sram inside, and it doesn’t have very many legs...
only 240 :-) in my version. EP1C12Q240C6 it is installed on my board
evaluation kit

Are you satisfied?
Hello, serg.ne@

ser> I see.....
ser> but I can’t understand how it will work in speccy....
In what sense "how will it work"? If you need a SRAM wiring diagram
to the Spectrum, then look in the topic "Question about memory." Based on this scheme you can
make your own using Cyclone's Block RAM. By the way, I made the filling for the Cyclone
circuit input or described?
Hello, serg.ne@
ser> Exactly.. :-) but how much you can add additionally and all without

What is true is true.

ser> a lot...

Wait, the question was how to use SRAM Cyclone or how to use SRAM
at all? If the first, doesn’t Altera have a corresponding AppNote on its website?

Well then you have a direct route to www.opencores.org, there are already two cores - T80 and
Wishbone HP Z80. It will fit 100% into the Cyclone along with the rest of the circuit.

Emulating the z80 is too much, cost inc has ready-made solutions, but it’s worth it
under $10,000, but if it were, I would gladly stuff it there.
As for armatures, they are definitely expensive and not very convenient.
and as for cheapness, it’s not that expensive, and if you already have a board, then
why not suffer...

Thank you, I have already started.....
Hello icebear
ice> By the way, I made the filling of the Cyclone using a circuit input or described it
I redrew the diagram... I probably don’t have the patience to describe it

How to use sram in speccy... I understand everything about the cyclone one.....
but I can’t understand how it will work in speccy....
Hello, serg.ne@
Not a cheap solution at all!
And the deposit is external or also emulated.
Regarding controllers, it’s better to take some kind of ARM7 with internal memory... HERE
will really be in your pocket.

It seems to me that the whole problem with AVRs is that the AVR code is only on the crystal
can be executed, and everything else is done by the interpreter (so to speak :)). What to do with
everyone else speck with iron?

AWS is inexpensive :).

ser> yes, why not suffer.....
Well, on the contrary, it’s interesting! The Sprinter 2000 turned out to be a super thing, it’s a pity that it
The Peterses screwed up their business.

Okay, tell me the price of one Sprinter of your build :) Then I’ll calculate it myself.

How much did they ask? You've never mentioned a specific amount yet, alone
hints. Or is it a secret?

Indeed. Well then, as many as three cores. By the way, there is also a commercial core
Z180.

if I understood correctly 200 pieces * 15 years * $116 = $348,000???
I doubt that they sold 3000 cars :v2_unsur:

It would be interesting to look at the implementation of all the logic in acex.....

I believe that about 30 thousand are green....

Russian - decency.
Hello icebear
ice> Okay, name the price of one Sprinter of your build :) Then I will do it myself
ice> I'll do the math.
I apologize for the mistake, it turned out not 200 sprinters per year, but 20 of course :).
I won’t name anything, the amount is estimated at several thousand dollars.

This question is not for me but for Ivan Mak, but since he works for the Peters, and they
everyone wants to sell the project to someone for really unimaginable money (I thought that
to get them back, if I sell 200 sprinters a year, I’ll need 15
years), then we will probably never hear the answer :). Amen!
