Oddly enough, I already have it in my hands :)
Looks great, will be something to do during the New Year holidays.

I looked on the ALTERA website to see who the official distributor is in Ukraine.
It turned out to be a lousy Kyiv office. I sent a request there by email - is it possible to
them to order this board, they replied that it is possible but the order will be completed 1...3
month and cost $170 + taxes. So it looks like any official
distributor ALTERA can safely order this miracle in addition to OBLIGATION (since
tinkering with one board is clearly a bummer for this company! but distrubutor requirements
They're probably obligated to do this.)
Hello, bigral
I also bought this DE1. What should we do with it now?
Hello dhau
Learn HDL :)

Give us Quorum-1024 based on DE1! :)
Hello dhau
dha> I also bought this DE1. What to do with it now?
Personally, I first tried the demos included in the kit.
Now I’m adapting the CPC source for TREX-C1 to DE1.
In the future, based on this code, I will emulate Spectrum.
The quorum will be 8 megabytes :)
Hello dhau

Make MSX ;) Fortunately, there are cheesecakes with everything you need.
Hello dhau
News from the company "EFO" www.efo.ru, www.altera.ru
12/19/2006
EFO LLC became a distributor of Terasic, which
offers debugging tools for Altera microcircuits.
Prices have been added to the price list.
TERASIC Altera Board 1 (DE1) - $186.90
TERASIC Altera Board 2 (DE2) - $351.30
Hello caro

It’s strange, but I couldn’t find the size of the board anywhere, if it’s not difficult, give me the size and max height
, I estimated somewhere around 13x13 cm?

I'm really very pleased with this news. It looks like this DE1 may well become
a real new Spectrum :)
caro, I will be the first beta tester of your Quorum-DE1, if possible :)

Finally :) It took them a long time to get ready ;)
By the way, I forgot to ask about the packaging - the set included plexiglass with
curly cutout for a button (and bolts for it)?
-+------------------------------------------------------------------------------
By chance, does anyone know if there is an SD&MMC -> CF(IDE) adapter?
IMHO for the SD/MMC support it is enough to stop at this option (while maintaining
compatibility with the Nemov controller) rather than reinventing the wheel with others
SD/MMC support options.

A little larger - 15x15 cm. But it still looks very small.
The maximum height is about 25 mm.

The board comes complete with this glass already screwed to it.
At the bottom there are threaded posts 10 mm high.

Hello dhau
dha> Tell me how best to pair the 2.5V Cyclone-II and the old 5V Spectrum?
dha> Say, if you want to use a real Z80 and AY?
According to the DE1 scheme, the input/output supply voltage is 3.3V
For CYCLONE II this means normal operation with 5-volt TTL logic.
Or make the connection through buffers on 74ACT or 74HCT logic powered from
3.3 volts.
Hello fan
What is this fee limitation?? Cyclones seem to be friends with LVTTL 3.3v
Hello, falanger
Gentlemen of electronics! Tell me how best to pair the 2.5V Cyclone-II and the old one
5V Spectrum?
Let's say if you want to use a real Z80 and AY?
Hello dhau
Probably through small circuits from the 74HC** family (powered by 2.5V).

What if you want to avoid cockroaches completely? Is it possible to use CPLD, which
provides the required amount of I/O, operates from 3.3V and is tolerant to 5V? If
use such a chip, it can completely buffer the I/O to the Cyclone-II.
I have a cheap old Xilinx CPLD Starter Kit somewhere, it seems to show
XC9500 and Cold Runner II. XC9500 works with 3.3V and understands 5V...
Hello caro
car> For CYCLONE II this means normal operation with 5 volt
car> TTL logic.
CYCLONE II has inputs/outputs that are not 5V tolerant, if the output is 3.3V per unit and can
power the usual logic, then the input designed for 3.3V (with a protective diode) is not,
because at one TTL (>4.5V) 4.5-3.3=1.1>Upr=0.7 (the protective diode will open) and
will cause the TTL output to short to the 3.3V source, the same problems apply to APEX
20KE and Stratix. (In our developments we used MAX3000A for pairing)
Hello dhau
dha> XC9500 works with 3.3V and understands 5V...
Well, this is what is written below (I only worked with altera, so I used
MAX300A) Xailinsk should have clearly similar CPLDs.
Hello caro
car> 100 Ohm resistors are connected in series with each line.
The problem is that with such inclusion there will be a blockage of fronts due to parasitic
integrating RC circuit, although for relatively slow cartridge-type circuits
or Z80 this is most likely not relevant.
Hello caro
car> That is, there is no problem
That is and you don’t need any mikruh??? %)

In the Datasheet Cyclone, it is written in this regard that input tolerance is up to 5
Voltage TTL logic is achieved by using an external resistor and
internal protective diode. Output operation is provided with a 5-volt
LVTTL, but not LVCMOS.
This is exactly how the connection of 5-volt cartridges is organized, for example in the diagram
1ChipMSX.
100 Ohm resistors are connected in series with each line.
In the DE1 circuit, all lines going from CYCLONE to external GPIO ports
also decoupled by series-connected 47 Ohm resistors.

Hello caro
car> Booting from SD/MMC is not yet supported.
It looks like this is the only real problem: (although I’m not at all happy
there is no second PS/2 connector on DE1, but there is a whole battery of diodes...).
The German threatens in an incomprehensible language about ... AVR der IDE Kommandos in MMC/SD
Kommandos... (I haven't looked for this one yet). I have never seen anything like this in *HDL.
How do you want to get around this moment?
Hello fan
fan> What I found - den CPC Trex C1 auf DE1 "Port" kannst Du von
For now this is only a demo version.
The keyboard is not supported (PS/2 is only one and is given to the mouse).
The original system on the Trex C1 was made with a CF flash drive, but since the DE1 does not have this,
then after starting the system, an error is displayed when loading files.
Booting from SD/MMC is not yet supported.

Just think :v2_smile:
Hello fan
fan> . I'm not at all happy about the lack of a second PS/2 connector on DE1...
I preferred to do the option with a mouse on the COM port,
leaving PS/2 for the keyboard.
But the SD/MMC connection is still a problem.
Today, perhaps the best option,
connect the CF card to the expansion connectors.
Hello caro

Well, you can hang the controller on the connector ;) (and then compact it into the matrix
him)

If anyone sees anything on the topic IDE <-> MMC/SD (preferably
homemade creation), then please let me know.
Hello caro

IMHO it is oil-free, they use the guts of the ROM cartridge to which (via
rework and special firmware) SD/MMC was initially connected. All kinds of interfaces with
IDE is a completely different story :(
Attempts at purely software use on AY ports seem to have been frozen for a long time
(there are cheese curds) - http://www.hat.hi-ho.ne.jp/tujikawa/mmc/mmc.html (translate
you can use this http://babelfish.altavista.com/ )
It turns out that it is best to switch to a new standard for the SD/MMC support
cards, highly preferably with a software organization of the protocol (without any
small controllers) at least for loading dumps.
Hello fan
fan> Just finding these monsters is a problem :(
Not a problem for me, I have 5 different ones :)

You can also dig into the source code of OneChipMSX, it is SD/MMC that is used there.
Hello fan
Finally, a month late, the payment arrived. Experiments can begin.
