4 new platforms

[tcdev]

Added 4 new platforms tonight - all from other sources.

* Apple II+ by Stephen Edwards (DE2)
* Apple IIe by Alex Freed (DE1)
* Spectrum 128 by Alex Freed (DE1)
* Vector-06C by Viacheslav Slavinsky (DE1)

None of the projects have been shoe-horned into PACE yet...

Hi Mark,

do you know details. i.e how to load from mmc card in Alex Freeds Apple 2
and ZX core ?

Hi Mark,

do you know details. i.e how to load from mmc card in Alex Freeds Apple 2
and ZX core ?

Sorry Dirk, I haven't had time to play with them - I only discovered them last night! I did build them both - and discovered a few files were missing from the Apple project that Alex subsequently uploaded - but not having access to a DE1 I need to port them to either P2 or DE2 before I can play...

Hopefully I'll get the chance sooner rather than later! I'll post results here when I do!

Since yesterday in the apple source folder of Alex´s source is a howto.txt file.
There is the missing apple rom,too.
In short:

The zx core needs a Spectrum 128K rom starting at flash adress 1000000.
Only Spectrum 48k sna files are supported.

The apple rom must be flashed at 000000.
Only nib, no dsk files are supported.

The sd card must not be fragmented !!!


I have ported Apple II+ by Stephen Edwards (DE2) to DE1 Board.
It works but i didn´t test the sd interface until now.

I am trying to get this Spectrum image working on my DE1.

You said to load the Spectrum 128K image at 100000.

0x100000 = 16777216 this is bigger than both the flash and the SDRAM.

Do you mean load the image at 64K 0x10000 ????

Thanks in advance for any help you can give. I am having a Torrid time getting any projects to work after a long lay off from FPGAing.

Cheers.

I emailed Alex Freed and asked him about his ZX Spectrum 128 DE1 project.

He has kindly replied.

Dirk is of course wrong as he had to be as his address was out of range of the flash chip.

Alex says that the 32k spectrum ROM should reside at 0x100000 (1MB). The ROMs I have are from the Mess Project and are in fact two 16K ROMs which I guess together make the 32K one described by Alex?. I tried programming the Mess ROMs consecutively at 1MB and loading my spectrum sof and I just get the same picture on my screen that I get when I have not programmed my ROMs. I tried with both the 0 ROM first and the 1 ROM first.

Well I get this :-

So it looks like a Spectrum on my DE1 still eludes me :(.

Well at least I had and IBM PC Compatible working as the Zet project is going well now.

I'll have a look at it ASAP.

It would appear that I've never built the DE1 version of Alex's Spectrum. I've only built it for my custom hardware, and in that case I built the roms into the image.

You could run a hex2bin utility on the spectrum roms I have in the repository - I can't recall where I got them from.

If you give me a few more days I'll try to find the chance to build it for the Spectrum and see what I can deduce.

Update: just re-built for my custom hardware, and I just get a white screen... :(

Hi,


Finally ,I can post. Thanks to Mark.

Got the De-1 (the model that cannot run minimig) to run Alex's spectrum.
You need to use spectrum128 rom at 0x100000

Compiled with Q8.1.
galaxian.sna runs but not perfect
jetpac.sna didn't run

Basic works ok.

I'm not sure if its Q8.1 or the code or the model of my DE1.
