The layout of the KiCAD files in ./Hardware and the Gerbers in ./Hardware/Gerbers.zip do not match.

Hello, would it be possible to offer a firmware with only the processor enabled? (Fastram and IDE disabled)
It’s for trying to use it on a CDTV.
Thank you

Halifax.

Hello,

Thanks a lot for your very cool project.
I'd like to know the exact reference of AT25 you used onto the board.
There are different memory capacities available.

Thank you very much!

Best regards,
Franck

I'm planning a redesign of Protein turbocard since I already bought cplds but have faulty batch of pcbs and people who successfully built them are complaining about its stability anyway.

So I'm wondering if this project's verilog code and schematic is a good reference for such redesign or are there some bugs which I should have in mind while reading sources?

Anyway, you're doing a very good work with keeping project files open, I really thank you for that. It's a priceless reference for me!

Hi,

Good day.

I have seen your really good job concerning this accelerator board for the AMIGA.

I just wonder if it's possible to add more RAM up to :

4x 1mb SRAM = 4 mb

AS6C1008-55PCN
SRAM 1Mb, 2.7V-5.5V, 55ns 128K x 8 Asynch SRAM

4x 4mb SRAM = 16 mb

AS6C4008-55PCN
SRAM 4M, 2.7-5.5V, 55ns 512K x 8 Asynch SRAM

Is there something that needs to be changed in the program?

Memory address?

Thanks in advance for your answers.

I cannot seem to open the project in my ISE version as it is complaining that my version is older than the one used for the project.

Could you please make it simple to program by creating a .jed file for use in impact?

Thank you in advance.

Hi there ,
I'm new in Amiga word , I have build one for my safe and struggling how to boot A500 from it ? Is is possible without FDD boot disk ? If kernel mod is needed by uploading IDE.devide lib. is necessary then how to do it ? . Anybody can help ?
Thank you !

Hello,

I try to make this project for my A500, I did solder everything except the RAM & IDE parts but I get a black screen on DiagROM.
Can it boot without any ram chip or something is wrong with my soldering ?

Thanks you
