You've turned out to be quite a treat, congratulations. What is the approximate cost of implementation because maybe I would do for myself? Out of curiosity, hand or machine soldered? You could throw in the parts list even from the program because probably not everything is on the diagram.
I have no idea, I do not buy individual items. There are many boxes lying around and I take out what I need.
Hand soldered out of curiosity
=============== update ===============
I tried the second core C64 approach yesterday. So far I haven't been able to match it with the SDRAM controller. Certainly it is possible, but without knowing the timings, it's hard to do it. It will take some time to analyze this. Core running on the internal GRAM works, but it's only 40kB.
If you have it, you can give it to me because I've never seen it ... and 5.25 with a working station would come in handy. I will also gladly take the Amiga 500 (but not qwertz) if someone has it, because I don't have a keyboard for testing.
Maybe I still have 5.25 "ignition switches, as I did not open it. Because they have cool stepper motors (such for PC as you are interested in) 8" floppy disks (as someone still remembers the name) but no ignition (they were used in Polish PSPD devices (https : //www.youtube.com/watch? v = Svxmq08Ow_I) produced by MERA-KFAP in Krakow They were produced in two pockets so that it was 2x 256kB . After the introduction of CPM v1.0, the computer had up to 64kB in dynamic memories.
great job, I'm finished and delighted with the relatively small amount of components.
I have four questions.
1. Some resistor values are not on the list of elements, ie are they jumpers or aren't they mounted? 2. As I understand correctly, to have a different platform, FPGA should be reprogrammed or maybe in the menu it is possible to choose the platform that will be loaded - it would be great but I understand that there are some limitations. 3. Will there be an implementation of C64 and the ability to load files into it from an SD card 4. What configuration was the Wolfenstein fired on, was it Amiga or something else?
If you would like the housing, I can design and print it on a 3D printer, you can then share it - if you wish
A few programming related questions. 1. Configuration is programmed by JTAG and is it used for "main (v0.4 beta2) .bin"? 2. Can it be done with the FT2232 converter? 3. The remaining files are loaded from the SD card? I see there are NES and Spectrum files, and Amiga?
The first time you have to load MAIN to flash with some programmer. Alternatively, upload main_xxxx.a586 to fat32 card (main partition), run fpga via jtag, and F2 update (it will be uploaded to flash).
I include the card image (DOS_ClassicWB.raw.zip). The first dos partition (it's just command.com) of the core PC. Second Amiga, don't change. Make the third fat32 (as the main one). You will throw roms or other files on it.
