Wait, what do you mean used for uploading cores?

If card works for *.A586 uploading, it should work with amiga disk image.

Ah right. Got it. I will try few different cards. Just in case.

Wooohoooo!!! Sucsess!!!!
So not all SD cards are made equal... not a big news... This 4GB card works for me. This is the same card I was using for programming DIY in the first place.

Thanks a million Piotr!

Fantastic!

Hi

I was able to create a board and display the menu, but which is the core file for the Amiga?

Hi Piotr, great project!

Will you be releasing the Verilog for the Amiga core in the future? It would be interesting for learning.

Thanks.

Here is the preview of the case. This is not final design. Now I am implementing some improvements suggested by Piotr.
We are days away from production. Any preference in terms of colour and finish for the case?

Btw, site https://www.diy-a586.com is progressing well. I will expedite development so we can have one place where people can get support, license keys, claim warranty if needed and finally purchase boards, cases, power supplyes etc..
Perhaps getting healty stock of PS/2 keyboards and mouses is not a bad idea. Also we will try to keep prices lowest possible so everyone can afford assembled boards.

Since board is "open design" we will also make sure everything is available as DIY kit - Case design, component locator, software, precise component specs etc...

I will keep you posted.

I made one of the copies with something like that. Height 47mm. I just need to print the sides.

From a piece of laminate I made a board connecting the floppy disk drive with the "motherboard".
Brass threaded spacers are soldered to the laminate.
3D printed bottom.

Hello
I have one more question, is it possible to solder the pins in the marked part in the photo and lead out the reset and menu switches?
Thank you

Hi
It is true that I have a plate for a long time (from Amiparty), but recently something motivated me and I soldered the emulator Generally, the first firing resulted in such a picture.

Shouldn't there be something on the menu at startup?
Before soldering flash, I programmed it with the main file.

You still need to upload core and roms.
(core sent to PW)

Hello

I am trying to run two floppy drives but cannot. Did you manage to run two? I have two pc stations converted, one df1 and the other df0 and a crossover cable for Amiga. However, ndos the game sees the DF1 station, it cannot read floppy disk number 2, but tries to read and that's it. Workbench cannot see the df1 drive and boot menu. Xcopy only blinks LED and that's it. Please help. Thank you. greetings

The mating itself with 2 real stations will not do anything. You need a second engine signal and a slightly modified core.
There are 2 options:
- External signal latches / MTR0 / MTR1.
- / MTR1 instead of the / INDEX signal
What you choose?

Version with ps / 2 or amiga keyboard?

I have a PS2 core. Just don't know how to do signal substitutions or this external version. Do you have any instructions? I have two pc Alps stations. Thank you

I sent a modified core to PM.
/ MTR1 is on pin 8 instead of the / INDEX signal

/ SEL0 (10) / MTR0 (16) one station
/ SEL1 (12) / MTR1 (8) second station

Let me know if it works because I only tested the flop + emulator.

Version with / MTR1 instead of / INDEX:

I will try to insert the diagram with a latch later.

Hello.

I'm trying to upload this core, but Fat32 error keeps popping up, I don't know why. This tab works with Workbench. Card formatted for Windows FAT32.

Here the housing is not finished yet.

The card must have MBR and FAT32 partition as primary, not extended.

Ok, the Core was replaced. However, it doesn't work. Can you send a picture of your tape to the station. I don't know if I have a well-crossed cable. Thanks

I have done this.

I don't have 2 Amiga stations and the emulator I have doesn't require changing the connections, so I didn't make the cable.
You crossed the wires (4,6) that are not connected. Take a look at the diagram I have posted.

Yeah. My stupidity. On the second station I crossed 4 and pin 8 as well as 10 and 12. Should it be like that? However, my abilities are too weak.

I also led mtr1 to pin 16.

Pin 8 in the stations do not connect because the index signal will interfere.
Ideally, you should connect the signals / SELx and / MTRx only to the correct station and not in the other one.

Ok. I'll try again sometime. For now, I give it up. Can gotek be connected to this core and will it work as DF1 on a simple double tape? Thanks. greetings

Standard core is better for gotek.
On a standard core, the real drive must be DF0, gotek DF1 (or DF0 if itself).

Hello

I was able to connect the DF0 and gotek DF1 stations and everything works except for the FF program for gotek. After its launch, there is only a blank screen. Works fine on Amiga 500. I am using flash floppy 3.22 do you have any idea what could be causing this? However, the problem of the two stations is caused by the reworking of the stations, because even one of mine had a problem with goth. Someday I will make more attempts ?

Yes, the same, black screen, you can't see anything.
The program loads both under Workbench and Goteka, nothing is displayed, only a black or blue screen.
I tried kick 3.1.4 and 1.3.

Topic summary

The discussion revolves around the DIY-A586 v1.6, a retrocomputing emulator designed by Piotr Go, featuring an FPGA Spartan6 XC6SLX9, 8MB SDRAM, and various connectivity options including HDMI, RS232, and joystick ports. Users inquire about programming the FPGA, configuring floppy drives, and compatibility with different ROMs and cores. The author provides updates on core development, including support for Amiga and PC emulation, and addresses technical questions regarding component specifications, programming methods, and troubleshooting issues related to SD card usage and floppy drive connections. The conversation also touches on the potential for future enhancements and additional cores for other systems like C64 and Atari.
