There is definitely market for that

Xilinx is not getting how so I guess it's working ok. I think only last step left: programming CPLD but it will take me a it longer, need to prepare correct connectors. I was able to easily program Flash under Linux, I hope it should also be possible to program Xilinx without resorting to Windows machine?

all cables checked, no difference. Flash reprogrammed but for FPGA i will need jed but not sure if that is available for general public?

Hello Everyone I have Atari130XE and U1MB installed ~3 years ago. It was working fine until today. After powering on Atari, I just got brown screen. I checked all connections and no joy. Just to be sure all is ok with firmware, I've re-flashed with latest one (although before doing that i read current firmware and it was already up to date). To rule out Atari issue, I disconnected U1MB, installed original MMU and ROM and.. it works. Reconnected U1MB, checked all cables, seems be ok but issue persists. FPGA issue maybe?

It would be great as a newsletter that email has whole post. If not possible I understand there has to be link to site. Can that link be direct and not redirect through some tracking system?

great work!

old EPROMs are not that cheap, it might be cheaper/easier to get brand new PCBs and more modern EEPROMs

All good now, problem as usual was between chair and keyboard... Thanks again!

omg, wrong flasher downloading correct one now...

When I click Flash ESP I got an error Using '/dev/ttyUSB0' as serial port. Unexpected error: expected str, bytes or os.PathLike object, not NoneType I think It should download latest firmware itself, right? I can download one of Firmware from https://fujinet.online/firmware-dl/ but which one? firmware.bin?

I've built regular fujinet-v1 and it's exactly same error

@tschak909 I flash latest firmware (built from git head) and get an error like in post 2. Any idea what I may be missing?

I find that Micro USB cables are one of the most unreliable connections, I have tons of broken one, half-broken and just ephemeral broken...

This time I've used Official Flasher and Downloaded firmware, it flashed ok with different error in logs [16:35:18]ets Jun 8 2016 00:22:57 [16:35:18] [16:35:18]rst:0x3 (SW_RESET),boot:0x13 (SPI_FAST_FLASH_BOOT) [16:35:18]configsip: 0, SPIWP:0xee [16:35:18]clk_drv:0x00,q_drv:0x00,d_drv:0x00,cs0_drv:0x00,hd_drv:0x00,wp_drv:0x00 [16:35:18]mode:DIO, clock div:2 [16:35:18]load:0x3fff0018,len:4 [16:35:18]load:0x3fff001c,len:1044 [16:35:18]load:0x40078000,len:8896 [16:35:18]load:0x40080400,len:5828 [16:35:18]entry 0x400806ac

Looks like it was loose cable.

It says Hardware Version 1.0 and indeed that's what it's on board but i think it's already modified with some fixes. There is resistor on SIO connector It's not working but at least something is working, need to figure out what is missing now copy_file failed to open destination so I guess something with SPIFFS partition is not ok (or it's wrong assumption?)

Today I set up new environment, I've built new firmware commit 7f0dca365a658c50bdccc746b5ba0f26338277f0 (HEAD -> master, origin/master, origin/HEAD) Merge: dfc7374e 2d0c9e5d flashed and now my Fujinet is not working. When I connect USB cable all 3 leds blinks and go dark. FN is no longer recognized by computer. I bought that while ago and *I think* it's 1.3 hardware revision.

I think he did not mention new server as it is auto ban. LiberaChat? https://www.theregister.com/2021/05/19/freenode_staff_resigns/

this is nice, will be good to have such library on the side note, how do you generate all these sound data for engine? what is Your process for that?

I had similar when my PSU died and fried one of RAM chips

great news! networking games for a8 are flourishing :)

I was pleasantly surprised with https://cdn.myshoptet.com/usr/www.sintech-shop.cz/user/shop/big/6256-1_8144-scart-hdmi-2.jpg as as it worked well. Like @bfollowell mentioned, OSSC is great. Currently connected directly to NEC 1970VX and it's good as well.

Is that one https://hama.hu/termekek/70-tv-hifi-hazimozi/82-egyeb/a3182-scart-hdmi-konverter ? I had something that looked exactly same and wasn't good enough to pick up 15khz if that's what You are looking for. Maybe that one is different, but I've tried 4 different Scart2HDMI and only one was good and reliable

Thank You very much :)

these chips are 256k each, so if you don't have anything on other side, 4 of them makes 1mb per simm
