Can any USB adapters power an 800XL? Looks not.
mozzwald replied to Sid Pokey's topic in Atari 8-Bit Computers
The adapters I make have been shipped with a 2A fuse. It's just an adapter and has no active power supply in it. Power is provided by whatever USB supply the end user has. I'd like to determine the highest current needed by a system with all the bells and whistles so the fuses aren't blown under 'normal' conditions. My thoughts now are to up it to a 3A fuse and possibly use a PTC resettable fuse so if there is an over current condition, disconnecting power will reset the fuse to a working state. -

It finally happened. Someone blew the fuse on 2 USB-C adapters. They were using it on an 800XL and 130XE with FujiNet and Sys-Check 2.2. So, this makes me wonder what a good value would be for a fuse. Has anyone done any testing on a "maxed" out Atari to see how much power it can actually draw with a bunch of addons / upgrades? -
there's a copy of it running at https://fujinet.online/fujifind as well. if you get a blank result, it's due to bots that are spamming the search. haven't figured a way to prevent that yet

It's still work in progress and requires new firmware which is not yet released (but you can build from source if you like)

FujiNet and Subcart - Should I expect any issues?
mozzwald replied to JohnFante's topic in #FujiNet SIO Network Adapter
I've not used Subcart before but there shouldn't be any issues. Just remember that when FujiNet powers on it will have it's config disk in drive 1 (unless you disable this from the Fujinet web interface). You don't want both devices configured with the same drives, ie, don't put a disk in Drive 2 on both at the same time or you'll have problems -
U-Boot is the bootloader and I suspect the button puts the device into FEL mode. Would be cool if someone could hookup UART serial and grab a log of the boot process. If kernel output is sent to the serial port, it could provide some useful info.

Parts arriving this week to make some more. If you get on the email list you'll get notified when they're available. I'm using an 800XL with 512k SRAM upgrade and FujiNet, so nothing excessive here. Of the 50 shipped so far, have not heard from anyone blowing the fuse yet. -

indeed, but I have seen some junky meters test leads show ohms. best to touch the leads together and find "0" before testing the components -

You should get 5 (or slightly more) Volts out from the USB power brick with no load. Perhaps your power bricks are "smart" and only do PD or IQ charging. Those features require "smarts" on the receiving end to negotiate the voltage and current. Or maybe the cable is not good. Check the resistance from USB to DIN ends for the power and ground wires as mentioned above Anything above a few ohms is not good. -

I see a UART port on the PCB and some other interesting pins (UBOOT, RECOVER) Whose gunna dump the NAND?

@Goochman you can follow the instructions above or power the FujiNet with a USB cable so that it is ready when the Atari boots. There are changes in the code to make Fujinet bootup faster but they are not available in a firmware update yet

if your network doesn't support mDNS or it's not working, you can always put the IP address of your TNFS server instead of a name
