NW Digital's DRAWS is pretty interesting I have mine together (it is a Raspberry Pi, a Pi HAT and software) and getting ready to solder cables and fire it up.
Anyone else looking at this?

I haven't heard of that one, what exactly does it do? (I can't google while offline at 40,000 feet ;) ).

I'd be curious too as my google search only showed a kit for
$150.00USD. A bit pricy for Pi stuff! and it did not tell me what it
did. Most of the pages that came up retured 404 errors.
Looks like an interesting project. What are you going to use it for?
While I have several RPi units (that mainly stay in the original shipping box) I've just seen way way too many cases where they simply do not hold up. One guy in 9 land I know went through so many when he tallied up how much he kept spending on replacements he finally broke down and got a
nice dell SFF PC for less than he spend on replacement Pis.

Any idea what the mode of failure has been?
I've broke two - hamfisted one trying to get it back out of a poorly designed case. It still works but I broke the camera connector,
Another one I think succumbed to static losing its WiFi chip which
again is more Operator Error than anything else.
But I've also run a Pi Based VPN as backup for about five years, and
have lots of other projects that have worked long term.
It does pay to note that not all RPis are equal, as there are a number
of builders. Since the whole RPi project orbits around an accessible prince point perhaps the economization of a manufacturer looking to
save product costs might not work out so well?
Certainly would think twice about using one for a mission-critical purpose. There are upgraded versions and other SBC that might be more appropriate.
Another of my RPi projects migrated the same way as this guy's did, but because of difficulties with the RPi supporting certain SSD hardware (current draw appears to exceed what the RPi will allow) so the project moved to a deskbook running Win10.

Not a problem. I'm still curious to know. I've heard abot NPR but
that's still a work in progress and it's design is such that there's a central point of failure.

Yes, I didn't like the hub and spoke model they used for NPR.
No, I just conducted myself and kept my potential down. ;)
I'd like to package it up for a portable digital setup to do some US/CDN Islands usislands.org and perhaps some POTA Parks on the Air.
Decided I am NOT dragging my Flex-6600M and a Laptop out for that sort of activation.
What radio will you pair it with?

Our packet group was supposed to get a demo of it. One guy even offered
to buy me a hub & spoke to play with! I sort of took that as an insult
as I can easily get my own if I were that interested in it. When you consider for spoke B to get to spoke D it has to travel through Hub A
it just didn't make sense. Granted, the speeds were supposed to be superior however my take is; if you can get digital radios to talk that fast on NPR why not through regular packet like they do in say Germany? They've been doing far more above 115,200 baud for ions. Our 1200 is child's play to them and not even something they wish to visit via the internet. You know it's bad then!

Just been my experiences with them and experiences shared by others.
Some have great luck with them. For a GO-kit they seem fine.

Yes, the EU hams have been doing high speed AX.25 for decades.
Impressive work there, but it never took off.

Slightly undecided - thinking one of old ones. Likely either a TenTec Jupiter or an SGC SG-2020

ax.25 is such a horrible protocol to begin with! It's MTU is only 256 bytes which is almost nothing. Add netrom, and now your MTU is 236 bytes... just horrible! Even at faster speeds, it's just a rapid fire
of frames, a plethra of packets, a disaster of data <G> On another
note, it is flexible enough that you can push quite a bit under it.

Most of my RPi's are in the original shipping boxes - I find that's the best place for them. When a site such as Google runs 100% on them,
perhaps maybe I'll consider them. Then again like Google I mainly run servers. Test cards just don't cut it... and the ax.25 stack on the
newer kernels is very broken - takes way too long to compile new
kernels.
Yeah, I've done pretty well with them.
Personally I have "ok" luck with the one I have in use, but I limit any writing to the SD card as much as possible. It's helped stretch out the life.
I gave one to a guy who's 80 and refuses to retain how to debug when it goes to sleep. I keep answering the same questions for him almost daily for 10 years now. Makes the whole hobby very UN fun.

Yeah that helps. The one the BBSs run on has a read only SD card. Writing is only done to the attached 500GB SSD. :)

My SSD experiments have been largely good, but did find that larger SSDs and non-sata3 ones troublesome.
I have one setup as a radio station eNotebook where my station building notes all end up at.

You got guts! I would *never* run a BBS on a Pi. Too many
read/writes. Before I run my monthly CloneZilla backups, I do a
mirror image of my SDCard so that also gets grabbed by
CloneZilla.
On an RPi-4 (and I think the 3B+ also), an SD card is not required at
all. I have a 4 that boots and runs from a 500GB SSD housed in an (externally powered) enclosure connected to the Pi with USB3. It runs 24x7 doing various things for me (not running the BBS), such as my DDNS updater, automated system-status emails, and distributed computing (the BOINC projects). Works very well and is fast. Again, it does not even have an SD card installed in it, and boots/operates from the SSD.

One thing that never ceases to amaze me is how versitile the flexnet protocol is for ax.25! It adds so much more that NetRom fails to deliver... and with ZERO additional protocol overhead! Just today, I
had to reroute a flexnet link then figured that I'd have to recode ALL
the IP routing for the various points involved.... WRONG!
One of these days I need to add IPv6 there :)

You got guts! I would *never* run a BBS on a Pi. Too many read/writes. Before I run my monthly CloneZilla backups, I do a mirror image of my SDCard so that also gets grabbed by CloneZilla. I have a very simple script that does it I call do-image. Here it is if you wish it:
#! /bin/sh
echo -n "What size in do you want (ex: 4M): "; read answer1
echo -n "Input device or file with path: "; read answer2
echo -n "Output device or file with path: "; read answer3
sleep 1
echo "preparing: dd bs=$answer1 if=$answer2 of=$answer3 is this
correct?" sleep 3
echo -n "This will take a L O N G while... "
/bin/dd bs=$answer1 if=$answer2 of=$answer3
echo "backup/restore done."
It uses DD... makes bootable backups. You can use it on almost any sort
of drive you wish to mirror really... and reverse things to do a
restore. Just make the input device the source and Output device the destination. I've had to restore my SDCard a couple times already when I've made a dumb typo <G>
Yeah that helps. The one the BBSs run on has a read only SD card.
Writing is only done to the attached 500GB SSD. :)
I tried using an external drive in a USB case... didn't fly well at
all. I just gave up on the RPi units for anything remotely server
related.
Hmm, that's a pain.
Very much so. Makes me sometimes feel as if my assistance really isn't appreciated.

I've been using PI's for many years now - started on the P1 (connected
to the TV as plex clients, powered by the TV) and now have P4's.
My main BBS ran on a PI3 for a good two years without any issues (on an
SD card). The Net 3 hub as well - for the last 18 months or so.
I've never had an SD card fail - I've had them for many years.
I'm very happy with the Pis.

Wow, I'm surprised by your issues.
I've never had an SD card fail - I've had them for many years.
(I lie, my P4 got really hot one day, because the fan failed - and it started getting I/O errors - but cooling it down seemed to fix it.)
Now my P4's run ESXi with 3 VMs - with a BBS in docker that floats
between the 3 VMs. Additionly its running on an M2 Sata - which is just
a USB device. With USB booting now (which I started using on the P4s),
I'm only using the SD card as a backup device.
I'm very happy with the Pis.
